Local Florida natives Dr. Sidney Chanutin and Dr. Sierra Chanutin have always aspired to become veterinarians. The twin sisters have been immersed in the equine industry their whole lives. Throughout middle school, high school, and undergraduate studies, the sisters dedicated their free time to shadowing and working at Palm Beach Equine Clinic in Wellington, FL. Sidney and Sierra earned their Doctor of Veterinary Medicine degrees at the University of Florida.
Afterward, Sidney returned to her hometown to complete a yearlong rotating equine internship at PBEC. She then remained at PBEC as an associate veterinarian and completed her residency in equine sports medicine and rehabilitation under the mentorship of Dr. Chris Elliott. She is a diplomate of the American College of Veterinary Sports Medicine and Rehabilitation (ACVSMR).
Outside the hospital, Sidney enjoys time in the saddle, riding her personal horses, or out on the ocean with her husband, George.
After graduation, Sierra pursued advanced clinical training, completing an internship at Texas Equine Hospital and a surgical fellowship at Equine Sports Medicine and Surgery in Weatherford, TX. She later returned to Florida to continue her specialized training, earning a Master of Science in Veterinary Medicine while completing a large animal surgery residency at the University of Florida.
In March 2026, Sierra rejoined PBEC as an American College of Veterinary Surgeons board-certified large animal veterinary surgeon after completing her Phase II board examination.
Outside her clinical work, Sierra enjoys spending time with her beagle, Cassie, and riding her Quarter Horse, Ruby.
Can you detail your history at PBEC? When did you start working there?
Sidney: Growing up in South Florida with our own horses, Sierra and I trusted PBEC to care for them. We also spent countless hours shadowing many of the doctors throughout high school and undergrad, and we returned for externships during veterinary school. After graduating from veterinary school, I completed a yearlong internship and then stayed on as an associate with surgeon Dr. Weston Davis. When sports medicine specialist Dr. Chris Elliott joined PBEC, he approached Dr. Davis and me about starting a sports medicine and rehabilitation residency, and the pieces fell into place.
Sierra: Sidney and I spent many years shadowing veterinarians at PBEC throughout middle school, high school, and our undergraduate studies. My path back to PBEC after veterinary school was longer, including an internship and a surgical fellowship in Texas, followed by a surgical residency at the University of Florida. Afterward, I returned to the clinic, joining Sidney and bringing my additional training and experience.
What made you choose to become a veterinarian?
Sidney: Caring for animals has been my passion since before I can even remember. Becoming a veterinarian has always been my goal; I guess since the womb.
Sierra: Sidney and I have aspired to become equine veterinarians for as long as we can remember. There was no single defining moment that led us to this path; rather, it felt like a natural calling, one we recognized early on as the career we were meant to pursue.
What made you choose PBEC for internship/residency?
Sidney: The long-standing relationship I had with PBEC’s veterinarians and the fact that South Florida is home to me were major draws. I also chose PBEC for an internship because it is one of the most prestigious equine hospitals in North America. The high caseload and the multitude of exceptional veterinarians (including boarded specialists) with diverse backgrounds make it an ideal internship opportunity.
What piece of advice from another vet has stuck with you?
Sidney: Knowledge is power, and you never stop learning in this job.

What was the process like for passing your boards? Can you tell me what you are board-certified in?
Sidney: The residency was a three-year program that included seeing many sports medicine cases, accumulating hundreds of continuing education hours, publishing a paper in the Journal of the American Veterinary Medical Association, and passing the rigorous board examination this past February to become certified in Veterinary Sports Medicine and Rehabilitation.
Sierra: To achieve ACVS board certification, I completed a rigorous four-year residency program, published original research in a peer-reviewed medical journal, and passed comprehensive board examinations. I completed my surgical residency at the University of Florida, where I had the privilege of learning from internationally recognized surgeons. As part of my training, I spent a year researching blind-end closure techniques for jejunocecostomy, a complex intestinal anastomosis used in colic surgery when ileal resection is necessary.
How does being board-certified affect your work?
Sidney: Board certification in sports medicine and rehabilitation has given me advanced knowledge to diagnose, treat, and manage lameness and poor performance in all types of sport horses.
Sierra: Earning board certification through ACVS has equipped me with the advanced knowledge and technical expertise necessary to practice at the highest standard as a veterinarian and surgeon.

Do you have any further educational goals?
Sidney: For now, I’m just enjoying using my knowledge to help horses and clients achieve their competition goals. Eventually, I would like to have my own resident to continue sharing knowledge.
Sierra: As a valued mentor once said, “The journey does not end with board certification. It has only just begun.” In that spirit, I remain committed to providing the highest standard of care to my patients by continually advancing my knowledge and skills as a veterinarian and surgeon. While I do not plan to pursue additional certifications, I am dedicated to ongoing professional growth through collaboration with colleagues and continuing education to ensure I deliver excellent, effective care.
Why did you choose your specialty?
Sidney: Performance and lameness issues in the sport horse have always been a large part of my day-to-day work. My goal is to help my patients as much as possible, so completing a residency in sports medicine and rehabilitation was the natural choice.
Sierra: Surgery is an exceptionally demanding specialty to pursue; however, it offers a level of professional fulfillment that is truly unparalleled. Whether responding to critical emergencies or helping patients reach peak performance, I take great pride in contributing to their well-being and providing meaningful support to their owners.
What do you enjoy most about working at PBEC?
Sidney: PBEC has given me so many exceptional mentors who have provided me with the knowledge to become the veterinarian I am today. I can’t express enough how grateful I am to each of my mentors and colleagues.
Sierra: What I value most about PBEC is the opportunity to work alongside highly skilled veterinarians across multiple specialties. This collaborative environment enables us to share expertise and consistently deliver the highest standard of care to our patients.

