Barbara Bacon

Hospital Administrator

Barb is an avid traveller, runner and cyclist and has competed in over 100 half-marathons (we're not sure why). She is our "Jill" of All Trades when it comes to running the clinic. You want something done, just ask Barb! Barb is involved with kitten fostering and often brings her kittens to visit at the clinic. After all, she practically lives there!

Barbara Bacon

Jr Hospital Administrator

Lisa's background is in medical laboratory, but she has left human medicine and gone over to the DOG side!  You can find Lisa's smiling face behind our front desk, in the back with the animals or working with Barb. Lisa is training to let Barb retire in the distance future. 

​When Lisa is not answering phones or generally organizing the clinic, she is spending her time working on an MBA in HRM or spending time with Pat, their dog, Harley Quinn and cat Monster :) 

Tracy Gaskell

Registered Veterinary Technician

Tracy is our lead RVT, so basically runs the place! She keeps everything organized, assists our surgeons, and makes sure our patients are comfortable. Fun fact... Tracy was a Covid bride! Her bridal party all wore masks to match their outfits! (pic above with team member Tanya C.)

Jenna Stewart

Veterinary Assistant

Jenna is an animal lover, a kid lover, and a cowgirl! She lives on a working horse ranch with her husband and 2 young boys. She loves working with us because it's easier than working on the ranch. Jenna makes sure our patients have a smooth recovery.

Caitlyn Eld

Caitlyn knew from the start what she wanted to be when she grew up, even though she has allergies to pets, did't stop her from having pets or going for her dream job. 

She successfully has a high school co-op at a vet clinic, loved it so much, no leap year for her, off to college ASAP to achieve her VA. 

Maddie S. 

VA

Hi! I'm Madi, and I aspire to be a vet tech. I've always loved animals, and I want to be a voice for those who can't speak for themselves. This line of work has always been my passion, and I am very grateful I found what I loved at such a young age.

Renee Parent

CCR

If you've ever called the clinic, you've spoken to Renee! Renee moved all the way from Edmonton to come and work with us. She was up for a new adventure and she loves to travel, so a brand new clinic was right up her alley. Fun fact...Renee has hiked the El Camino Trail...twice!

Emily Astleford

VA, CCR

Emily graduated from the Veterinary Assistant program in 2016 and has been in the field ever since, ranging from general practice, hospice care, to now a spay and neuter clinic. Emily is a part of our front desk team, but can often be seen having full conversations with the patients. When she is not at work, Emily can be found chasing after her twin toddlers, or hanging out with her mini-zoo at home, including dogs, a cat, fish, and a bearded dragon!

Tanya Crozier

VA, CCR

Tanya is an animal lover at heart. She enjoys her days with her energetic but cuddly Aussie, her two kids and husband plus their 2 cats, hamster and guinea pig GG. The kiddos may be following in their mom's footsteps. If you have had your pet at our clinic you may have chatted with Tanya on the phone or seen her in the round about at discharge time.

Kristen Coligan

VA, CCR

Kristen may fool you as the quiet one who calmly gets the job done, but she's no slouch when it comes to handling big dogs! Kristen is a big part of why our clinic runs so smoothly, and why all of our patients are so well behaved!

Carol Link

CCR

Married with 5 children and 10 grandchildren, I began my animal care journey at 18 with the Cape Breton SPCA in Nova Scotia, working in Animal Care, Control, and Welfare. After moving to Hamilton, I worked at the Hamilton SPCA and, later, in Ontario as a Cruelty Agent and Animal Care Attendant at the Brockville SPCA. I also worked as a CCR at the St. Lawrence Valley Animal Hospital before becoming a Manager at the SDG SPCA. With 27 years in the SPCA, I retired in October 2024. I now enjoy travelling, reading, and spending time with my 4 cats, 2 dogs, and grandchildren.

Pat Smith

VA, CCR, Maintenance 

Pat is our all-around IT guy, handyman, recovery room support, and token male!  If it's broken, we call Pat! If we need a problem solved, he's our guy! 

Pat loves working with animals, and he has a special affinity for cats and nail polish (we're not sure why).  When he's not in the office, or outside admitting and discharging or repairing something, he likes to spend time with his wife Lisa, their dog Harley Quinn and crazy cat Monster!
