PhysioAge was founded in 1997 in New York City. We focus exclusively on bioidentical hormone replacement therapy and age-management medicine. Our bioidentical hormone doctors are able to detect pre-clinical disease states and measure an individual's rate of aging using a next-generation physical exam.

Our Salt Lake City partner location opened August 1, 2011. Dr. Jeff Nelson has been trained by our founding physicians to practice the same medicine.
Our Grand Rapids location opened November 2011, where Dr. Steve Lasater focuses exclusively on bioidentical hormone replacement therapy and age-management medicine.
Dr. Lasater received his initial training in the principles and practice of bioidentical hormone replacement from Neal Rouzier MD, of Palm Springs, California. (Dr. Rouzier's book, How to Achieve Healthy Aging, is considered a landmark guide for physicians and patients in this field.) Dr. Lasater has further received additional training in hormone therapy and age-management medicine from Joseph Raffaele MD and Ronald Livesey MD of PhysioAge's New York City office. He has been practicing bioidentical hormone replacement in Grand Rapids since 2009.
PhysioAge New Jersey is led by Dr. Sammy Masri .