Dr. Sierra Chanutin

Dr. Sidney Chanutin

Originally from Long Island, NY, Dr. Michelle Maguire developed a passion for equine veterinary medicine through years of competing on the hunter/jumper circuit. She earned her undergraduate degree from the University of Miami in Florida. During summer breaks at home, she began working at Cornell Ruffian Equine Specialists, where she cultivated a strong interest in equine surgery.
Dr. Maguire received her Doctor of Veterinary Medicine (DVM) from Western University of Health Sciences in 2021. During veterinary school, she also pursued training in traditional Chinese veterinary medicine and became a certified veterinary acupuncturist (CVA).
After graduation, Dr. Maguire completed a rotating internship at Rood and Riddle Equine Hospital in Lexington, KY, and then went on to complete a surgical residency at Palm Beach Equine Clinic in Wellington, FL. She became board-certified by the American College of Veterinary Surgeons (ACVS) in February 2026.
Outside of veterinary medicine, Dr. Maguire enjoys riding her own horses, weightlifting, and spending time outdoors with her boyfriend, Nick, and their golden retriever, Murphy.
What was your path to vet school, and why did you choose it?
I’ve wanted to be a veterinarian for as long as I can remember — really, since I was old enough to understand what that meant. I’ve always felt a strong connection to animals and a desire to care for them, so this path felt very natural to me. Over time, that early interest grew into a clear goal, and veterinary medicine became the perfect way to turn that passion into a career.
What interested you most about learning more about equine surgery?
Early on, before veterinary school, I had the opportunity to work alongside equine surgeons, and I was really inspired by their skill, attention to detail, and the level of care they provided. That experience sparked my interest and showed me the kind of clinician I wanted to become.
I’ve always been drawn to surgery because it’s very hands-on and detail-oriented. I enjoy working through complex cases and solving challenging problems, and that’s what continues to keep me excited about equine surgery.
Why did you come to PBEC?
I was first introduced to Palm Beach Equine Clinic while competing at the Winter Equestrian Festival, where I relied on PBEC veterinarians to care for my own horses. On the day I was accepted into veterinary school, Dr. Bob Brusie was performing a lameness evaluation on one of my horses. After I shared the news, he took a moment to show me how to perform a nerve block. While I already had a strong interest in equine medicine, that experience stands out as a memorable early interaction with the PBEC team.
Soon after that, I visited the clinic and observed surgery firsthand, which reinforced my interest in the field. During veterinary school, I completed two externships totaling five weeks. Through those experiences, I was drawn to the team’s expertise, collaborative environment, and the advanced techniques and modalities available at PBEC. Additionally, the diverse sport horse caseload in Wellington, combined with a robust surgical volume, makes it an ideal setting for continued growth and development.
What was the surgical residency program like, and what did it teach you?
PBEC is one of only a few private practices in the country approved to offer a surgical residency program through the American College of Veterinary Surgery (ACVS). To meet those standards, a hospital must provide a very high level of training, including access to board-certified surgeons, advanced imaging, and a wide range of complex surgical cases.
What made the program especially valuable was its collaborative environment. We worked closely with specialists across multiple areas, such as internal medicine and radiology, and we managed complex cases together in real time. That kind of hands-on, team-based approach is what really shaped my training as a surgeon.
Can you explain what it means to sit for AVCS board certification? What does that diploma grant you?
Sitting for ACVS board certification is the final step in a very long and rigorous training process. After completing veterinary school, you go through several additional years of specialized surgical training, during which you not only performing a high volume of complex procedures, but also training in other areas like anesthesia, imaging, and internal medicine, and contribute to research.
Once that training is complete and your credentials are approved, you’re eligible to take the final board exam. Passing the exam grants you Diplomate status, which means you’re officially recognized as a board-certified veterinary surgeon. It signifies a high level of expertise and a commitment to the highest standards of surgical care.
PBEC has six other board-certified surgeons – have you worked with all of them? What is something important they have taught you?
I’ve worked closely with all the surgeons at PBEC, and that kind of collaborative environment has been invaluable. One of the biggest takeaways from my training has been the importance of sound judgment — understanding the full picture of the horse, the injury, and the long-term outcome, rather than focusing solely on the surgical procedure.
Are there certain types of surgery that interest you more than others? How many surgeries do you perform each month?
Early on, I thought I would focus primarily on orthopedic surgery — things like fractures and joint injuries. But in real-world practice, you have to be ready to handle whatever comes through the door. On any given day, that can mean everything from airway surgery to a broken leg to an abdominal emergency.
Over time, I’ve realized that’s actually what I enjoy most. I don’t just like one niche; I really enjoy the variety. Each case has its own challenges, making the work interesting and rewarding.
We typically do between 20 and 60 surgeries per month, depending on the time of year.
What is the feeling you get when you see a horse rehab successfully from its surgery?
There’s nothing better. You meet these horses on what can be one of their worst days, and seeing them come through surgery, recover, and return to a comfortable, active life is incredibly fulfilling. That transformation is what makes the job so meaningful.
It’s also very special to help their owners and riders. Giving someone more time with their horse — whether that’s back in the saddle or simply enjoying their companionship — is one of the most rewarding aspects of this job.
Are there any further steps to your veterinary education?
Veterinary medicine is truly a field of lifelong learning. Even after completing formal training, we’re constantly learning through conferences, new research, and collaboration with colleagues. Staying current is essential to providing the highest level of care for our patients.




Dr. Jamie Klements joins the Palm Beach Equine Clinic in Wellington, FL, from the Midwest, where she operated her own practice as an equine chiropractor and acupuncturist. With a passion for learning, Dr. Klements has a wealth of knowledge on equine wellness and comes to the clinic to apply her skills to sports medicine alongside PBEC’s Dr. Bill Patterson.
Q: What made you want to become an equine veterinarian?
A: I was one of those kids who was born loving horses. My family didn’t own horses, but I took riding lessons and worked in barns as much as I could. I rode in the hunters as a hobby, but never as a professional. I was pre-med for most of my undergrad schooling. I started spending time with my horse’s veterinarian during my junior year of college after a summer job at the Cleveland Clinic determined human medicine wasn’t for me. I love horses and medicine, and the switch made sense. Today I am still grateful I get to work with horses for my job.
Q: What’s your background in veterinary medicine?
A: I’m grew up in Ohio and attended Miami University in Ohio for my undergraduate degree. I went to vet school at Iowa State University. After graduating from vet school, I worked at Lebanon Equine Clinic in Ohio for two years. In 2017, I started my practice called Midwest Veterinary Chiropractic and Wellness that focuses on chiropractic care and acupuncture treatment for horses. I am located near the World Equestrian Center in Wilmington, OH. I have worked as a show veterinarian and see my clients at their home farms or at the horse show for acupuncture and chiropractic care.
Q: What drew you to equine chiropractic and acupuncture, and what was the training process like for these specialties?
A: I’ve always had dachshunds, and while I was in vet school, I had one that needed back surgery. There was a vet at the practice who did acupuncture on him, and it helped him so much with his rehabilitation. Seeing how positively the treatment affected him made me interested in learning how to do it for my own patients.
Currently, neither acupuncture nor chiropractic is a boarded specialty but a certification training program that is available after you are a veterinarian. I completed my acupuncture training immediately out of vet school. I attended the Chi University that is outside of Ocala, FL. I started my chiropractic training at Parker University in Dallas, TX, which is a human chiropractic school that also offers an animal certification. I have studied with a professor at the Health Pioneer Institute near Chicago, IL, who focuses on the neurology related to chiropractic. Finally, I just completed a master’s degree in Equine Integrated Veterinary Medicine from the Chi University, which covered spinal manipulation (chiropractic), rehabilitation, pain management, and acupuncture for horses.

