Gillian Gwartz, DVM

Associate Veterinarian

Dr. Gillian Gwartz earned her Doctorate of Veterinary Medicine from the Atlantic Veterinary College on Prince Edward Island, prior to that she attended Colorado State University for her under graduate degree, which is where she fell in love with the state of Colorado.

Dr. Gwartz followed vet school with further training, completing a Rotating Small Animal Internship at Carolina Veterinary Specialist. There she worked with neurologist, internal medicine specialist, surgery specialist, cardiologist, ophthalmologist, exotic specialist, and spent time practicing Emergency medicine. After her internship she decided that she missed Colorado and came back to do general small animal practice.

Born in Uganda to Rwandese refugee Tutsi parents, I began life in a world of segregation, civil war, and abject poverty. Unable to return to the war-torn place of my origin at the time—and plagued by violent discrimination in my adopted country—I fought to find safe haven. As a child, the only constants were my grandfather, our cows and dogs. Because of Grandpa’s wisdom and our bond, I decided to pursue our love of animals as my profession. This is why I became a veterinarian.

For more on my story, please check out my book! Available on Amazon. I studied Veterinary medicine at Makerere University, Uganda; one of the best universities in Africa. I moved to America to advance my training with an internship in Kentucky and to give my family a better life. I took the American Veterinary Association required tests; ECFVG/AVMA (at Mississippi State University) to get licensed in the USA.

Now Dr Kalenzi owns two veterinary practices

"Rock Creek Veterinary Hospital" as well as its sister clinic "Niwot Veterinary Clinic" where he regularly practices at both locations.
