HealthSpan Chicago is a membership-based longevity medicine practice in Deerfield, Illinois, serving the Chicago North Shore area and greater Chicagoland. Founded by Dr. Tyler J. Saunders, DO, the practice operates on a direct primary care model with an intentionally small patient panel — built around the premise that meaningful longevity medicine requires time, continuity, and a physician who actually knows your full picture. The focus is entirely proactive: advanced diagnostics, lifestyle intervention, and a personalized 30-year health roadmap — not reactive symptom management.

About the Physician

Dr. Saunders is a board-certified Internal Medicine physician, former Chief Resident, and former core faculty member of the Internal Medicine Residency Program at Swedish Hospital — Endeavor Health in Chicago. He earned his medical degree from Lake Erie College of Osteopathic Medicine and conducted pancreatic cancer research at the Johns Hopkins Sol Goldman Pancreatic Cancer Research Center before medical school. He is also a certified practitioner through the Institute for Functional Medicine. Dr. Saunders has been featured in CBS Chicago, WGN Chicago, Food and Wine Magazine, Veranda Magazine, and Peloton’s The Output, and regularly speaks on longevity and lifestyle medicine throughout the Chicago area.
