About Dr. Gierie

Dr. Bill Gierie is passionate about orthodontics. He believes his life was changed forever when he received the gift of straight teeth. Fascinated by the process and the amazing results, he was drawn to the profession. "I don’t feel like I’ve worked a day in my adult life because I love what I do," says Dr. Gierie.

His love of orthodontics has led him to share his knowledge with others. As part of the Invisalign® Speakers Bureau, Dr. Gierie is a sought after speaker and lectures internationally, teaching other orthodontists how to use the Invisalign system and sharing his latest innovations. As an associate adjunct professor in the Department of Orthodontics at the University of North Carolina he shares his passion with young orthodontists in training.

Dr. Gierie is a member of the Invisalign North American Clinical Advisory Board and is one of only 7 members in the world to serve on this board whose mission is to provide feedback on product direction and development.  

Dr. Gierie is a member of the American Dental Association, American Association of Orthodontists, the Academy of Laser Dentistry, the North Carolina Dental Society and the Wilmington Tri-County Dental Society (where he served as a past president). When not practicing orthodontics or lecturing Dr. Gierie enjoys reading, computers, chess, cooking, boating, paddleboarding, cycling and being outdoors whenever possible. 

Dr. Gierie has a daughter and two sons.
