MEET DAVID
Dr. David Barzilai is a longevity physician, Harvard Medical School Lecturer, and the founder and CEO of Barzilai Longevity Consulting. His work spans two distinct practices: a selective private retainer practice for executives, entrepreneurs, and highly motivated individuals seeking an independent scientific partner alongside their existing care team, and scientific and strategic advisory engagements with longevity clinics, biotech and health-tech companies, and health-sector organizations. The connecting thread across all of it is the same: translating frontier longevity science into decisions that hold up to scrutiny and improve outcomes.

From David
I work closely with each client, one-on-one, to support their long-term wellbeing. I am a physician, but I am not your physician in this relationship. No diagnoses or treatment are rendered. Through my consulting practice, I work with clients to translate the science into the decisions that move them toward their personal and professional goals.