Q: Why is continuing your education as a veterinarian important to you?
A: I’m an education junkie. I want to help my patients as much as I can, so I enjoy always learning something new. I decided to come down to Palm Beach Equine Clinic to learn more about sports medicine. I have known Dr. Bill Patterson for a while, and he practices sports medicine related to how the whole horse moves and specifically the back and neck. I am here to work with him to learn how to combine sports medicine with the Traditional Chinese Medicine that I’ve been focused on.
Q: What benefits do you think Traditional Chinese Medicine provides for equine athletes?
A: Learning Eastern or Chinese medicine helps with paying attention to the horse as a whole being and how their environment, job, and personality can affect their health. It has taught me additional signs to watch for when examining a horse and deciding on a diagnosis. Show horses are limited in the medication they can receive for pain and discomfort, but we can offer acupuncture or massage if a horse needs some care before the competition. I have been a part of helping horses with a lameness or health care issue using Chinese medicine when Western medicine hasn’t been successful or had a good answer.

Q: How has it been living and working in Wellington so far?
A: I’m still settling into my role at PBEC, but I’m excited to be here. If someone is interested in sports medicine, working here is the dream because you get to learn about every specialty all in one place. Everyone comes to Wellington to work and learn from the best in the sport horse industry. I think this is the equestrian equivalent of moving to Los Angeles to be in the movies. I love Florida. There is so much wildlife, it’s beautiful, and I can garden in the winter!
I’ll be working seasonally at PBEC. My partner and I bought a farm in Loxahatchee, near Wellington, a year and a half ago. I still see clients in Ohio and Kentucky, so I currently go back and forth. I plan to spend most of the winter in Wellington and travel to Ohio and Kentucky in the summer to see clients.
Q: How has it been working with Dr. Patterson and the team at PBEC?
A: It’s a dream come true. I’ve learned so much from Dr. Patterson and seeing more complex cases has been really interesting. Everyone at the clinic has been helpful and friendly. I am excited to get to work with and learn from the best in the industry.
Q: What does a typical week look like for you right now?
A: I often see patients for acupuncture or chiropractic treatment at the start of the week when the horses have some downtime away from the horse show. Monday is usually my busiest day and favorite day to work. A lot of barns are closed, and the horses enjoy how quiet it is while I’m working on them.
For the rest of the week, I usually ride around with Dr. Patterson and help with lameness cases as they pop up. I am also going to cover some shifts at the horse show on weekends, which I like because I get to see my clients succeeding in the ring after I’ve helped them.
Q: What do you enjoy doing in Wellington when you’re not working?
A: I ride when I can. I also love the ocean. My partner, Steve, and I like to go offshore fishing. I also enjoy spending time with my dogs. We have a dachshund named Phoebe and a St. Bernard named Bruno, which covers both ends of the size spectrum!

Meet PBEC Veterinary Intern Dr. Claire McDonald
Dr. Claire McDonald grew up in the town of Jefferson City, Missouri. She knew from a young age that she wanted to be a veterinarian. Dr. McDonald completed her undergraduate degree in Biology at William Woods University in Fulton, Missouri where she had excellent mentorship from the university equine veterinarian, sparking her interest in equine practice. Dr. McDonald went on to complete her Doctor of Veterinary Medicine degree at the University of Missouri with Magna Cum Laude honors. Dr. McDonald began her internship at Palm Beach Equine Clinic shortly after graduation. Dr. McDonald loves the variety of caseload here at PBEC and learning about all aspects of equine practice.
Where are you from?
I am from Jefferson City, MO, which is located between St. Louis and Kansas City. You get the best sunsets here, plus all four seasons in their truest form.
Where did you go to school?
I completed my undergraduate degree in biology with a pre-veterinary focus in 2021 at William Woods University in Fulton, MO. The school was unique because it had an equestrian program with western, dressage, hunter/jumper, and saddle seat disciplines. There was no shortage of opportunities to work with and be around a wide range of horses. As part of our pre-vet curriculum, we learned equine anatomy and physiology, as well as the basics of lameness exams, dentistry, and more. It definitely sparked my initial interest in equine veterinary medicine.
From there, I attended the University of Missouri College of Veterinary Medicine, where I was fortunate to have two full years of clinical rotations rather than the standard one year at most schools. This allowed me to rotate through the small animal, farm animal, and equine areas of the hospital and broaden my knowledge.
Have you always known you wanted to be an equine veterinarian? What has your journey been like getting to this point?
From my undergraduate days to my time in veterinary school, I knew equine medicine was something I had to include in my veterinary career. I absolutely love working with these amazing creatures, spending most of the day working outside, and developing lifelong friendships with my clients. Also, there is a severe shortage of equine veterinarians in this country, and I want to help fill that need! As a horse owner, I know how incredibly valuable it is to have access to an equine veterinarian.
What does a typical day as an intern look like?
It depends on the rotation! We all rotate through medicine, surgery, ambulatory, anesthesia, and overnight. My current rotation is medicine, so my typical day starts by getting up a few hours early (sometimes as early as 5 a.m.) and checking on my patient notes from the overnight shift. From there, I go to the clinic between 6 a.m. and 7 a.m. to begin physical examinations and report my findings to the head clinician on the case.
During 8:30 a.m. rounds, we all update each other on our cases and treatment plans for the day. I then perform any necessary treatments throughout the day and update the medical record. At 5 p.m., we all round again to review the day’s activities on our cases, and we round with the overnight intern on what each patient needs overnight.
What’s your favorite part of working at PBEC?
My favorite part of working at PBEC is being able to work alongside so many other veterinarians and specialists. It allows you to get an opinion on any case you have from somebody right down the hall. Although this job can be tough at times, I definitely feel myself growing in my knowledge and confidence every day!

