About
Chris Renna, DO founded LifeSpan Medicine in 1992 after recognizing that medical training prepared physicians to manage disease but left little framework for building health. That insight drove him to develop an entirely new clinical system, one organized around optimal function rather than symptom management. He earned his undergraduate degree from the University of Texas, then his medical degree cum laude from the University of North Texas Health Science Center, and completed a residency in Family Medicine.
Dr. Renna holds clinical expertise spanning regenerative medicine, hormone health, integrative nutrition, sleep, anti-aging, and high performance medicine. He personally leads the Platinum Program, the practice's most intensive annual longevity offering. A published author and frequent public speaker, he has lectured to audiences across the United States and internationally. His clientele includes Olympic athletes, NBA and NFL players, team owners, celebrities, and executives, many of whom travel from abroad specifically to work with him.
