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.

I was born and raised in South Jersey. I moved to PA in 2010 when I started my first job working in a dental office. I continued my education by attending Harcum College for the Expanded Functions Dental Assisting program, which I completed in the Spring of 2013.

When I am not in the dental office I enjoy cooking and baking, I love to try new recipes! I also enjoy running, hiking, and doing various outdoor activities with my fiancé. We hope to one day start a family.

Marisa, RDH  – Registered Dental Hygienist

Marisa was born and raised in Delaware county and started her career in the dental world back in 2013 when she attended Delaware county technical school for dental assisting her junior year of high school. She started working for a dental office as a dental assistant and found her love for dentistry grew more and more.

   She then pushed herself to go to hygiene school at Harcum College where she got her degree in dental hygiene in 2018. She was inducted into the dental hygiene honor society, Sigma Phi Alpha. She still has her eyes on one day maybe becoming a dentist but takes pride in being a hygienist who is self motivated and ambitious. She enjoys the one on one interaction hygiene allows for and her patients appreciate her compassionate and comforting demeanor. Marisa’s first priority is patient care and when she joined  Dr. Bellisario’s office… she knew she was in the right place.

    Outside the office, Marisa enjoys shopping, working out and spending time with her family and her pets Bella, Gracie and Max. She loves spring and summer but summer most of all just to take trips to the beach.


Anne Marie, RDH – Registered Dental Hygienist

Anne Marie joins our team all the way from Lexington, KY. She recently re-located with her boyfriend Josh, while he completes a residency in Oral and Maxillofacial Surgery at the University of Pennsylvania.

Growing up, she would work after school answering phones and cleaning rooms at the dental office where her mom worked. Early beginnings in dentistry inspired the thought of Anne Marie becoming a dental hygienist, just like her mom. She attended the University of Louisville (go Cardinals!) and obtained a Bachelors Degree of Dental Hygiene in 2019. In dentistry, she most enjoys helping patients develop a home care routine that they feel confident about.

Outside of the office, Anne Marie enjoys reading, needlepoint and watching football. On the weekends you can find her and Josh exploring the city, or visiting family in Kentucky or Virginia Beach. She looks forward to meeting you at your next dental cleaning!

During her free time, Diana enjoys hanging out with her friends and family, painting, and baking. She calls herself a big “foodie” and loves trying new foods, especially during her travels.
