From Mobile Veterinary Care to Danbury Animal Hospital
Our Story
Dr. Jean Quaintance, Dr. Theresa Kaeser and Don Quaintance founded Versatile Vets in 2017 as a fully mobile veterinary practice serving pets throughout Connecticut. Their goal was to create a different kind of veterinary experience: one that felt approachable, relationship-driven, and centered around quality care rather than quotas or rushed appointments.
Over the years, they built strong relationships with families across Greater Danbury, many of whom still trust them with multiple generations of pets today.
In March 2020, Versatile Vets grew into Danbury Animal Hospital with the opening of the practice’s first hospital location. While the practice now has a permanent home in Bethel, mobile veterinary care remains an important part of what we do, with qualifying appointments available on Wednesdays and Thursdays.
Although we’ve grown over the years, the heart of our practice hasn’t changed. We continue to provide advanced veterinary care with the same warm, personal approach that has guided us from the very beginning.

Built Around Relationships.
