Dr. Sarah Machell


Dr. Sarah graduated from the University of Guelph with a Bachelor of Science degree in 1993. She then continued at the University of Guelph, Ontario Veterinary College (OVC) and graduated in 1997. She later founded North Oakville Animal Hospital in 2000.

When Dr. Sarah was 4 years old, she told her mother that when she grew up, she wanted to be a veterinarian. Her close bond with her family cat, Marmalade, who lived to the ripe old age of 21, was her inspiration to choose a profession where she could help and care for animals. She started working in animal hospitals at the age of 15 and knew she had found her passion.

Dr. Sarah, her husband Terry, and their two sons Gibson and Korben enjoy the canine companionship of their Rat Terrier, Sony and loveable Golden Retriever, Cheddar. The family also has two crazy kitties, Herriot and Peachy, as well as so many goldfish that they have run out of names! Dr. Sarah maintains a close working relationship with Oakville and District Humane Society. In her downtown, she enjoys reading, playing ice hockey, and visiting the family's northern Ontario getaway spot.
