Dr. Sandi Rosely

Ontario Veterinary College 1996

I can’t believe it has been 20 years since I graduated from the Ontario Veterinary College in 1996.  The past 15 years since the opening of Avonlea and 8 years since the conception of Hollybank have been very busy. I can definitely say that “time flies when you are having fun” or more specifically in my case “doing what I love doing”, which is providing veterinary care to your four legged companions and helping to educate you about how to care for your friend. My inspiration to become a veterinarian began when I was 8 years old. Through much dedication and devotion, I was able to save two wild baby birds and release them back to nature. I continue to feel the same happiness and sense of accomplishment that I felt when those birds flew away, when I help you help your furred friends.
DrSandiRoselyPetsWhen I am not at the clinic you may find me at the hockey rink cheering on my two boys, Bradley and Russell. Donnie, my husband, keeps a low profile mostly staying in the back fixing the computers and completing any odd jobs that are required. We are home to many four legged furred family members who keep us on our toes. After the passing of our beloved Hector, Dunkun, aka “Dennis the Menace”, came into our lives. He is a very active and intelligent Border Terrier who has definitely learned how to get what he wants,  including his sister, Alena.  Alena is a beautiful and sweet (no bias here) Rottweiler who loves her family and chasing her ball.  Celine and Zuuk our two cats provide entertainment for Dunkun and Alena and prove that “dogs drool and cats rule”.  Life is certainly a whirlwind, but I wouldn’t change a thing!

Temporary Closure of Hollybank and Modified Hours at Avonlea


To Our Valued Clients,

Our top priority is to provide exceptional care to our patients while safeguarding our staff and our community. At this time, we are temporarily closing our Milton location, Hollybank Animal Hospital, and we will be modifying our business hours at our Mississauga location, Avonlea Animal Hospital, where we remain available to see you and your pets for essential veterinary health care services.

This is a precautionary measure and there has been NO KNOWN COVID-19 EXPOSURE. Dr. Rosely has developed a mild fever and we have elected to have the staff which recently worked closely with her to also self-isolate for 14 days as a preventative measure.

Hollybank Animal Hospital will be closed effective this evening, March 31, 2020 at 7:00pm for 14 days. We will reopen April 15th, 2020 at 8:00am. We apologize for any inconvenience this may cause.

Our Mississauga location, Avonlea Animal Hospital, will remain open during this period to continue to service our clients and patients. Our staff will be contacting you to reschedule any appointments or procedures that were scheduled during this period.

Our hours of operation at Avonlea Animal Hospital for the next 14 days will be as follows:

·       Monday: 9a-5p

·       Tuesday: 10a-6p

·       Wednesday: 9a-5p

·       Thursday: 10a-6p

·       Friday: 9a-5p

·       Saturday and Sunday: closed

We trust that you will understand our cautious approach to this matter and we thank you in advance for your cooperation.
