We were the first to propose preventive, proactive, personalized, data-driven health, rather than reactive health. We were the first to offer diagnostics and interventions, from stress testing to DEXA body composition analysis, biological age measurement, personalized nutrition and exercise plans, and hormone replacement therapies, to healthy individuals to promote optimal health, regardless of age. We were the originators of the medical specialty in age management. We were the first to write a textbook on this medical specialty and the first to certify physicians in it. We founded A4M. We have been doing what is new today for more than 25 years. In short, Cenegenics was the origin of longevity medicine.
