Meet the founder
Pillar Healthspan was founded by Corey Sadler, DO — a board-certified family physician — to practice medicine the way it should be practiced: unhurried, measured, and built around the years of healthy life ahead of every patient.
Dr. Sadler spent most of his career inside large medical systems — the U.S. Air Force, a federal medical group, and the Veterans Health Administration — managing primary-care panels of well over a thousand patients, from newborns to adults in their early hundreds. That work spanned the full range of primary care: chronic disease, preventive medicine, sports and musculoskeletal care, men's and women's health, and in-office procedures. It also exposed a structural flaw he built Pillar to correct — the system is designed to react to illness, not to protect health.
A different kind of training
Before medical school, Dr. Sadler earned a graduate degree in microeconomics, concentrated in data analytics and risk analysis — the discipline actuaries use to quantify how likely an outcome is, and when. It is an unusual foundation for a physician, and a deliberate one: it shapes how Pillar measures risk, quantifies physiologic reserve, and tells each patient plainly where they stand and where they are heading.
That thinking is the foundation of the Healthspan Reserve Index — Pillar's measure of physiologic reserve.
Practice, not theory
Dr. Sadler lives in Little Rock with his wife and son — a daily reminder of what the work is ultimately for: more good years with the people you love. The four pillars are not abstractions to him. He's an outdoorsman, a fly fisherman and bow hunter, and a committed student of nutrition and training.
"I don't ask my patients to do anything I don't do myself."
That conviction was shaped in demanding settings. He deployed to East Africa as a deputy surgeon supporting special operations forces, serving as lead physician for a small team in a remote environment where physical resilience genuinely mattered. The experience left him with a lasting respect for what the body can do when it's built to last — and the belief that those same principles belong in everyday medicine. It is the standard he holds Pillar to.
