Dr. William Hang


Dr. William Hang graduated in 1970 with a BS and a DDS with honors from the University of Illinois. He received the Alpha Omega Award for graduating as number one out of a class of 92 and is a member of Omicron Kappa Upsilon National Dental Honor Society.

William began his career in dentistry as a general dentist in the United States Air Force before attending orthodontic training at the University of Minnesota. Upon graduation he then served as Assistant Professor of Orthodontics at the University of Minnesota before establishing orthodontic practices in Vermont and then California.

William is a leading speaker at local, national, and international conferences on topics including the Orthotropics® technique, orthodontics and the Posterior Airway Space, guidance of tooth eruption and prevention of tooth impaction, facial esthetics, obstructive sleep apnea’s relationship to facial development, and the reversal of previous orthodontic retraction often involving re-opening of extraction spaces.

He has committed his career to advancing a paradigm of thinking in orthodontics that rejects traditional retractive techniques in patients of all ages. His Face Focused® treatment techniques are designed to: develop the jaws forward, never backward; work toward proper facial balance; create pleasing facial appearance; protect and/or expand the airway; and produce broad smiles that are complete to the corners of the mouth.

When it comes to orthodontics William does not believe that one treatment can fit every patient. Over the years, experience has taught him that the easier way to treat is not always the best way to treat.
