Holistic Nutritionist - Integrative Medicine​/Longevity​/Complex Illness

Vivagen Life Sciences is a leading functional medicine and longevity clinic dedicated to delivering comprehensive, integrative, and personalized healthcare. Our mission is to empower patients to achieve optimal health and well‑being through prevention, innovation, and advanced medical solutions. We stay ahead of the curve with cutting‑edge diagnostics and therapies that help clients turn back the clock on aging and live longer, healthier lives.

We are currently seeking an experienced Holistic Nutritionist to join our growing multidisciplinary care team at our Yorkville clinic. This is an in‑clinic role, 2–3 days per week, working closely with a visionary team—including direct collaboration with Dr. Tim Cook, Vivagen’s Founder and Medical Director. Dr. Cook is an award‑winning Internal Medicine Specialist and pioneer in longevity and integrative health, known for tackling complex medical cases and advancing health optimization across Canada.

This is not the typical nutritionist role built around generic meal plans or surface‑level dietary advice. At Vivagen, nutrition is a clinical pillar—deeply integrated with personalized genomics and diagnostics, chronic illness treatment, and longevity medicine. You will work with patients who are seeking a higher level of care, often with complex health histories, and who are motivated to make meaningful, lasting change.

As a Nutritionist at Vivagen Life Sciences, you will deliver high‑quality, client‑centered consultations within a setting that blends specialized care for complex chronic illness with advanced longevity and preventive health strategies. You will conduct comprehensive assessments, develop personalized nutrition protocols, and collaborate closely with our medical team to support patients through transformative health journeys.
