About Us
Established in 2025, 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 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.
If excess adiposity often drives metabolic disease, its
converse, loss of muscle and bone, reduces resilience.
Progressive loss of musculoskeletal tissue and physiological
reserve represents a complementary and under-recognized driver
of declining health. Our secondary focus is thus on treating
conditions such as sarcopenia, osteoporosis, and frailty—each
associated with impaired mobility, falls and fractures, loss
of independence, and increased mortality.
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 Hamilton 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. He continues to do research through the
Geras Centre for Aging Research., and serves as an Adjunct Assistant Clinical Professor in Medicine at McMaster University. His research has focused on the learning and execution of
complex behaviours, and changes in body composition with
aging.

Referral Process
- Refer a patient using our referral form or Ocean eReferral. eConsult requests are also accepted via OTNHub.
- Mark any "urgent" referrals requiring evaluation within 2 weeks as such, as well as those patients who prefer to be seen only by video conference.
- Contact the clinic if your patients need evaluation and management of related comorbidities not listed above.
- Referral criteria will be adjusted over time, to encompass a greater range of delayable or preventable age-related disease.
- Wait times are currently < 2 months (as of ).
