Graduating in 1987 from Tuft’s University School of Veterinary Medicine, Dr. Parrott opened his own practice four years later in 1991.

Our clinic is located at Black Oak Stables, South Hamilton, MA, and includes stabling for hospital cases, examination room, indoor arena, and outdoor round pen for in-depth diagnostics and progressive treatments for equine lameness. 

Dr. Parrott’s passion for horses began at a young age at a farm in Rockport, MA where he started riding and caring for horses, cows and other farm animals. Dr. Parrott enjoys spending time with his family, riding his horses and playing polo.
