What the data says
Healthspan is what really matters
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.
The Founder
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.
How it works
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.
Step 1: Executive Physical
A comprehensive, multi-hour diagnostic that goes far beyond a standard annual checkup — measuring everything from cardiovascular risk to metabolic performance.
Step 2: Health Intelligence Report
Your results turned into a clear, personalized report with biomarker tracking, trend analysis, and a prioritized view of your health risks and opportunities.
Step 3: Personalized Action Plan
Evidence-based recommendations for nutrition, exercise, supplementation, and monitoring — co-created with your physician and adjusted as your data evolves
Step 4: Execution and Support
Take the next steps your data calls for in the areas of movement, nutrition, and supplements (if needed) and we'll support you every step of the way.
Step 5: Repeat
Your data will change over time. Our memberships include additional visits and testing that will sharpen your plan and make your next moves even smarter.
