Dr. Krista Kean


Krista graduated from the Ontario Veterinary College in 2006 after fulfilling a childhood dream of becoming a veterinarian. After graduating she joined a small animal practice in King City, Ontario where she was thrilled to put into practice everything that she had learned while in veterinary school. After meeting her husband five years later, Krista moved to Burlington, Ontario where she worked at several local veterinary clinics and started a family. She now lives with her husband and two beautiful children in Richmond Hill, Ontario and is excited to have joined the warm and caring team at Kleinburg Veterinary Hospital.

Krista enjoys all aspects of veterinary practice including surgery, internal medicine, cardiology and especially caring for elderly pets and their unique needs.

When she’s not at work, Krista loves to spend time with her family and pets, including a hedgehog named “Emily”. She also has a passion for the fiber arts and enjoys macramé, knitting and crochet.
