He also holds a Diplomate from the American Breathing and Sleep Academy and the American Board of Dental Sleep Medicine. He is also a lecturer at OLLI at UC Irvine on topics of dentistry and sleep apnea.

Dr. Lee first became interested in TMJ Dysfunction and Sleep Apnea Management due to his own problems battling the syndromes. Realizing simple “night guards” and “snore guards” were not the answer, Dr. Lee has intensely studied, researched, and joined organizations that provide excellent solutions for these problems. He has a particular interest in TMJ dysfunction and how it relates to upper airway resistance syndrome (UARS). The syndrome is often linked to anxiety, insomnia, fibromyalgia, and headaches.

Dr. Lee is so fortunate to have worked with Dr. Riley and the expertise he brings. The best part of his job is providing his patients with a life-improving impact. He has also been a part of a few medical mission trips with his church. He has also been a part of a few medical mission trips with his church.
