Dr Dawn Mussallem’s life has defied all odds. After surviving stage 4 cancer, severe heart failure, and a heart transplant, she ran a marathon just one year later. In this conversation, I sit down with Dawn as she shares what she’s learned about resilience, faith, and the science of healing.

We explore the mindset behind recovery, how food and lifestyle can prevent disease, and the lessons from decades of cancer research and clinical care. It’s a deeply human discussion on what it means to live with intention, vitality, and compassion.

What We Cover

A testament to the strength of the human spirit—and a guide to living better, not just longer.

Connect with Dr Dawn Mussallem on Instagram or LinkedIn to follow her work in lifestyle medicine, cancer recovery, and longevity research.
