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.

Equine ulcers have long been a common concern for horse owners. Our understanding of ulcers has dramatically improved over time through medical advancement, and there is currently more nuance to the diagnostics, treatment, and management of horses suffering from these internal sores. Gastroscopy and ultrasound have become more readily available, and their increased accessibility have allowed non-specialty practitioners more experience and a greater comfort level with these tools. These developments throughout the industry have led to more animals being correctly diagnosed and appropriately treated.
Jordan Lewis, DVM of Palm Beach Equine Clinic (PBEC) sees a variety of equine ulcer cases. She breaks them down into three categories: gastric ulcer disease of the squamous mucosa, gastric ulceration of the glandular mucosa, and colon ulcers of the right dorsal colon.
Equine gastric ulcer disease of the squamous mucosa refers to the ulcers found on the stomach’s inner lining closer to the esophagus. They are primarily caused by exposure to stomach acid and vary in severity depending on the amount of time the stomach’s lining has been in contact with the stomach acid.
“We often see this increased stomach acid exposure with the squamous mucosa in performance horses due to the mechanical aspects of exercise and abdominal pressure,” Dr. Lewis described. “The increase in acid production and contact time can also be seen in fasting animals and animals with delayed gastric emptying or slowed motility.”
Glandular mucosa describes the stomach lining around the pyloric region closer to the intestines. Ulcers found here are typically caused by a decrease in mucosal blood-flow as well as a decrease in mucus production, which normally serves as a protective barrier for the stomach lining. Stress and non-steroidal anti-inflammatory drugs (NSAIDS) such as phenylbutazone (“bute”) or flunixin meglumine (“Banamine®”) are the usual culprits in this case.
Similarly, ulcers found in the colon are also usually caused by stress and NSAID administration, leading to a decrease in the mucosal wall protection resulting in ulceration and inflammation.
“In some cases with colon ulcers of the right dorsal colon, we see minimal thickening noted on the right abdominal wall, but other times it can be more severe thickening with more ominous clinical signs of colic, fever, hypoalbuminemia (protein loss), ventral and limb edema, and diarrhea,” detailed Dr. Lewis.
The tricky thing about ulcers is that they do not always present with the same symptoms in every horse. It can be difficult to know when it’s time to be a little more invasive in order to take a closer look at a horse’s digestive system. At a minimum, persistent symptoms warrant a veterinarian consultation.
“The range of symptoms can vary from mild to severe,” Dr. Lewis explained. “The horse might be being a picky eater, or they might exhibit moderate to severe colic symptoms like signs of abdominal discomfort such as pawing or rolling. Even still, some horses present with the only outward sign being poor performance.”
Dr. Lewis uses varying diagnostic tools for a complete understanding of the affliction. Sometimes she will perform the Succeed test, which is a fecal test that generally helps indicate the presence of ulcers. Another option is to perform a gastroscopy with a three-meter endoscope to see the stomach where both forms of gastric ulcers are found. Ultrasound is the primary diagnostic tool to look for thickening of the right dorsal colon wall indicating ulceration in the colon. Basic bloodwork to determine total albumin, a protein made by the liver, also helps indicate more severe cases of colon ulcers.
Once a horse has been diagnosed with ulcers of any variety it’s important to begin treatment, especially since horses suffering from ulcers are predisposed to colic. Because each type of ulcer disease has a different underlying cause, the treatment protocol and medications are also different.
Though omeprazole paste used to be thought of as the cure-all, today we know that it is only part of the puzzle. Dr. Lewis recommends an omeprazole paste for at least a four-week period and uses other medications in conjunction with this depending on what type of ulcer she is treating. For horses that have ulcers of the squamous mucosa experiencing more severe, colic-like symptoms, Dr. Lewis adds a dose of sucralfate before meals to the protocol. If she finds ulcers in the glandular and pyloric region of the stomach, misoprostol and prostaglandin analog is used. For ulcers of the right dorsal colon, sucralfate is used as a coating agent while misoprostol is used as a treatment.
In addition to medication, some lifestyle adjustments can aid in maintaining an ulcer-free digestive tract. “It’s helpful if we can provide a more natural, less stressful environment for these horses with continuous grazing on pasture or hay as well as more turnout,” stated Dr. Lewis.
She continued, “Horses with gastric ulcers do well on adding alfalfa hay as a buffering agent before a grain meal, while horses with colon ulcers do well on a low-bulk diet, meaning less forage and a more complete feed-based pellet. Adding a psyllium-based supplement can be helpful for these horses too.”
Even with the best curative efforts, some horses can continue to suffer from ulcers, underscoring the importance of monitoring your horse for any changes even after treatment. Because sport horses have an increased likelihood of developing gastric ulcers due to exercise, their constant work also increases the odds of them have recurring ulcers. Personality and demeanor also play a part.
“Horses that have recurrent ulcer disease tend to be horses that internalize more and are stressed easily,” said Dr. Lewis.
She highlighted some additional measures that can be taken to help continuously protect the stomach’s lining, noting the importance of a regulated diet and more opportunity to relax, as well as treatment with a prophylactic dose of omeprazole paste.
If you think your horse feels a little off from their normal behavior, it might be time to discuss different diagnostic options with your veterinarian. Trust your gut – it might just help your horse’s too.
