Faculty/Attending Dentists

The General Practice Residency is directed by Mary L. Voytus, D.D.S, who is full-time at HackensackUMC Mountainside. In addition, general dentists and specialists in all disciplines play a significant role in resident education. Since these faculty consist of dentists who are all in private practice they are able to give the residents an excellent perspective on transition to a private practice setting on completion of the residency. Residents and faculty work collaboratively for the benefit of patients, the community and the resident's personal and professional growth.
