He is a graduate of Harvard University and Baylor University College of Medicine, and one of a very few doctors board-certified in four specialties: Sports Medicine, Allergy and Immunology, Pediatrics and Pediatric Immunology. Dr. Mirkin's latest book is The Healthy Heart Miracle, published by HarperCollins. He is author of the bestselling The Sportsmedicine Book, the first book on that subject; and wrote the chapter on sports injuries for the Merck Manual. His daily short features on fitness have been heard on CBS Radio News stations since the 1970's. He did his residency at the Massachusetts General Hospital and over the years he has served as a Teaching Fellow at Johns Hopkins Medical School, Assistant Professor at the University of Maryland, and Associate Clinical Professor in Pediatrics at the Georgetown University School of Medicine. Dr. Mirkin has run more than forty marathons and is now a serious tandem bike rider with his wife, Diana.

Diana Mirkin has taught thousands of people how to make healthy foods taste delicious through her cooking school, cookbooks and online recipes. She is co-author with Dr. Mirkin of The Healthy Heart Miracle, The Whole Grains Cookbook, The 20/30 Fat and Fiber Diet Plan, and Fat Free, Flavor Full. She has developed hundreds of recipes that follow Dr. Mirkin's guidelines for healthy eating, featuring whole grains, beans, vegetables and fruit. Diana is a graduate of Vassar College and has an MBA from Loyola College. When she's not writing or inventing tasty new recipes, she's usually out riding the tandem bicycle or her trike, gardening or exercising her dogs.
