Client Care Specialist

Sarah arrived in Ontario after leaving the corporate world of Calgary and is our Client Care Specialist and one of our veterinary assistants (in other words “Jack-of-all-Trades”).  She has worked here at Chedoke Animal Hospital for over 15 years and will likely be the first bright smile that will greet you as you come in to the clinic.

Growing up in the Yukon, most days were an adventure for her. She enjoyed many outdoor activities such as snowmobiling, dog sledding, white water rafting, camping and flying a helicopter with her Dad.  Her little town was beside Kluane National Park and on a clear day, Mount Logan could be seen out of her front window. The Northern outdoors exposed her to a wide variety of wildlife. If you ever want to hear some of her funny wildlife encounters, ask her next time you stop by. 

Now in her free time, Sarah enjoys pet sitting and spending time with her husband Arran and their fur family, which includes 2 cats; Emma and their big trouble maker Gary.

In her spare time, she can be found swimming, taking her dogs for walks or working on the agility field.
