In this episode with Jimmy St. Louis, you'll hear how a former NFL player, US Olympic rowing trials competitor, and four-time CrossFit regionals athlete built his career around defining the standard of care in longevity medicine. Jimmy shares the full arc of his path from a three-sport young athlete through three ACL tears, into a spine surgery business that performed 100,000 procedures, and then into Agentis Longevity, a company built around acquiring the best longevity clinics in the country and unifying them under one consistent set of protocols. You will also get a full breakdown of the Longevity Quotient, the five-test battery Agentis uses to score every new patient, and hear how Jimmy and I built a custom Agentis x Boundless protocol for my listeners.
Jimmy St. Louis is a healthcare entrepreneur, operator, and former elite athlete dedicated to driving the standard of personalized health, longevity, and regenerative medicine.
