Meet The Team

Our compassionate and dedicated veterinary care team!

Just like Cheers, where everyone knows your name, we’re proud to be Niagara’s first specialty referral animal hospital, creating a lasting legacy in our community with our compassionate and dedicated veterinary care team.

Meet The Owner- Dr. Kirsten Ness

Dr. Ness is a veterinarian, visionary, humanitarian, and constant student of life. She graduated in 1991 from the Ontario Veterinary College at the University of Guelph in the honours program. The plan was always to practice large animal medicine. However, after graduation, Dr. Ness started working at a small animal clinic in the Kingston area and has never looked back!

Upon moving to St. Catharines in 1993, Dr. Ness practiced at local small animal clinics, and at a local emergency clinic, before purchasing Glenridge Animal Hospital (GAH) in 2010. Since owning GAH, Dr. Ness has acted as a referral surgeon for other clinics, as her passion lies in the surgery room. She also regularly takes continuing education classes to keep up to date with all the changes in the veterinary field. When she is not at the clinic, she is either curled up with her kitties or traveling the globe, as her second passion is traveling.

Dr. Ness’s philanthropy work includes funding students in the 1-year wildlife protection college program in Tanzania as well as a future goal of building a safari camp in Serengeti. When Dr. Ness travels to Africa, she’s reminded of the big picture that everyone and everything matters from the insects, to the rodents, to the large animals. She believes that if we can save the wildlife, we can save the planet.
