Dr. Simon Overduin Internal & Geriatric Medicine

Overduin Clinic

Cardiometabolic health and longevity medicine

About Us

Our mission is to be the first publicly-funded longevity clinic in Canada, helping motivated patients to maximize their healthspan and lifespan. Our initial focus is on metabolic dysfunction, the dominant driver of cardiovascular disease, which itself is the leading cause of death in North America and worldwide. We believe most metabolic dysfunction and downstream cardiovascular disease can be prevented or substantially delayed through risk stratification, early detection, and individualized interventions. Further, we believe that timely treatment of cardiometabolic conditions can reduce risk of other major morbidities including diabetes, cancer and dementia.

Dr. Overduin obtained his MD from McMaster University, followed by specialization in Internal Medicine and subspecialization in Geriatric Medicine. He completed additional post-fellowship training in metabolic and lipid disorders at the Wharton Medical Clinic for Weight Loss in Burlington and the Lipid Clinic at Hamilton General Hospital. He also completed a PhD in neuroscience at MIT, and worked as a postdoctoral fellow and research affiliate in computational neuroscience and neuroprosthetics at Boston University and the University of California Berkeley. His research has focused on the learning and execution of complex behaviours, and changes in body composition with aging.
