Dr. Felix Liao, is a leading authority on the mouth-airway-fatigue & pain connections and is the trailblazing leader behind the Airway Mouth Doctor (AMD) movement. Winner of the Global Summit Institute’s “Lifetime Achievement Award,” Dr. Felix is revolutionizing dentists’ role in improving overall health as AMDs. He discovered that up to 80% of muscle aches, pains, poor sleep, chronic fatigue, teeth grinding, and mental issues stem from the mouth, for which Dr. Felix coined the term Impaired Mouth Syndrome. Many thousands of patients have been helped to get their lives back through AMDs who have trained with Dr. Felix

Born in Taiwan and raised as a scholar-athlete-pianist, Dr. Felix was educated in the United States, first as an engineer and later as a dentist. While attending dental school, his engineering and East-West mindset lead him to the pivotal question: “Why would the body grind down its own teeth?!” This question nagged him into a career-long quest to find the root cause, discovering it was: airway obstruction during sleep from a structurally impaired mouth.

An Impaired Mouth can and does lead to a surprisingly vast range of medical, dental & mental symptoms. Over 90% of all patients live with Impaired Mouth Syndrome and don’t even know it. That’s because Impaired Mouth Syndrome is missing on the radars of nearly all doctors and dentists.

Dr. Felix's consistent successes in treating Impaired Mouth Syndrome led to him developing and directing the Airway Mouth Doctor® (AMD) training program, which is churning out a new breed of dentists who are expertly trained to successfully upgrade body health naturally, by diagnosing Impaired Mouth Syndrome and treating it with his Airway Facial Epigenetics™ method.

Since then, Dr. Felix has written his bestselling book, 6-Foot Tiger (tongue) 3-Foot Cage (jaws) as well as contribute landmark cases that have been documented in 6 journal articles! He has gone on to pen four more Amazon bestsellers.

In addition to directing the AMD training program and continuing to work with patients, Dr. Liao provides keynotes and interviews worldwide on Impaired Mouth Syndrome, building bridges between dentistry and medicine, healing the healers, and building proactive health by bringing on Best Face in both children and adults.

Dr. Felix is also the founder of Wellness Fun Tours® that are dedicated to teach how to eat for health and enjoy eating, which is how to make Wellness FUN! He loves sharing his passion with the world over. Residing in Falls Church, Virginia, he still maintains his practice where patients fly in from around the globe. Dr. Felix’s son Franklin is a chef dedicated to producing healthy, home-cooked meals based on Dr. Felix’s Licensed To Thrive book which has contributed to Liao’s beautiful grandchildren Hillary and Camila.
