Dr Dawn Mussallem is a globally recognized physician-leader in lifestyle, integrative, and longevity medicine. She serves as Chief Medical Officer of Fountain Life – named Longevity Clinic of the Year 2025 – and as a Founding Scientific Advisor to IM8 Health, shaping evidence-based protocols and product strategy at the intersection of prevention and performance.

Over 20 years as a Mayo Clinic physician, she founded the Mayo Clinic Integrative Breast Oncology Program, integrating lifestyle medicine, integrative symptom management, mind-body therapies and precision nutrition into cancer care. Her journey is unlike any other.
