Gannon Lee Mission ViejoDr. Lee is an Orange County native that has been practicing dentistry for well over fifteen years. After nearly a decade in his private practice in Encinitas, California, Dr. Lee decided to relocate back to Orange County. It was a very difficult decision to leave good friends, patients, and relationships he’s built up over the years. However, he and his wife just welcomed a baby girl to their family and they realized it was the best choice to relocate back to be closer to family. Dr. Lee was a former Junior Olympic swimmer and in his free time, still enjoys swimming. He is also an avid Los Angeles Lakers fan and cheers for his USC Trojans. Aside from practicing dentistry, he and his wife are busy raising two wonderful girls: Elise and Kathryn.

Dr. Lee’s commitment to lifelong education means that he is constantly evaluating emerging dental methods and technologies in order to provide his patients with the best results in the least invasive manner. He is a member of the world-renown Spear Study Group. He places a high emphasis on comfort and serving each patient individually. 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. All of this commitment ensures you the highest level of care, both today and tomorrow.

He is a member of the American Dental Association, American Academy of Craniofacial Pain, American Academy of Dental Sleep Medicine. He has furthered his education by becoming board certified and holds a Diplomate from the American Breathing and Sleep Academy.
