Our Veterinarians

Dr. Ariana Spina

Veterinarian, DVM

Dr. Ariana Spina is ecstatic to be part of the GVC Teem! Ariana was born and raised in the countryside of Thunder Bay, Ontario. She spent her summers at her family cottage, teaching the men in her family how to fish. In the winters, Ariana played hockey and enjoyed snowshoeing in her back yard.

Ariana graduated with first class standing from Lakehead University in 2014, where she received a Bachelor of Science Biology degree. During her undergraduate degree she worked at her local humane society as an animal care attendant. She also worked at a local mixed-animal practice, where she found her love for small animal medicine; this was where she decided that large animal medicine, especially in the middle of harsh northern Ontario winters, was not for her. Ariana then continued her education at the Ontario Veterinary College, where she received her Doctor of Veterinary Medicine degree and graduated with honours in 2018.

Ariana has many passions in veterinary medicine, but has a keen interest in preventative medicine, nutrition, and behaviour. She believes in working as a team with her clients to ensure the best possible care for their pets. Ariana strives to make every experience at the vet the most positive it can be, and has earned the nickname “Dr. Cheez” as she uses Cheez Whiz to make routine appointments more enjoyable for her patients.

Outside of veterinary medicine, Ariana enjoys walking and hiking with her Jack Russell Terrier, Pippa. She also enjoys travel, playing hockey, cooking new pinterest recipes, and going to her family cottage in the summer months.

Dr. Justine Antunes

Veterinarian, DVM

Dr. Justine Antunes grew up in the small town of Courtice, Ontario, just east of Toronto. As a child, she spent a lot of time pouring over dog breed encyclopedias, watching animal planet, riding horses, and playing soccer. She attended the University of Guelph where she received her Bachelor of Science degree with Honours in Biomedical Science in 2014. She then started her studies across the road at the Ontario Veterinary College, and graduated with honours in 2018.

Dr. Antunes's main interests as a veterinarian include behaviour, surgery, neurology, and preventative medicine. During her veterinary studies, Justine worked in the Ontario Veterinary College Companion Animal Behaviour and Welfare Lab, where she worked with both dogs and cats. This founded her strong interest in behaviour, and provided her with the opportunities to present her research at conferences in North America, as well as work with veterinary behaviourists in the United States. Dr. Antunes has a keen interest in working with dogs with behaviour problems in order to improve their bonds with their owners, and hopes to ensure that each veterinary visit is a positive and fear free experience for dogs and cats.

When not in the clinic, Justine is an avid soccer fan. Growing up in a Portuguese family meant soccer was a necessity, and she both watches and plays. She's a strong supporter of Liverpool F.C., and was absolutely ecstatic when they finally brought home another trophy after winning the Champions League in June 2019.

Justine has an adventure buddy named Ellie, who is a Golden Retriever, and they enjoy spending their time off exploring new trails, beaches, parks, and anything to get Ellie's zooms out.

Dr. Derek Fingler

Veterinarian, DVM

Although Dr. Derek Fingler always loved animals and grew up with Ginny, his family’s lovable retriever mix, by his side, he didn’t always know that veterinary medicine was his calling. After high school, Derek ventured into engineering, attending Royal Military College where he received a Bachelor of Mechanical Engineering degree and started a career as a Naval Marine Systems Engineering Officer.

Dr. Fingler says the next five years were some of the most rewarding and successful of his life, but he came to realize that he wanted to make an immediate difference in people’s lives and that he missed the animal bond he had felt as a kid. Veterinary medicine was his answer! He attended veterinary school shortly thereafter and never looked back. He’s been a professional veterinarian since 2000 and the original practice owner of Greenboro Veterinary Clinic since its opening in 2003 until early 2021.

Dr. Fingler has a special interest in dentistry—he says it plays nicely into his engineering-trained thinking process! His previous ownership role afforded him the opportunities and challenges of leadership and his current role as a mentor allows him the opportunity to share his years of experience.

Derek shares his life with his wife Anne and four young adult children. The family home is currently shared with daughter Alexe's dog Hadlee and a very entertaining cat named Todd (who thinks he is a dog).

When he has a spare moment, Dr. Fingler likes to ride his motorcycle, travel and escape to his cottage where he enjoys swimming, kayaking, tinkering on various items and playing board and card games.

Our Careteam

Rachel Bourgon

Practice Manager, RVT

Rachel Bourgon has felt a strong connection with animals since she was a young girl and knew she wanted to care for both people and animals. She never gave up on her dreams–since graduating from St. Lawrence College in 1998, Rachel has had a career of more than 20 years as a registered Veterinary Technician working in the field of small animal medicine!

Rachel loves every aspect of her job and tries to treat each and every pet as if they were her own. She enjoys caring for a pet’s emotional needs just as much as their medical needs while demonstrating an equal passion for excellent client care.

When she's not at work, Rachel enjoys gardening, riding her motorcycle or snowmobile with her husband nearly as much as spending quality time with her cat Beaner, her dogs Scooter and her birds Mama (the Budgie and real boss of GVC no matter what Pawl thinks) and Trooper (the cockatiel).

Keri Nelson

Registered Veterinary Technician, RVT

Keri graduated from Algonquin College’s Vet Tech program after doing her field placement with the Greenboro Veterinary Clinic. She was hired as a technician assistant/technician in training and has successfully become a registered veterinary technician and is actively developing her skill sets. She happily shares her home with two dogs, Charlie and Shadow.

Mandy Dombroski

Client Care Representative / Veterinary Assistant

Mandy Dombroski grew up in the small country town of Barry’s Bay looking after her many pets. After high school, she considered going to school for culinary arts, hotel management, or interior decorating, but her passion for animals won out and she decided to pursue her dreams in the veterinary medicine field!

Mandy attended Algonquin College to study veterinary medicine, during which she was positioned at Greenboro Veterinary Clinic for the field placement portion of her studies. She ended up staying after graduation and has worked as a Veterinary Assistant ever since! To this day, she is fascinated by the way a veterinarian can figure out the problem and proper treatment for an animal without them being able to speak. She loves being able to improve her skills, increase her knowledge, and give lots of hugs to clients’ furry companions!

Mandy lives with her cats Peanut and Squishy and an energetic terrier mix named Charlie. In her spare time, she likes to curl up with a good book, go hiking, watch documentaries, and spend all the time she can with her family and friends.

Cassidy Spero

Client Care Representative / Veterinary Assistant

Cassidy is a graduate of the Algonquin College’s Veterinary Assistant Program and came to work with us after completing her course. She is always excited and interested in every animal that comes to our care and has been passionate about animal health since she was little. Her favorite thing about Veterinary Medicine is being able to make the pet’s experiences friendly and fun, and putting a smile on our client’s faces.
When she has spare time Cassidy loves to be baking, camping or curled up on the couch watching television with her husband Derek and his daughter. The 3 of them live with their cat, Monster or Moe-Moe for short!

Katie Jones

Client Care Representative / Veterinary Assistant

Born and raised in Ottawa South, Katie has always had a passion for helping others. Although initially planning on becoming a police officer, Katie decided to take a different career path and obtained her degree in psychology in 2008. It wasn't long before her passion for animals had her going back to school for her veterinary assistant certification in 2014.

Although she loves all creatures, she has a soft spot for our feline friends. She enjoys working with grumpy kitties and winning over their trust by the end of the appointment. She has two black and white "tuxedo" cats at home named Eddie and Meeko (or as she calls them SpagEddie and Meekballs).

When not in clinic, she enjoys baking, biking, camping and gardening. She is excited to join the GVC family and is really looking forward to meeting our amazing four-legged clients!
