Diane Rothstein

Office Manager/Patient Care Coordinator

Diane Rothstein has been with us at A R Periodontics since July 2008. Like so many others, a career in dentistry is her calling. In high school, Diane worked part-time as a dental assistant for her local dentist. She attended BOCES in Valhalla, NY, where she received her certificate in dental assisting. She worked as a dental assistant for 10 years before transitioning to office manager. Diane has kept her skills current and continues to maintain a license for dental radiology in New Jersey. Diane moved from New York to New Jersey in 2005.

As our office manager and patient care coordinator, Diane is the face of A R Periodontics. She is the smile that will greet you when you walk into our office. Diane will help you with appointment scheduling and assist in coordinating treatment between our office and other dental offices when necessary. Over the years, Diane has learned much about dental insurance and will do her best to answer all your questions. She will review treatment plans with you, discuss your insurance coverage (including benefits, limitations, and copayments), and present payment options.

In her spare time, Diane enjoys exercise, reading, watching NASCAR and the NJ Devils hockey, and spending time with her cats, Oliver and Chester.
