Rebecca Ritchie, BSc, DVM

If you had asked me at 10 years old what I wanted to be when I grew up, I would have told you that I wanted to be an engineer. Thankfully, I have changed since then, and life brought me other opportunities. It began with science, but it was living among different creatures at University that really captured my interest. After working with maple trees, gypsy moths and caribou, I found myself applying to vet school. I had considered returning to work with wildlife, but I was captivated by small animal medicine and surgery—so here I am!

Rob Hillerby, BSc, DVM

My very earliest memory is a Saturday morning at my parent’s house when I was three years old. Their Irish Setter, Emma, had whelped 13 puppies a few weeks earlier and my dad had built a room in the basement for her to raise them in. I got up early that morning and went down the stairs and over the board in the doorway that kept the puppies in. Emma was happy to share her new family with her people, and welcomed me into the room. I remember the curious little balls of fluff crawling all over me and licking at my face as I laughed like a fool. I learned early on how good it felt to make a true connection with an animal and that has stuck with me. As soon as I realized that there was a job where I could help people to foster that connection with their own animals, I knew that was what I wanted to do. Every day I get to help animals live happier lives and I get to see how that affects the people who love them. I think that is a pretty good way to spend my time! I graduated from the Ontario Veterinary College in 2009, and I have a special interest in ultrasound imaging and dentistry.

Carol Hung, BSc, DVM

As a young child, I grew up with 8 cats living next door. I loved being in their company, and would spend all of my evenings playing outside with them. Eventually, I combined my love of cats (and all other members of the animal kingdom), science and helping people into my dream job as a veterinarian. Despite the fact that I am allergic to cats and dogs (you might hear my sneezes through the walls of CMVH), I love meeting devoted pet owners and their furry companions!

I obtained my Doctor of Veterinary Medicine degree from the Ontario Veterinary College in 2015. I have cultivated strong interests in dermatology, dentistry, and internal medicine. Outside of work, I enjoy hiking, scuba diving, and traveling.

Sherry Ekstrom, BSc, DVM

I graduated from the Ontario Veterinary College in 2010, and have been interested in caring for pets since I was very young. When I was three years old, I would take our neighborhood cat out for walks. His name was Toby, and he was a big orange tabby with a grumpy-looking face. My mom was allergic to cats—a fact that I tested out on multiple occasions when a stray cat would “accidentally” follow me into the house, and my mom would be sneezing for days. Toby was the closest thing I had to my own cat at that time. At every opportunity, I would knock on my neighbour’s door to see if Toby could come out and play, and his owners would dutifully hand him over to me. I would place him in my pink toy shopping cart and happily walk up and down the sidewalk, giving him a tour of the neighbourhood. In hindsight, he was an exceptionally patient kitty to deal with an overly affectionate three-year old so well.

Our routine continued for some time until the fateful day when Toby was chased up a tree by my family’s dog. Toby was fine, but he was no longer allowed to come out and play with me, and I was sad to lose my furry pal. It was around this time I decided that I wanted to become a veterinarian, so that I could help teach dogs and cats to be friends.

Over the years, my reasons for wanting to pursue this career have evolved, but I often think back to one of my first experiences with the human-animal bond as the start of my journey.
