Meet our Doctors

Greg Matheson, DVM

Staff Veterinarian

General Surgery, Primary Care

Working at a local pet store was my first animal-related job back in high school. Before that, I found myself scared of dogs and allergic to just about every other bird and mammal you could imagine! Soon enough I discovered the human-animal bond and have since dedicated myself to protecting and preserving that connection between client and patient. I have had the pleasure of learning and working in New York, Massachusetts, Florida, Illinois, and finally Washington.
My driver’s license now reflects my roots in the District and our professional sports teams are seeing the benefit–you’re welcome! Outside of work, I keep myself busy teaching The Polite Puppy class, tabletop gaming, trail running, playing instruments, enjoying DC’s live music scene, and binge-watching shows with my cat, $quid!
