About Us

MapleTree was founded by Dr. Christopher Greenwood, a residency-trained internal medicine specialist. As an internist, Dr. Greenwood is passionate about minimally invasive diagnostics and providing empathetic care to people and animals. In fact, Dr. Greenwood was voted by his graduating Ontario Veterinary College classmates as the vet they would choose for their own pets. He considers this his highest honour.

Dr. Size joined our team in 2023 after practicing in Eastern/Central Ontario. Dr. Size has worked in both regular and emergency practices and enjoys the diversity of veterinary medicine. She has always had a special interest in ultrasound. Inspired by her mentor at a young age, she also worked in diagnostic imaging while studying at the Ontario Veterinary College. She continues to take training courses to further develop and add to her skills.
