Book Marc

What if the greatest act of service begins with healing ourselves?

When people regain time, energy, and meaning, families, companies, and communities change. Marc shows audiences how the Longevity Trifecta  (biohacking, longevity medicine, and fulfillment) treats the source, not just the symptoms.

Fulfillment isn’t a feeling. It’s a
way of living.

About Marc

Marc Kielburger is one of the world’s most recognized voices on human longevity, fulfillment, and purposeful leadership. A New York Times bestselling author, member of the Order of Canada, and recipient of 10 honorary doctorates, Marc has spent more than three decades helping people add not only years to their lives, but life to their years.

He is the Co-Founder of Unlimited Life, a year-long longevity and transformation program built with Dave Asprey and Dr. Tim Cook, and the Co-Founder of the Dalai Lama Center for Peace and Education, which has helped millions of young people strengthen compassion, emotional intelligence, and resilience. Marc also co-leads Legacy+, a global collective that builds purpose-driven movements with world leaders, changemakers, and leading brands.

As Chancellor of Legacy College in Kenya, Marc helps guide one of the country’s top accredited institutions for nursing, business, and social entrepreneurship. His work in East Africa also includes the founding of Baraka Hospital, which now provides life-changing healthcare to thousands of families who previously had no access to medical support.

A graduate of Harvard University and a Rhodes Scholar at Oxford, Marc has collaborated with many of the world’s most influential thinkers and innovators, including Oprah Winfrey, His Holiness the Dalai Lama, Richard Branson, Melinda French Gates, Simon Sinek, and Martin Luther King III, to build initiatives that advance human potential, deepen compassion, and ignite social change.

Across every chapter of his work in education, healthcare, movement-building, writing, and teaching, Marc’s mission remains the same: to help people live longer, stronger, and more fulfilled lives, and to build communities and systems where human potential can truly thrive.

Marc is also an internationally sought-after speaker who has addressed more than 1.5 million people across major venues and global events, including Harvard, Oxford, the United Nations, the World Economic Forum, and stadium gatherings broadcast on ABC, CBS, CTV, Hulu, and iHeartMedia. His keynotes explore the Longevity Trifecta, a science-backed integration of longevity medicine, biohacking, and fulfillment, and how reconnecting to self, others, and purpose transforms health, performance, and impact.
