Live healthier, longer.
The average American lifespan (number of years you live) is 76.4 years. While the average healthspan (number of healthy years) is just 63.9 years. Our mission is to shrink that gap by adding years to your life and life to your years.

Dr. Jesse Greer
Drawing on his experience as a Special Forces physician at Walter Reed National Military Medical Center and on the front lines in Afghanistan, Dr. Greer founded Preamble to offer proactive, personalized health management to people committed to improving their lifespan and healthspan.
The Preamble Program
Instead of waiting to treat diseases after they arise, we focus on proactively preventing illness by providing a clear, personalized roadmap to your health based on deep diagnostics, expert interpretation, and long-term coaching support. In turn, we help you live your best life from the day you walk in.

The Book oN Preventative Health
We recommend the bestselling book, Outlive, by renowned physician Dr. Peter Attia, which clearly explains the principles of preventative healthcare — also known as Medicine 3.0. This modern approach focuses on preventing disease before it starts, using personalized, data-driven strategies to improve both lifespan and healthspan. When you’re ready to begin your own journey, Preamble is here to guide you.