What’s something you hope to learn or accomplish by the end of your internship?
By the end of my internship, I hope to be equipped with the skills and knowledge needed to be a strong general equine practitioner, wherever I end up. I want to be a helpful resource in more rural areas where veterinary care is difficult to find. I also plan to stay in touch with the team at Palm Beach Equine Clinic, and I can reach out anytime I have a question.
What do you find most rewarding about working as an equine vet?
What I find most rewarding is the gratitude from clients when you show up to help their horse. There is also nothing more gratifying than seeing a horse go from being sick and in pain to happily eating and walking out of the hospital healthy. Even though this area of veterinary medicine can be physically demanding and require long hours, it is definitely worth it to me, knowing that I’m making a difference for both the horse and the owner.
What do you do in your free time?
In my free time, I love to explore, whether that involves going to the beach, visiting Disney World or the Keys, or trying out new restaurants with my intern-mates. I also enjoy running and listening to music to clear my mind.

When 17-year-old Oldenburg gelding Madison Avenue (by Madison x Olympic Ferro), known as “G6” in the barn, developed recurring fevers and concerning bloodwork in September 2025, his owner, Jennifer Chaszar, knew something wasn’t right. His primary veterinarian, Dr. John Lockamy, had been monitoring him closely at home at Lady Jean Ranch in Jupiter, FL, but as his inflammation markers climbed and his fever returned, Dr. Lockamy recommended a deeper look.
“G6 had developed a fever that returned after initial treatment, he had a low white blood cell count, and his serum amyloid A (SAA) level was elevated at 3,000 in his bloodwork,” Chaszar recalled. “Dr. Lockamy referred us to Palm Beach Equine Clinic (PBEC) because we didn’t want to overlook a more serious underlying issue.”
SAA is the major acute phase protein in horses and is produced during the acute phase response, which is a nonspecific systemic reaction to any type of tissue injury. While usually very low or close to zero, that number will rapidly and dramatically increase with a systemic infection.
A Critical Revisit
G6 was initially treated at PBEC in Wellington, FL, in 2023 when he had recurring colic symptoms. What was initially thought to be ulcers was diagnosed through gastroscopy as delayed gastric emptying by Dr. Jordan Lewis. A change in diet, with an emphasis on the portion size at each feeding, helped increase motility in his digestive tract and eliminate symptoms for a time, but those returned two years later.
G6 arrived at PBEC on September 21, 2025, where he was evaluated by internal medicine specialist Dr. Emilee Lacey and intern veterinarian Dr. Rachael Davis. G6 had been experiencing intermittent fevers, lethargy, and colic signs. An abdominal ultrasound soon revealed a left dorsal displacement of his large colon, which thankfully resolved with supportive care.
However, his bloodwork told a more complicated story. With inflammation still present, the PBEC team performed a gastroscopy to visualize the stomach lining. “The gastroscopy showed a few ulcerations of the squamous mucosa of the stomach and a nodular mass in the pyloric region,” said Dr. Davis. “The duodenum (first part of the small intestine) was mottled in appearance. Biopsy samples from both the pyloric mass and the duodenum were collected and submitted for histopathological analysis, which revealed evidence of inflammatory bowel disease.”
Chaszar remembered the relief she felt when the biopsy results returned. “The biopsies came back negative for malignancy,” she reported. “There was no evidence of cancer — just inflammatory changes. That provided tremendous relief and allowed us to focus on healing and recovery.”
G6 remained bright, cooperative, and comfortable during his stay, a testament to the attentive nursing and veterinary care he received.
Healing at Home
Dr. Lacey prescribed a thoughtful treatment plan that included gastroprotectants, dietary changes, and careful monitoring at home.
“Due to his known diagnosis of delayed gastric emptying and the suspicion of inflammatory bowel disease (IBD), we recommended trialing a diet that excluded wheat and his known allergies of corn, oats, rice bran, and carrots,” explained Dr. Lacey. “IBD has been loosely associated with gluten intolerance (wheat) in horses.”
Back home, Chaszar followed PBEC’s instructions closely to help support G6’s recovery. “His diet was modified to include softer, easily digestible forage and smaller, more frequent meals,” she noted. “I monitored his temperature, appetite, and demeanor every day to be sure he was progressing.”
Dr. Lacey and Dr. Davis also stressed the importance of daily exercise to promote normal gastrointestinal motility, hydration, and close communication with the veterinary team. They also wanted to see G6 back in 30 days for an examination.

A Promising Recheck
Exactly one month later, G6 returned to PBEC for a scheduled recheck gastroscopy. Chaszar described this visit as a hopeful milestone. “His second visit was a one-day appointment designed to see how the pyloric nodule and inflammation had responded to treatment,” she said.
The news could not have been better. Dr. Lacey reported that the previously seen ulceration had completely resolved, and the pyloric nodule had reduced by about 75%, indicating that the treatment plan was working.
With that progress confirmed, G6 discontinued the gastroprotectants and continued with supportive nutrition and management. “It was wonderful to see that improvement,” said Chaszar. “His appetite has returned to normal, and his energy is strong. G6 is back to acting like a four-year-old! When I lead him to the arena, he nickers under his breath and then shows me the Spanish walk and downward dog tricks that he does before we move on to the serious part of work.”
A Testament to Exceptional Care
Chaszar credits PBEC’s team not only for their medical expertise but also for the warmth and professionalism that defined every interaction. “The entire PBEC team, from the front desk to the technicians, nurses, interns, and veterinarians, has been exceptional,” she shared. “They are proactive and collaborative in their approach, and their compassion, communication, and attention to detail are truly remarkable.”
She added that PBEC’s dedication sets the standard for equine veterinary medicine in South Florida. “Seeing G6 healthy, thriving, and back to himself reminds me of the incredible work PBEC does every day. I am especially grateful to Dr. Lacey and Dr. Davis for their thoroughness and dedication throughout his journey.”
Why Owners Trust Palm Beach Equine Clinic
For Chaszar, the most valuable part of the experience was PBEC’s collaborative, transparent approach. “Every veterinarian and staff member took the time to explain each step,” she said. “They even shared images from his scopes so I could fully understand his care. Their organization, genuine care, and follow-up are second to none. I am deeply thankful for their continued support.”
G6 is back to his regular routine, and his recovery journey highlights not only his resilience but also the power of skilled veterinary care and commitment to excellence.
Horse owners seeking a clinic that blends top-tier medicine with genuine empathy will find exactly that at Palm Beach Equine Clinic. G6’s story stands as one more shining example of the exceptional work they do every day.

