Dr. Willey is a General Dentist and diplomat with the Academy of Clinical Sleep Disorders Disciplines, a Diplomate of the American Sleep and Breathing Academy, and serves on the Board of Directors for the Dental Division of the American Sleep and Breathing Academy.
He has dedicated his practice to treating sleep-disordered breathing, snoring, obstructive sleep apnea, and oral facial pain (TMD). His career path has taken him from general dentistry to the study of functional orthodontics at the United States Dental Institute, to Neuromuscular Occlusion from the prestigious Las Vegas Institute for Advanced Dental Studies to treatment of Obstructive sleep Apnea with Oral Appliance Therapy. All these areas deal significantly with the neuromuscular positioning of the lower jaw and have proven to be a natural progression in his post-graduate studies.

Dr. Willey is a national speaker for conventions and workshops with colleagues and students.
