William Sears, MD, survivor of colon cancer and leukemia, has been advising busy parents on how to raise healthier families for over 40 years, and now turns his attention to the specialty of lifestyle medicine. He has served as a voluntary professor at the University of Toronto, University of South Carolina, University of Southern California School of Medicine, and University of California: Irvine. As a father of 8 children, he coached Little League sports for 20 years, and together with his wife Martha has written more than 40 books and countless articles on parenting, nutrition, and healthy aging. He serves as a consultant for TV, magazines, radio and other media, and his website AskDrSears.com is one of the most popular health and parenting sites. Dr. Sears and his contribution to family health were featured on the cover of TIME Magazine in May 2012. He is noted for his science-made-simple-and-fun approach to family health.