Meet PBEC Veterinary Intern, Dr. Emma Newell, Palm Beach Equine Clinic’s New Internal Medicine Specialist
Dr. Newell earned her veterinary degree from the Royal Veterinary College in 2025 after completing her Animal Science (Pre-Vet) studies at Auburn University, where she graduated Summa Cum Laude in 2021. Growing up in the hunter/jumper community in Connecticut inspired her lifelong passion for equine health and her interest in sports medicine. She is dedicated to advancing her clinical skills and providing high-quality care to equine patients.
Outside of work, Dr. Newell enjoys staying active and returning to Connecticut whenever possible to spend time with her horse.
What has been your journey to becoming an equine veterinarian?
I grew up in the hunter/jumper industry, primarily showing ponies, and that’s where I discovered my passion for sports medicine. I attended an agricultural high school in Connecticut, where I was able to major in equine sciences. That experience drove me to study at Auburn University for my undergrad, majoring in animal science on the pre-veterinary track. I graduated Summa Cum Laude in 2021, and, from there, moved to London for school at the Royal Veterinary College. Being from Connecticut, and then moving down to Alabama, I got to see the differences in the horse industry throughout the country, and I wanted to take it to an international level.
What was it like adjusting to life in the United Kingdom, and what differences did you notice in veterinary medicine there versus the United States?
I had experienced London in earlier stages of my life, so the transition wasn’t hard for me. I loved the lifestyle and living over there. The horse care and equestrian community in the U.K. are both so strong that attending that school was a great decision for me.
I think some of our methods of treating sport horses are very different, like how we view the use of antimicrobials and medications. Having that perspective when treating sport horses here in the U.S. is important because it provides insight into the veterinary care they received overseas before being imported.

What interests you most about sports medicine?
I love performing lameness exams, and I love providing care to equine athletes. When I was showing, I was very driven, so bringing that mindset to veterinary medicine and seeing patients able to perform at the top level really motivates me.
What was the process for applying to become a PBEC intern?
The process includes completing an externship at PBEC, submitting your paperwork — which consists of your CV and letters of reference — and then participating in the interview phase.
What responsibilities does an intern have at PBEC?
As an intern, you do two-week rotations throughout the hospital. Rotations include anesthesia, surgery, ambulatory, and overnights, giving you experience working in all different environments, from surgical cases to in-depth internal medicine cases. During the anesthesia rotation, you are solely in charge of providing anesthesia to patients, whether that’s standing or general anesthesia for surgical patients – that’s quite interesting. For the surgery rotation, you are responsible for patient care in the hospital prior to and post-op, and you get subbed to scrub into surgeries. Ambulatory is my favorite rotation, and you’re on the road with vets who primarily provide ambulatory care, which is a great experience.
What’s it been like working with the team and the other interns at PBEC?
The team at Palm Beach Equine Clinic was something I was really excited about coming into this internship. We have a great, well-rounded group of veterinarians with diverse experiences and passions, which allows us to learn different things from each person. It’s the same with our intern team; we’re all well-rounded and have different strengths, and I think that that really pushes me as an individual to grow.
What advice would you give to students interested in equine veterinary medicine?
Take every chance to get hands-on experience. Put yourself out there and look for opportunities to learn under different equine veterinarians. Everyone has different life experiences and points of view, which is essential to making you into a well-rounded vet. As we all know, the horse world is quite small, so building connections throughout the community is definitely something that will help you.
The Last Leg of International Travel: CEM Quarantine

Whether returning home after a thrilling summer competing on the European circuits, traveling from a home base abroad, or importing a newly purchased equine, every horse entering the United States must follow specific guidelines based on the country of origin. Once the horse “clears customs” at the airport, satisfying United States Department of Agriculture (USDA) import requirements, there’s one more thing owners must consider before their horse reaches its final destination.
Mares and stallions remaining in the United States beyond the temporary stay period must undergo additional quarantine for Contagious Equine Metritis (CEM). This sexually transmitted bacterial infection can cause infertility in mares and is carried by stallions. While endemic in Europe, the disease is not currently in the U.S., so testing and quarantine for horses entering the country from areas with confirmed cases are essential to maintain that disease-free status.
Fortunately for horses traveling to Florida, Palm Beach Equine Clinic’s Dr. Jordan Lewis works closely with Richard Faver at Ossian Ventures, one of the largest commercial CEM quarantine facilities in Florida, to oversee and conduct the rigorous testing process, which differs based on whether the animal is a mare or stallion.
“Mares are usually with us for about 15 days. They need three sets of negative cultures, 72 hours apart, and then five days of washing with chlorhexidine and applying silver sulfadiazine as a topical treatment, which we call ‘clean and pack,’” explained Dr. Lewis, adding that they take samples from three areas of the mare and also pull a blood test, called a complement fixation (CF). The CF results and each set of cultures must be sent by mail to a lab for testing, and turnaround times are about a week for the cultures and a few days for the blood.
“Stallions are a little different,” continued Dr. Lewis, noting that their process takes about 35 days. Within the first few days, a culture is taken from the stallion and sent for testing.
“When the culture comes back negative, we have a set of mares called test mares that are cycled and ready to breed,” she said. “Those stallions live cover two test mares, which then start getting cultured on day three post-breeding. They go through the same process as the other mares: three sets of cultures, 72 hours apart. Twenty-one days after breeding, they do the CF test on those mares.”
Dr. Lewis noted that the test mares undergo a process called “short cycling” to ensure they will not become pregnant from these breedings. Each stallion also receives a clean and pack treatment after breeding and can then be released once all testing returns negative.
Throughout the horse’s stay at Ossian Ventures, Dr. Lewis and other Palm Beach Equine Clinic veterinarians are available to provide any additional care the animal might need after its long journey, including Coggins testing, if necessary, in preparation for the next step in the horse’s travel plans. Owners are welcome to visit and ride during this time, given that horses are kept from interacting, and any equipment that touches the animal stays at the facility and is only used on that horse.
“I just enjoy being part of the process,” shared Dr. Lewis about her role in maintaining the health and safety of the horses in quarantine. “Plus, we certainly get to see some world-class horses coming through, which is fun.”
There are many factors to consider when traveling internationally with horses, but the Palm Beach Equine Clinic is dedicated to providing quality care at every step, from touchdown at the airport to quarantine and beyond.

