Dr. Jason Ellis

    I decided to become a veterinarian because I enjoyed working with animals and was looking for a rewarding career where I could help both people and animals while at the same time challenging myself. I attended the Ontario Veterinary College at the University of Guelph and graduated in 2001. I have been practicing veterinary medicine at the Whites Road Animal Hospital and Highway 2 Veterinary Office since I graduated.

    The best aspect of being a veterinarian is knowing that I am helping animals to live a healthier and happier life in addition to helping the people who care so much about them.  It is very satisfying to know that I am making a difference in the lives of both people and their beloved pets.

     I take great pride in knowing that my clients trust me. I value the opportunity to listen to their concerns and address these concerns in an honest and straightforward manner. I believe that clients can appreciate that I want to work with them to provide the best care for both them and their pets by using my experience and knowledge and an understanding of what type of care they would like their pets to have.

    My lovely wife, Diane, was a classmate of mine and is also a veterinarian.  I have two wonderful daughters, Jillian and Violet, as well as two cantankerous cats, Annie and Cubby, and two adorable guinea pigs, Spooks and Buttercup.
