Owned by the veterinarians who care for your pets.
This hospital is part of Symbios Animal Health, a family of six New Jersey practices owned by working veterinarians. They live in these communities, they practice in these hospitals, and they answer to the families in their exam rooms, not to investors. That is what 100% family owned means.

Dr. Nick Pope Co-owner · Symbios Animal Health Nick grew up on an Oklahoma farm, inspired by his grandmother, who managed a multi-doctor veterinary clinic in his hometown. That is where his belief in veterinarian-owned practice began. He lives on a small farm in Somerset County with his wife, Dr. Elizabeth Pope, their sons Benjamin and William, their Labradors, Nora and Brody, and a small herd of cows, goats, and chickens. When he is not at one of the hospitals, you will find him fishing the Raritan or golfing.

Dr. Elizabeth Pope Co-owner · South Branch Veterinary Services Elizabeth grew up in New Jersey knowing she wanted to be a veterinarian. She met Nick at Oklahoma State's veterinary program, and the two returned to New Jersey to build something of their own. She has been part of South Branch Veterinary Services since 2017, with a focus on internal medicine, dentistry, and leading the South Branch team.