Learn More About Dr. Emilee Lacey, Palm Beach Equine Clinic’s New Internal Medicine Specialist
Dr. Emilee Lacey grew up in California, graduated from the University of Pennsylvania in 2021, and completed an internship at Sports Medicine Associates of Chester County in Cochranville, PA. She has been immersed in the sport horse world her entire life, but her passion for managing fevers, respiratory disorders, and neurologic disease led her away from lameness exams and toward internal medicine. Dr. Lacey completed her large animal internal medicine residency and obtained a Master’s of Science in Biomedical and Veterinary Sciences at Virginia Tech in Blacksburg, VA, this summer. She joined Palm Beach Equine Clinic in August 2025.
What first sparked your love of horses?
My love for horses started at a very young age, but it was really nurtured by my horse-loving grandmother, aunt, and mom. After what felt like years of begging, my mom finally put me in horseback riding lessons when I was in grade school. After about a year of consistent riding, I convinced my mom to let us buy my aunt’s horse, Chili, an off-the-track Thoroughbred (OTTB) that was barely restarted and literally lived across the country in Maryland. She came off the trailer in California like a typical green OTTB: head straight up in the air, nostrils flared, and breathing like a dragon. I was only seven years old at the time, and I thought this was the BEST DAY EVER. My trainer had very different thoughts. This mare not only taught me to ride; she also taught me valuable horsemanship skills I still utilize today. Many other horses have come after Chili, but this mare will always be the spark that truly ignited my love for horses.
What inspired you to become a large animal veterinarian?
I’ve known I wanted to be a veterinarian since I was three years old. I halfheartedly joke that the words “I want to be a vet” were actually my first coherent words. I spent my childhood years obsessed with every TV show or movie that even slightly mentioned veterinary medicine, earned every Girl Scout patch remotely related to veterinary medicine or animals, and volunteered as much time as I could in any clinic or with any equine veterinarian that would take me.
When I finally made it to veterinary school, I was convinced I had to be a small animal veterinarian to have time for my own horses. I was so wrong! During my studies at the University of Pennsylvania, I met many vets who had their own horses and hobbies while maintaining an excellent work-life balance. I also realized that not only was I more interested in large animal medicine, but I was also better at it because I could connect with the owners. I am a horse owner first, and a veterinarian second. I understand how these special animals can become a part of your family.
After veterinary school, I completed an internship with Sports Medicine Associates of Chester County in Pennsylvania. I developed a special interest in managing poor performance that is not related to lameness. Diseases like Equine Asthma, myofibrillar myopathy, gastric ulceration, chronic hepatopathy, and heart murmurs all pulled me away from lameness exams and toward internal medicine. After my internship, I was humbled and honored to complete a large animal internal medicine residency at the Virginia-Maryland College of Veterinary Medicine in Blacksburg, VA. This three-year-long opportunity was a lot of hard work, but I loved every minute. When you love what you do, it doesn’t feel like work. I truly have the best job in the world!

How did that path lead you to Palm Beach Equine Clinic?
I found my way to Palm Beach Equine Clinic through a few mutual patients while completing my residency in Internal Medicine at Virginia Tech. While caring for these patients in the hospital, I was collaborating with [PBEC Founder] Dr. Paul Wollenman almost daily for a few weeks. During this time, [PBEC President] Dr. Scott Swerdlin reached out to me to gauge my interest in a job opportunity with PBEC. I was so impressed with the communication and collaboration among the veterinarians at this hospital, but what really convinced me was their dedication to excellent patient care. At PBEC, care doesn’t stop when an animal is discharged. The veterinarians here will continue to check in on your horse long after they’ve returned to the barn, and there’s also a team of other veterinarians, technicians, and support staff ready to help you if needed.
What are your current responsibilities or areas of focus at PBEC?
My current area of focus at PBEC is equine internal medicine. This is a specialized branch of veterinary medicine that focuses on the diagnosing and treating diseases affecting internal organ systems, including the heart, lungs, gastrointestinal tract, kidneys, liver, endocrine system, central nervous system, and others. I primarily care for patients in the hospital that require intensive care, but I also dedicate time to recheck examinations and consultations in the field. I tell my friends and family that my job is similar to a human physician working in an intensive care unit in a hospital.
What does a typical day on the job look like for you?
A typical day starts with morning rounds with our associate veterinarians, surgeons, and intern veterinarians to review the status of our current inpatients and update their treatment plans. After rounds, I review any completed daily bloodwork and complete any pending diagnostics, like recheck ultrasound examinations or a gastroscopy, for the current inpatients. I might spend the afternoon at nearby farms completing recheck examinations on previous patients, consulting on new cases from other veterinarians, or conducting an outpatient appointment in the hospital. I am also available for incoming emergency admissions, which can happen quite frequently and without much notice! At the end of every day, I round again with our intern veterinarians, which ensures excellent patient care in a collaborative environment.
What do you enjoy most about being part of the PBEC team?
My favorite part of working at PBEC is the ability to collaborate openly with veterinarians of different specialties and backgrounds. A person simply cannot know everything, and there is always more than one right way to do something. It’s really special to be able to walk down a hallway and talk to three different surgeons about their experiences with a certain diagnosis!
What new technology or recent advancements in veterinary medicine do you find most exciting?
I am most excited about recent advancements in therapeutic options for the management of equine metabolic disease (EMS). EMS is a common endocrine disorder associated with a horse’s inability to regulate their insulin levels – similar to “pre-diabetes” in humans. Horses with EMS are at high risk of developing laminitis, which can be life threatening. Historically, EMS was only managed with dietary changes and the limited efficacy of a short list of medications.
Now with the current use of ertugliflozin, a medication belonging to a class of drugs called sodium-glucose cotransporter 2 (SGLT2) inhibitors, we have another option to reduce a horse’s insulin level in an attempt to prevent laminitis. Further studies are needed regarding long-term use, but we have seen some promising results over the last few years in clinical practice. As a horse owner who lost her heart horse to laminitis, it is really rewarding to help horses who suffer from this condition now.
What’s the most challenging part of being an equine veterinarian, and how do you handle it?
The most challenging part of being an equine veterinarian is convincing young, aspiring veterinarians to join our field! We are facing a national crisis due to the shortage of large animal veterinarians. More newly graduated veterinarians are entering small animal practice, there is an increased rate of early-career equine veterinarians leaving the profession, and a significant number of equine veterinarians are nearing retirement. One of my goals as an equine veterinarian is to show the younger generation that this is the best job in the world. I try to create a welcoming environment for learning by hosting externs and teaching interns every chance I can get. We need more horse vets!
What’s the most rewarding part about serving the equestrian community?
The most rewarding part of serving the equestrian community is having the opportunity to give back to the community that gave me so much growing up. I was so blessed to be surrounded by such thoughtful and caring horse trainers, owners, and veterinarians who cared for me like I was family. I was raised in the horse world, and it’s surreal and humbling to be able to care for these special animals during their most vulnerable times. I hope I never have to meet you and your horse in the hospital during an emergency, but if I do, I understand what it’s like to be the emotional owner! I’m here to care for your horse and support you in whatever decisions we need to make for them.
Is there a particular case or experience you’ve had at PBEC that has been especially meaningful to you?
My first few weeks at PBEC have been filled with some unusual cases, but one pony in particular has gained a special place in my heart. This pony was sick for a few days before being admitted to the hospital. Upon initial examination, I diagnosed an intra-abdominal mass. Through aggressive supportive care as well as anti-inflammatory and antibiotic medicines, this mass has decreased substantially in size, and the pony was able to go home. This pony went from being dull and not eating to being very difficult to catch and developing a voracious appetite. I recently received a video of him playing in a sprinkler at home. Success stories like this remind me of why I chose to pursue this career.
What advice would you share with those who dream of becoming equine veterinarians one day?
To those horse-crazy girls and boys thinking of being an equine veterinarian, don’t give up on your dream! Take every opportunity you can to be around horses, and network with any veterinarian you can. Be brave and introduce yourself – most of us love to chat about this job. If you find yourself in Florida, don’t hesitate to contact PBEC to set up an externship. We need you to join our profession!

