Graduate Orthodontic Program Faculty

Teaching Staff

The orthodontic faculty is presently comprised of 21 full-time or part-time members, most of whom are practicing orthodontists. This broadly-based group of individuals (they have advanced degrees from several different universities) is substantial (5.0 full-time equivalents) and has many strengths and talents. Many are Diplomates of the American Board of Orthodontics, several hold or have held high offices in national or regional dental and orthodontic associations, and collectively the faculty has over 400 years of experience in clinical orthodontics. Many members are internationally known for their research, teaching, and clinical ability. Several visiting lecturers also participate in the education of our students. Because of the continued study and diligence of this dedicated faculty, our program stands today as a leader in the training of orthodontists.
