Paula Dupuy, DVM, CCRV

Dr. Paula grew up on a farm in Flamborough, near Valens. Her father, Harry was a “gentleman farmer”, living his dream after a long career in manufacturing in the energy industry. He populated the farm with cattle, sheep, chickens and most importantly, horses. Dogs and many cats were also a big part of the picture and Paula grew up surrounded by animals. After high school, Hillfield-Strathallan College, Paula decided to leave the farm and test out city life in Montreal where she attended McGill University. It wasn’t long before Paula greatly missed the country, riding horses and her home. She decided to apply to veterinary school and moved back to Ontario to attend the Ontario Veterinary College. There, a lifelong passion began. Paula graduated in 1992 and with a little wanderlust, moved to New York state where she worked in mixed practice for 11 years. Paula credits this time for really cutting her teeth in the business. There was a lot less support than there is now, and the case load was intense. Referral was rarely an option and Paula dove into the deep end of veterinary medicine, dealing with whatever was in front of her in the best way that she could.

Paula returned to Ontario in 2003 with her daughter Isabel and started Troy Veterinary Mobile. This quickly morphed into Troy Veterinary Services and now Troy Animal Hospital and Troy Equine Services. These practices were built one patient, one client at a time. Dr Paula’s goal has always been to provide personalized, compassionate care, seeking answers to all problems and offering a veterinary service that was both excellent and fair. She believes staying true to this practice model has been the key to our success. The veterinarians and support staff who have joined the team, committed to this same mission, have made this practice much greater than she could ever have done on her own.

Most recently, Paula has developed an interest in canine sports medicine and lameness, applying concepts that she developed in equine practice to canine athletes. Certified as a Canine Rehabilitation Veterinarian (CCRV), Paula enjoys solving lameness issues in dogs, using musculoskeletal ultrasound and thermal imaging.

In 2011, Paula lost her daughter Isabel in a car accident, while on call, due to black ice. This event was a turning point in her life. She says that it has made her only more compassionate and more determined to live every day to its fullest, being the best veterinarian and employer that she can be. Life is a journey and how we live it, is all that matters.

There are not enough hours in the day for Paula, who when not practicing veterinary medicine, can be found with her horses and her hunt club, with her husband Johnny on their boat, playing the piano or the flute, or knitting garments for friends.

Her most recent accomplishment has been building a veterinary practice in the historic Westover General Store. With a love of history and the community, Dr Paula calls this her legacy project. She has honoured the history of the building, while creating a professional space to care for your companion animals. Come and see her there!

Rayna Jancar, Registered Veterinary Technician

Rayna was born here in Cambridge Ontario, and moved around to live in London, Calgary, and Toronto before moving back to her roots in Cambridge. She was able to spend a lot of time on her grandparents farm where she was always surrounded by animals. (Also where she discovered they weren’t just fun for eating!) Rayna went on to complete an Equine Coaching program at Humber College and joint Troy in 2008. After working in an assistant role she decided to attend veterinary technician school at Sheridan College while still employed at Troy Veterinary Services. Rayna describes going back to school in her 40s to become a registered veterinary technician as one of her great professional accomplishments as it was a passion of hers for so long. Away from the clinic Rayna enjoys being very involved with her church and going for hikes with her husband and Cane Corso, Frankie.