When you’re not at work, what do you enjoy doing to relax and recharge?
When I’m not at work, you can catch me riding my horse, William, a 16-year-old OTTB gelding who has had me wrapped around his hoof since he was three years old. I have had this horse just a few months longer than I have known my husband, Mike. When I’m not at the barn, Mike and I enjoy walking our dogs on the beach, scuba diving, or simply enjoying a sunny afternoon at the pool with our family. It’s so important to have an identity outside of being a veterinarian, and I aim to be that example!

Where are you from?
I was born and raised in Switzerland, where we speak four national languages —German, French, Italian, and Romansh (an old Swiss tongue that’s still hanging on). I’m from Geneva, which is in the French-speaking part of the country and the best Swiss
city in my humble opinion.
Where did you earn your degree?
In Switzerland, you can only earn a veterinary degree in the German-speaking part. When I was just four years old, I asked my mom if it was possible to have a vocation because I already felt like mine was becoming a veterinarian. Thanks to my parents’
unwavering support, I was able to attend a bilingual school to learn German properly. I eventually studied veterinary medicine at the University of Zurich, which is in the largest city in Switzerland. Back home, veterinary school is structured into a three-year
Bachelor’s program followed by a two-year Master’s. After completing both, we take the federal veterinary licensing exam to become fully qualified.
What is your background with horses?
I started riding when I was three years old and later competed in show jumping for almost 10 years. I had to pause during vet school, but horses have always remained the love of my life. I used to say that my passion wasn’t actually show jumping — it was
taking care of my horses, spending time with them, and getting to know them like my own friends.

What brought you to PBEC?
I did a four-week externship at PBEC about two and a half years ago and was absolutely starstruck by the level of equine medicine practiced here. The variety of disciplines and cases, combined with the opportunity to learn new ways of practicing,
made me determined to come back.
I love sports medicine, and here you get to see everything — dressage, show jumping, polo, barrel racing, bucking horses, pleasure horses, and even Thoroughbreds. Each discipline brings its own veterinary challenges, and that variety is what makes PBEC so exciting. The clinic’s facilities and the range of specialties, from sports medicine and internal medicine to reproduction and ophthalmology, make it an incredible place to learn. Also, doing an internship in a private clinic rather than a university allows me to practice more hands-on medicine and grow more confident and independent in my clinical decision-making.
What was the process of becoming an intern?
Honestly, it was easier than I expected, thanks to the amazing support from Dr. Swerdlin and his team. I filled out a couple of forms, submitted some documents, made a quick visit to the U.S. Embassy in Switzerland, and I was good to go. They really made the whole process smooth and stress-free. Once I arrived, I had to schedule an appointment to get a Social Security number.
As an international intern, I was a bit worried about housing and transportation, but the clinic has everything well thought out. We’re provided with free housing in a lovely house surrounded by nature, and the company also offers cars for international interns who can’t purchase one at the time of arrival. PBEC really ensures we have great living conditions so that we can fully focus our energy on the internship.
What is the program like so far?
It’s definitely challenging — not just the workload but also being so far from my family and friends for the first time, adjusting to a new environment and the working world, as well as figuring out how to be the kind of veterinarian I want to become. It’s not always easy —internships aren’t for everyone — but I’m adapting.
My colleagues and supervisors have been incredibly supportive, and that makes a huge difference. This program exposes me to every corner of equine medicine, helping me decide what path I want to pursue in my career. And I get to learn from some of the
most experienced and generous equine vets out there.

What is a typical day like for you?
I usually get to the clinic around 6 and 7 a.m. to check on my patients and write their SOAPs (notes that stand for Subjective, Objective, Assessment, and Plan). At 8:30 a.m., we have morning rounds with the surgical resident and clinicians where we go
over every patient, update their plans, and ask questions to better understand the cases.
After rounds, depending on my rotation, I might scrub into surgery, run anesthesia, or take in emergency cases. If I have a quieter moment, I’ll research my cases to deepen my understanding or help with outpatient procedures. I also just enjoy spending time
with the patients.
At 5:30 p.m., we do rounds with the overnight intern, who stays at the clinic until midnight (or later, depending on the case load) and is then on call until 8 a.m. One of the day interns is also on call for anesthesia each day.
What is something new that you’ve learned?
So much, and it’s only been a month. I can now confidently run general anesthesia, place arterial and venous catheters, perform abdominocentesis, and do a flash ultrasound. I even got to inject a coffin joint! I’ve also spent time in the reproduction
department and can now perform transrectal ultrasounds of the mare’s reproductive tract, do uterine flushes and infusions, and place urinary catheters. The list keeps growing, and I’m so grateful for the learning opportunities.
What do you do in your free time?
I brought my dog, Pepper, with me, so we spend time at the beach in Palm Beach or Jupiter, run around the neighborhood, or go to the dog park. In the evenings or on weekends, I read and re-read Harry Potter.
I’ve also discovered the wonders of Target, Whole Foods, and the mall… I may or may not have spent at least 24 hours there already.
And of course, I call my boyfriend… who patiently listens to me talk about transrectal ultrasounds while wondering where his life took a very specific turn.

