Mark Gunderson, MD specializes in one of the fastest growing medical specialties in the world: age management medicine (AMM). The field aims to extend lives by optimizing body composition and reducing inflammation, both with healthy lifestyle choices and techniques such as bio identical-hormone-replacement therapy. Dr. Gunderson's extensive knowledge in these areas stems from years of work in emergency medicine, his diplomate status with the American Board of Emergency Medicine and the American Board of Anti-Aging Medicine, and certification in AMM by the Cenegenics Medical Institute. He shares health advice as the host of a weekly radio program called Health Matters with Dr. Mark Gunderson—a spinoff of the Nevada Matters talk radio show hosted by Eddie Floyd on KKFT 99.1 FM—and as the medical advisor for Nina Cucina, an online cooking club that teaches members how to create healthy, gourmet meals.

At the Age Management Institute, Dr. Gunderson and his staff combat age-related diseases with customized programs. They use advanced diagnostic techniques such as body composition analyses and state-of-the-art hormone and blood panels. His Accelerated Weight Loss Program incorporates HCG injections, a low-calorie diet, and weekly coaching sessions to foster success. Certified plastic-surgery nurse Renee J. Hinojosa is the director of medical aesthetics at the institute; she combats wrinkles with Botox and chemical peels, and uses a Fotona laser to clear complexions of acne or permanent-marker IOUs left by the tooth fairy.
