Dr. Jonathan Leach V.M.D.

Dr. Leach’s family holds a legacy of keeping animal companions healthy since 1933, when his father began his practice as the first veterinarian on Cape Cod. While observing his father throughout childhood, Dr. Leach nurtured a natural talent and his love for vet medicine. He attended Ohio Wesleyan University for his undergraduate degree. Then he studied reproductive physiology at the University of Massachusetts before attending University of Pennsylvania, where he earned his VMD. Since then he has gained both clinical expertise in a hospital setting and field experience at racetracks, even serving as a veterinarian for a Kentucky Derby horse in 1984. He loves treating all conditions, but his special interests include cruciate surgery, chronic ear conditions, and lameness in geriatric patients. Dr. Leach has practiced both equine and small animal medicine for three decades and is very proud to offer quality care from a family practice on Cape Cod. He now lives in Marstons Mills with his family and pets, all of whom have a unique role in helping to develop and operate Leach Animal Hospital.
