Dr. Donna DiGregorio

Dr. DiGregorio has joined our team while Dr. Kahn is away on maternity leave.  She started her career here with us many years ago as a veterinary assistant. She then went on to attend the Veterinary College at the University of Edinburgh, Scotland. After graduating, Dr. DiGregorio worked for three years practicing small animal medicine in Collingwood. We are thrilled to have her back on the team!  She shares her home with her partner and sweet black cat named Slim.

To our valued clients,

Our hospital is currently operating with limited staff. There are no doctors available this week, but we continue to be available for food and prescription pick-up.

Due to this, we have temporarily reduced our hours of operation until further notice. We are also experiencing an influx of emails and calls and are doing our best to get back to you as soon as possible. We apologize in advance for any inconvenience this may cause.


  • Mon, Tues, Thurs, Fri: 8:00 am - 7:00 pm
  • Wednesday: 8:00 am - 8:00 pm
  • Saturdays: 8:30 am - 2:00 pm
  • We ask that you continue to be kind to all of our team members. Please know that we are working tirelessly to return to regular programming for you and your cherished pets.
