Associate Medical Director

As a pioneer in the field of Preventive and Regenerative Medicine, Ron Rothenberg, M.D., was among the first group of physicians to be recognized for his expertise in this rapidly emerging field. The 10th M.D. in the world to be recognized by the American Board of Anti-Aging and Regenerative Medicine, 

Dr. Rothenberg has always challenged traditional medicine’s ability to embrace new paradigms. After graduating from Columbia University, College of Physicians and Surgeons, in 1970, Dr. Rothenberg practiced medicine and studied indigenous healing in the Amazon Basin for several years. He then performed his residency in Emergency Medicine at Los Angeles County-USC Medical Center. At the time, the specialty of Emergency Medicine (like Anti-Aging and Regenerative Medicine) was not widely recognized by the medical community. Dr. Rothenberg was passionate about the field, and went on to teach and practice Emergency Medicine. He is a former Full Clinical Professor of Preventive and Family Medicine at University of California, San Diego School of Medicine.

Dr. Rothenberg has educated over 25,000 physicians who have attended his continuing education seminars. As the creator and director of the Postgraduate Institute for Primary and Emergency Physicians at University of California, San Diego, School of Medicine he helped create the specialty of Emergency Medicine by training physicians as this field emerged. Over the past 10 years he lectured worldwide on Preventive and Regenerative Medicine, Hormone Optimization and Stem Cells. In addition to his work in the field of Anti-Aging and Regenerative medicine, Dr. Rothenberg remains an Attending Physician and at Scripps Memorial Hospital in Encinitas, California. With the health and vitality that he had when he was much younger, Ron Rothenberg continues to enjoy his other passions: his wife, his three children, surfing, skiing, mountain biking, and Baja California.
