Reception and Customer Service

Denise Bellisario RDH, BS Office Manager


I have been in the dental field for 40 years. I grew up in Philadelphia, and after high school, I went to Expanded Functions Dental Assistant school for 2 years. After being a Dental Assistant for 4 years, I decided to go back to Dental Hygiene school. I graduated from Dental Hygiene school in June 1982, then continued on to earn my Bachelors in Science/Dental Hygiene Education. I’ve been married for over 37 years, and I’m the office manager for our practice. I find working with my husband, in our practice, is extremely rewarding as we both take pride in what we do.

In my spare time, I love to golf, spin, do Pilates, and go on long walks at the beach. I also love to spend time with my son and my daughter when they are home.
