    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.

    I grew up in Montreal, Quebec. Before I was accepted into the class of 1986 at the Ontario Veterinary College, I completed a Bachelor of Science with a major in Microbiology at the University of Guelph. My love for medicine, people, and caring for pets made veterinary medicine an easy career choice - I do not remember a time in my life when I did not want to be a veterinarian.

    I have been working with White’s Road and Highway 2 Veterinary Clinics since 1995. My main veterinary interests include meeting new and long-standing clients in the front office, where I enjoy helping them solve a range of concerns in a positive and compassionate manner. I practice with a core philosophy of kindness, sincerity, and client-centred care, with the goal of helping to keep pets happy and healthy.

    Away from work, I enjoy spending time with my family; twins, Erin and Scott, who are now 22, Ryan, who is 25, and my husband, Kim. My 4-legged family consists of Moe, a 7-year-old toy poodle and Bear, a 14 and ½-year-old domestic shorthair. I have a special love for Chesapeake Bay Retrievers, as they have been a huge part of my life for many years.

    Despite growing up with only turtles, I have wanted to become a veterinarian since I was in grade 1. I knew I have always wanted to work with animals, but as time passed, I became interested in the capability of medicine to help develop the human-animal bond. Although, the adorableness of animals also was an encouraging factor!  

    I graduated from the Ontario Veterinary College in 2016. These past years as a veterinarian have been incredibly rewarding. My favourite aspect is educating clients on their pets health and being able to utilitize my skills as a surgeon. Greeting our clinic cats every morning is also a highlight. 

    I have two turtles, a leopard gecko and two of the best cats, arguably, in the world. When I'm not at work, I enjoy being outdoors, playing volleyball, painting and spending time with my cats.
