Dr. Karen Macmillan-Wuebbolt

Associate Veterinarian

My best friend, Frisky, defended me against a rabid fox. At the tender age of five, something changed inside of me when I saw the OSPCA take my cat away with a rabies pole. A veterinarian was born. I graduated from the University of Guelph with an honours degree in Biomedical Science. In 2002, I graduated with my Doctor of Veterinary Medicine degree from the Ontario Veterinary College. ‘Neurologic complications following treatment of canine hypoadrenocorticism,’ was my first published journal article as a Veterinarian. I learned how to be a practitioner at clinics across Toronto. I made sure all my patients were vaccinated for rabies. My husband and I settled in the Beaches in 2010. During the renovation of our house, we were blessed with the birth of our son. Our family is complete with our fur babies including Vader our tuxedo cat, and Rousey the Bengal. I am excited to start a new adventure, meeting all of the adorable cats and dogs at Greenwood Park Animal Hospital.
