Dr. Roizen is the Cofounder of RealAge Inc, which was sold in 2006, but still Chairs its Scientific Advisory Board. He is 72 calendar years of age (2018), but his RealAge is 53.8.

Dr. Roizen is a Past Chair of a Food and Drug Administration advisory committee and a former editor for six medical journals. He has published more than 185 peer-reviewed scientific papers, 100 textbook chapters, 30 editorials, and four medical books (one, a medical best-seller), and received 13 U.S. and many foreign patents. One of the drugs he co-invented and developed (licensed to Progenics and Wyeth Corp.) has been approved by the FDA.

After nine years on the faculty at the University of California, San Francisco, he chaired the top-10-rated Department of Anesthesia and Critical Care at the University of Chicago. He then became Dean of the School of Medicine and Vice President for Biomedical Sciences at SUNY Upstate. After serving as CEO of the Biotechnology Research Corporation of Central New York, he accepted a position as Chair of the Anesthesiology Institute at Cleveland Clinic, responsible for over 180 operatories, 124 critical care beds and 28 pain therapy intervention units.

In 2007, Dr. Roizen was named Chief Wellness Officer at Cleveland Clinic, the first such position in a major healthcare institution in the United States. Dr. Roizen also served as founding Chair of the Wellness Institute at Cleveland Clinic from 2007 to 2017.

His first general-audience book, RealAge: Are You as Young as You Can Be? (HarperCollins Publishers) became a #1 New York Times bestseller and was awarded the Best Wellness Book of 1999 by the Books for a Better Life Awards. RealAge has been translated into more than 20 languages and was #1 in four other countries, displacing Harry Potter for 7 days as #1 on Amazon. Other books include the New York Times bestseller The RealAge Diet: Make Yourself Younger With What You Eat (HarperCollins), written with Dr. John La Puma, Cooking the RealAge Way (Harper Collins), also with Dr. La Puma., and The RealAge Makeover (HarperCollins). His book, YOU: The Owner’s Manual (HarperCollins), written with  Health Corps founder Dr. Mehmet Oz, debuted in May 2005 and became a #1 New York Times bestseller (sold more than 2.7 million hardcover copies worldwide; was the #2 best-selling book published in 2005-- displacing Harry Potter for 35 days as #1 on Amazon and BN.com.).

Dr. Roizen still practices internal medicine, using the RealAge metric to motivate his patients. He routinely takes patients at the Cleveland Clinic Wellness who are in the midst of struggling with tobacco, heart, diabetic or arthritic problems and coaches them with simple (but persistent) lifestyle changes to be able to live, feel, look and be years younger. He really enjoys getting them to throw away their medications when they no longer need them, but teaches the role of  food and other simple steps in reversing disease processes. Cleveland Clinic Wellness aims to elevate preventive care and wellness as a core brand of Cleveland Clinic and a core value we teach our patients and employees.
