Meet Our Team

Dr. Ariana Spina

Dr. Ariana Spina has been a part of the Greenboro team since 2018. 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 dentistry. 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 is also an avid reader and enjoys travel, playing hockey, cooking new pinterest recipes, and going to her family cottage in the summer months.

Dr. Justine Antunes

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.

Rachel Bourgon

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 painting, gardening, preparing for Halloween and riding her motorcycles, SeaDoos or snowmobiles with her husband nearly as much as spending quality time with her Havanese pups Hazel and Zeke and her birds Trooper and George.

When not saving pet lives, Miranda enjoys going for hikes and outdoor adventures, playing Pokemon, and watching movies. Miranda is very passionate about mental health, and always ensures she has time for her favourite self-care activities, sometimes joined by her exuberant cat Garchomp.

Cassidy Spero

Cassidy grew up in a small town outside of Ottawa where she was always surrounded by animals with her many pets at home. Her passion has always been about animals and animal health, which is why she chose a path within Veterinary Medicine. She is a graduate of the Algonquin College's Veterinary Assistant Program and came to work with us after completing her course in 2016.

Her favorite thing about Veterinary Medicine is being able to make the pets & pet parents experiences at the office as friendly and fun as possible. She can be found at the reception desk talking our clients through their visits, and handing out treats to our four-legged patients!

Outside of work, Cassidy is always having adventures with her husband Derek and her step-daughter. They love to be traveling, camping, or even enjoying a relaxing day at home watching documentaries. The 3 of them live with their two energetic cats, Monster and Boomer, and their sweet guinea-pig Sunny.

Katie Jones

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!

Mandy Dombroski

Mandy Dombroski has been a valued member of the GVC team for the past 14 years. Most of you know her as the warm welcoming face at reception that your pets go to for treats.

Mandy attended Algonquin College’s veterinary assistant program, 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 been with us ever since!

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

Daniella Briones has always grown up with animals by her side. Her love for creatures is what inspired her to start a journey towards veterinary medicine. Recently she has applied to both Queens and McGill university for an undergraduate degree in General Science. Her future goal is to attend Guelph University to obtain a DVM degree.

Daniella has always had an interest in animal medicine, having lived with her veterinarian grandpa (Dr. Roberto Briones) and accompanying him to work most days. She lives with two crazy wheaten terrier/poodle mix named Jaxon and Tesla.

In the future, Daniella Hopes to be just as talented as the many Doctors here at GVC.
