Dr. Kerry Graybiel is the Division Head of Vascular Surgery at Humber River Hospital and a prominent vascular surgeon in Ontario. He received his medical degree from the Michael G. DeGroote School of Medicine and completed fellowship training in Vascular Surgery at McMaster University. He holds an academic appointment with the University of Toronto's Division of Vascular Surgery, where he contributes to the training of the next generation of surgeons.

His clinical practice spans the full spectrum of vascular disease, with a particular focus on chronic venous insufficiency, lower extremity venous disorders, and wound care. He is proficient in the advanced endovenous and endovascular techniques that define modern vascular surgery, and grounds his work in evidence-based preventative and therapeutic care.

As Chief Medical Officer, Dr. Graybiel sets the clinical standard for Own Health's pathways and leads the development of our Long-Term Care programs — extending specialist oversight into settings where complex, frail patients have historically had the least access to it. His combination of surgical depth and systems thinking is central to how we keep care safe as it scales.
