He worked for over five years as on-site staff dentist at the hospital, providing essential routine and emergency care to the community. During this time he was also a volunteer Assistant Clinical Professor of Dentistry at Columbia University.

He is Past-President of the Eastern Dental Society of Manhattan, and served for a number of years as a Member of the Board of the New York County Dental Society component of the New York State Dental Association, a member society of the American Dental Association.
