DIANE ROTHSTEIN | Office Manager, Patient Care Coordinator

DIANE ROTHSTEIN | Office Manager, Patient Care Coordinator
Diane Rothstein has been with us at A R Periodontics since July 2008. Like so many others, 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 hanging up her scrubs to become an office manager. Diane has kept her skills fresh 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. Hers 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 go over treatment 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 NJ Devils hockey, and spending time with her cats, Tiger and Smokey.
