Dean Ornish, MD

Dean Ornish, MD, is the founder and president of the nonprofit Preventive Medicine Research Institute in Sausalito, Calif.  He is clinical professor of medicine at the University of California, San Francisco.  Ornish received his medical training in internal medicine from the Baylor College of Medicine, Harvard Medical School, and the Massachusetts General Hospital.  He received a BA in humanities summa cum laude from the University of Texas in Austin, where he gave the baccalaureate address. 

For more than 32 years, Ornish has directed clinical research demonstrating, for the first time, that comprehensive lifestyle changes may begin to reverse even severe coronary heart disease, without drugs or surgery. He directed the first randomized, controlled trial demonstrating that comprehensive lifestyle changes may stop or reverse the progression of early-stage prostate cancer.  His research showed that comprehensive lifestyle changes affect gene expression, “turning on” disease-preventing genes and “turning off” genes that promote cancer and heart disease. In collaboration with Nobel laureate Elizabeth Blackburn, PhD, he also showed that these lifestyle changes can lengthen telomeres, the ends of chromosomes that control how long we live.

He is the author of six best-selling books, including New York Times’ bestsellers Dr. Dean Ornish's Program for Reversing Heart Disease; Eat More, Weigh Less; Love & Survival; and his most recent book, The Spectrum. 

The research that he and his colleagues conducted has been published in the Journal of the American Medical Association, The Lancet, Proceedings of the National Academy of Sciences, Circulation, TheNew England Journal of Medicine, the American Journal of Cardiology, The Lancet Oncology, and elsewhere.
