Dr. Rod Willey, DDS, D.ACSDD, D.ASBA

Dr. Willey is a General Dentist and Diplomate 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.

He is the founder and developer of Koala® Center For Sleep & TMJ Disorders and follows strict medical and dental guidelines for treatment and medical insurance reimbursements for patients. Dr. Willey is a national speaker for conventions and workshops with colleagues and students. Other professional memberships include the American Academy of Dental Sleep Medicine and the Academy of Craniofacial Pain.

She is excited to work with you and find the most effective treatment method that you will be comfortable using for consistent, long-term benefits.

Some of Nicole’s additional interests, outside of her very busy family and adorable dogs, include: nutrition, exercise, boating and the great outdoors. We think you will really enjoy working with Nicole to achieve your best sleep and TMD health!
