After graduating from Tufts in 1991, Dr. Reilly set off to work on the East coast horse racing circuit with Dr. Richard Kester. He spent time working in the New York/New Jersey area and winters in southern Florida. He then moved on to work at Delaware Park, before landing on Cape Cod where he ultimately established a large animal ambulatory practice in 1995. After watching the racetracks in Massachusetts close in 1997, he combined his equine practice with a small animal practice, forming Mid-Cape Animal Hospital. For the next 8 years, Dr. Reilly traveled to Nantucket, Martha’s Vineyard, Cape Cod, and southeastern Massachusetts for farm calls throughout most of the year. Winters were spent in Florida working on young racehorses in training, as well as on horses competing at the Wellington Equestrian Festival. After a few years of searching for a location to establish an equine hospital, construction began in the spring of 2005 in Plympton. The South Shore Equine Clinic & Diagnostic Center opened its doors in January 2006.

Dr. Reilly is certified as a Diplomate by the American Board of Veterinary Practitioners (ABVP) specializing in Equine Practice. ABVP Diplomate status is granted under the approval of the American Board of Veterinary Specialties, an official committee of the American Veterinary Medical Association. While other veterinary specialties focus on specific disciplines or organ systems (e.g. ophthalmology, cardiology, etc.), ABVP diplomates demonstrate excellence in all areas of specialty care of the total patient. Currently there are less than 100 veterinarians that are certified Equine ABVP diplomates in the Unites States, including Dr. Reilly. He is the only ABVP certified equine private practitioner in New England.

Dr. Reilly has spent over 25 years working on competitive horses of all disciplines. He has worked on numerous Thoroughbred and Standardbred racehorses; some of which have competed and won in the Kentucky Derby (Fusaichi Pegasus, Saarland); the breeder’s cup (Beautiful Pleasure, Storm Flag Flying); and the Hambletonian (Royalty for LIfe, Wings of Royalty).

Caitlin E. Owen, MVB&S, MRCVS

Dr. Caitlin Owen grew up riding ponies through the woods in her hometown of Groton, Massachusetts. She considers West Barnstable a second home though as she spent much of her childhood visiting family there. As a kid she vaulted, rode dressage, was in 4-H, worked in a dressage barn and went on fun adventures with her ponies. After rehabilitating her Thoroughbred mare from a long illness with EPM, Caitlin first consciously considered becoming a veterinarian. Fifteen years later and she still has that (now thirty-one year old) mare! On her road to becoming a vet Caitlin attended the University of Massachusetts, Amherst, where she obtained a bachelors degree in animal science. While at UMass, she studied abroad in the west of Ireland where she rode lots of cool horses and fell in love with the country. When it came time to choose a veterinary school, Europe was calling. Caitlin completed her veterinary degree at the Royal (Dick) School of Veterinary Studies in beautiful Edinburgh, Scotland. As a vet student Caitlin got to travel and learn from equine clinicians all over the USA, the UK, Ireland and Denmark. South Shore Equine Clinic was one of the places she visited an extern and that experience clearly left a good impression! After graduation she was again drawn across the Atlantic to Ireland, where this time she completed an equine hospital internship in the heart of Thoroughbred racing country.


Caitlin E. Owen Caitlin is excited to be working back home in Massachusetts now at South Shore Equine Clinic. She is looking forward to getting more involved with ambulatory work and getting to know the horses and people of the south shore! Caitlin’s primary veterinary interests include foals, imaging, colic, and generally keeping horses happy and healthy! Outside of work she likes to traveling and spending time with her horses, family and friends. She’s extra excited to live so close to the ocean and hopes to find a little time this summer to get a spot of surfing in!
