Timothy J. Smith, M.D. has been studying and practicing alternative, functional, nutritional, and conventional healing principles for almost 50 years. He graduated from the University of Cincinnati College of Medicine in 1970, completing his internship at Presbyterian Hospital in San Francisco and residency in psychiatry, specializing in brain biochemistry, at the University of California, San Francisco and San Francisco General Hospital. He then trained to become a doctor of Traditional Chinese Medicine in San Francisco, Japan and China. He taught TCM to thousands of physicians at the University of California, Los Angeles. 

He designed and administered the first certifying acupuncture examinations for the states of California and Florida and joined the team that created the first national acupuncture certifying examination for physicians, served as president of the American Acupuncture Association, was a founding member of the American Academy of Medical Acupuncture, and was honored to be selected as a delegate member of the first group of American doctors practicing Chinese Traditional Medicine to travel to China as guests of the government in 1979. 

He established his general family practice in Berkeley, California in 1972, in which he integrated conventional medical practice with alternative modalities. In the 1980s and 90s he turned his attention from acupuncture to molecular, functional, nutritional, and anti-aging medicine. He published his bestseller Renewal: The Anti-Aging Revolution (Rodale, St. Martin’s) in 2000. Dr. Smith’s recent focus has been on the latest research developments in molecular, functional, and nutritional medicine and epigenetics, applied to the prevention and treatment of Alzheimer’s disease. His current book, Reversing Alzheimer’s, is based on this work.

Dr. Smith has been a member of numerous professional organizations, including the American Academy of Anti-Aging Medicine, the American Psychiatric Association, the American College for the Advancement of Medicine, the American Academy of Functional Medicine, and the Physicians Committee for Responsible Medicine.
