Dean Ornish, M.D., is the founder and president of the non-profit Preventive Medicine Research Institute and Clinical Professor of Medicine at the University of California, San Francisco.  Dr. Ornish received his M.D. from the Baylor College of Medicine, was a clinical fellow in medicine at Harvard Medical School, and completed an internship and residency in internal medicine at the Massachusetts General Hospital.  He earned a B.A. in Humanities summa cum laude from the University of Texas in Austin, where he gave the baccalaureate address.

For over 35 years, Dr. 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.  Recently, Medicare agreed to provide coverage for this program, the first time that Medicare has covered a program of comprehensive lifestyle changes.  He directed the first randomized controlled trial demonstrating that comprehensive lifestyle changes may stop or reverse the progression of early-stage prostate cancer.  His current research showed that comprehensive lifestyle changes affect gene expression, “turning on” disease-preventing genes and “turning off” genes that promote cancer and heart disease, as well as increasing telomerase, an enzyme that lengthens telomeres, the ends of our chromosomes which control aging (in collaboration with Dr. Elizabeth Blackburn, who was awarded the Nobel Prize in Medicine in 2009).

He is the author of six books, all national bestsellers, including: Dr. Dean Ornish’s Program for Reversing Heart Disease; Eat More, Weigh Less; Love & Survival; and his most recent book, The Spectrum.
