Preamble Health is Arizona's leading longevity clinic, located in North Scottsdale and built around a single purpose: preventing the preventable. Founded by Dr. Jesse Greer — a former Green Beret, Special Forces Flight Surgeon, and Internal Medicine physician — the clinic operates on a mission-first philosophy that replaces reactive disease management with proactive, data-driven health optimization. Where most annual checkups deliver vague advice and limited follow-through, Preamble delivers advanced diagnostics, expert clinical interpretation, personalized wellness strategy, and sustained long-term coaching built around each patient's unique physiology and goals. All Preamble services and memberships are HSA/FSA eligible — making physician-level longevity care more accessible than most patients expect.

About the Practice

Dr. Jesse Greer founded Preamble after experiencing the shortcomings of traditional healthcare firsthand — both as a physician and as someone who has operated in the most demanding physical and cognitive environments imaginable. As a former Army Green Beret and Special Forces Flight Surgeon with additional training in Internal Medicine, Dr. Greer brings a mission-first mindset to longevity medicine: clear objectives, systematic assessment, and a commitment to building resilient, high-performing individuals who can operate at their best for decades. After years treating acute illness and trauma, he built Preamble to shift the equation upstream — intervening before disease takes hold, not after. The clinic is recognized as one of Arizona's top longevity practices and focuses on five interconnected areas of health: Risk Mitigation, Movement, Nutrition, Sleep and Lifestyle, and Quality of Life. Every patient's program is a blueprint, not a checklist.
