Dr. Yoon completed her orthodontic and pediatric dentistry residencies at the University of California Los Angeles (UCLA), the nation’s pre-eminent program of its type. She also earned her Doctor of Dental Surgery and Master of Science degree, completing extensive research in Obstructive Sleep Apnea (OSA) at UCLA.

She is currently an adjunct assistant professor of Stanford Sleep Medicine Center at Stanford University and an assistant professor in Orthodontics at University of Pacific. She founded Pacific Ortho-Dental Sleep Medicine Fellowship at University of Pacific and serves as a program director. She is also a clinical associate at Tufts University School of Dental Medicine and serves as a co-director of Pediatric Dental Sleep Mini-residency program at Tufts University.

Dr. Yoon has established World Dentofacial Sleep Society and serves as a founding president. Dr. Yoon lectures internationally, leads workshops for professional audiences and provides expert clinical consultation to health professionals worldwide. She is also a diplomate of the American Board of Dental Sleep Medicine and a diplomate of the American Board of Orthodontics.

Using state-of-the-art technology, Dr. Yoon is committed to achieving clinical excellence and ideal case results. She is an Invisalign Diamond Plus provider, which is only bestowed to the top 1% of Invisalign doctors. Dr. Yoon’s field of expertise includes the effective utilization of orthodontic Temporary Anchorage Device (TAD) to minimize surgery and maximize esthetic successful outcomes. She practices the full scope of non-surgical and surgical orthodontics from pediatric to geriatric population for airway management including growth modification, pediatric palatal expansion, customized Miniscrew-Assisted Rapid Palatal Expansion (MARPE), Distraction Osteogenesis Maxillary Expansion (DOME), Orthodontic treatment for Maxillomandibular Advancement ( MMA ), clear aligner therapy and oral appliances for sleep apnea.

She has developed a pioneering Distraction Osteogenesis Maxillary Expansion (DOME) technique for the treatment of obstructive sleep apnea and has co-authored many chapters in several leading textbooks. She also proposed growth modification protocol for children with sleep disordered breathing. With this guideline of the craniofacial growth and development modification, health providers can take advantage of the therapeutic appliances that can make a substantial change in a patient’s growth pattern during maturity.

As a proud mother and loving wife, Dr. Yoon is a firm believer in strong family core values. She carries this philosophy into her practice, giving her patients the care and attention they deserve just like a part of her family.