If you have a performance mare that you wish to breed without interrupting her career, embryo transfer is a viable option. Palm Beach Equine Clinic (PBEC) in Wellington, FL, offers an extensive range of assisted and advanced reproductive procedures, including embryo transfer. With spring fast approaching, now is the time to plan.

PBEC President Dr. Scott Swerdlin highlights the advantages of the embryo transfer process, which has been utilized since the 1970s. This method is especially beneficial for sport horse mares that cannot afford to take time off for pregnancy. By using embryo transfer, you can continue riding your best mare while simultaneously breeding for your future champions. Additionally, embryo transfer is a viable option for mares with high genetic merit who cannot carry a foal. Some mares may have orthopedic issues that would be exacerbated by the extra weight of pregnancy, while others may have significant reproductive challenges, such as chronic uterine infections or a fibrotic uterus, which hinder their ability to conceive or support a developing pregnancy.
The first step in the embryo transfer process is embryo production. For this article, we are focusing on traditional in vivo embryo production vs in vitro embryo production. In vivo embryo production requires the donor mare to be bred, conceive, and produce an embryo that can then be transferred to a recipient mare. This necessitates the mare being off any hormones like Regumate® (altrenogest) or long-acting progesterone as they suppress the mare’s estrus cycle.

Strategic breeding management is essential to minimize disruptions to a mare’s training and competition schedule. This may include hormonal manipulation of the mare’s reproductive cycle, a series of reproductive examinations performed using transrectal palpation and ultrasound, a uterine culture and cytology, and breeding the mare by artificial insemination or via natural cover. It is also crucial to document the day and time of ovulation. Whether using fresh, cool-shipped, or frozen-thawed semen, the day and time of ovulation need to be documented to plan for the second and third steps of the process: embryo flush and transfer.
“Knowing the day of ovulation is important,” explained Dr. Swerdlin. “In the mare, fertilization and conception occur in the oviduct, where an embryo will remain for approximately 6 to 6.5 days before migrating to the uterus. Not knowing the day of ovulation might mean that the embryo is still in the oviduct at the time of the uterine flush. Conversely, if the embryo is further along in development, it becomes larger and more fragile, which decreases the chances of a successful outcome.”

To minimize disruptions to the mare’s schedule, most of the process can be performed on-farm, or owners can elect to come to PBEC on an outpatient basis. Veterinarians will closely monitor the mare’s estrus cycle to determine the optimum time for breeding, maximizing the chance of achieving a pregnancy.
“To improve our chance for success, once we determine that the mare is ready, the dominant pre-ovulatory follicle is stimulated to release the oocyte (egg) by administering an ovulatory agent,” stated Dr. Swerdlin. “This ovulatory agent mimics the mare’s naturally occurring hormonal process, and when used appropriately, the majority of mares will ovulate within 24 to 48 hours post-administration.
“Timing the insemination in relation to ovulation is key to success,” he continued. “This is especially true when using frozen semen. For mares that will be inseminated with frozen-thawed semen, we suggest that they arrive at the clinic the same day that the ovulatory agent is administered. This ensures that we can inseminate the mare as close to the point of ovulation as possible.”



The next step is embryo recovery, which is performed 6.5 to 8 days post-ovulation. “The mare will come to the clinic, and the process takes about an hour,” said Dr. Swerdlin. “During this procedure, the donor mare’s uterus is flushed with several liters of embryo flush media. This fluid is recovered and filtered through a special embryo filter to capture the embryo.”
After the embryo is retrieved, it is washed and graded to determine embryo quality. Embryos are graded on a 4-point scale, which 1 indicating excellent quality and 4 indicating a degenerate or dead embryo. Finally, the embryo is prepared for either direct transfer into a recipient mare, shipment to a recipient herd, or frozen for future use.
The final step in the process is the embryo transfer, which requires careful coordination. The success of this procedure is heavily dependent on selecting a suitable recipient mare, taking into account factors such as the mare’s age, size, maternal behavior, synchronization, and overall reproductive health.

“Owners can provide their own recipient mare, but we often recommend that mare owners utilize a leased recipient mare,” noted Dr. Swerdlin. “Numerous recipient herds are located throughout the country, with the closest ones being in the Ocala area. Currently, recipient mares are in very high demand, and each herd has a limited number of contracts available per year. One key advantage of using a recipient herd is that it allows multiple mares to be synchronized to match your individual mare’s ovulation date rather than relying on a single client-owned recipient. For those who prefer to use their own mare, our reproductive specialists at PBEC can manage the synchronization of the recipient mare and perform the embryo transfer.”
The embryo transfer procedure takes place at the clinic. The recipient mare is gently restrained in stocks with the aid of mild sedation. The embryo is carefully loaded into a transfer gun, which is guided trans-cervically into the mare’s uterus. Once the position has been confirmed, the embryo is deposited into the base of the uterine horn. A reproductive ultrasound is performed between three to seven days afterward to assess the uterine environment and confirm that the embryo is developing properly. Recipient herds will often report pregnancies between day seven to nine after transfer.

Dr. Swerdlin noted that the success rate for embryo recovery varies based on the type of semen used and the donor mare. “When using fresh and cool-shipped semen, embryo production rates can reach between 70% and 90%,” he said. “With frozen-thawed semen, the rates are lower, ranging from 50% to 60%. Overall, the success rate of the embryo transfer ranges from 70% to 90%, depending on the quality of both the recipient mare and the embryo.”
Embryo transfer provides an effective and practical solution for sport horse owners and breeders. As the demand for top sport horses increases, it continues to be a valuable tool for those looking to breed that special mare.
