About

Meet Dr. Rehan Umar: Endocrinology & Internal Medicine Specialist

I am pleased to be part of the Doctors On Site team as a Specialist in Endocrinology, Diabetes, Internal Medicine, and Weight Management. I am currently seeing patients through our virtual platform and am accepting referrals for comprehensive endocrinology and obesity medicine care.

All of our OHIP-covered programs involve both physicians and a supporting care team, including allied health professionals, to provide comprehensive, patient-centered care. My goal is to deliver evidence-based, timely, and practical specialty care while maintaining clear communication with referring providers.
