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.

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!

Diana Nguyen, RDH ardmore pa

Diana grew up in Broomall and currently resides in Ridley Park with her fiancé, Jay. She had an early exposure to the dental field during her sophomore year of high school when she attended Delaware County Vocational High School for dental assisting.

Diana enjoyed the meaningful connections and hands-on aspect of the dental field and went on to pursue dental hygiene at Manor College (fun fact: she was on the billboard on I-95 for Manor’s advertisement)!

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.
She’s excited to assist you in improving your oral hygiene at your next cleaning and hear all about your favorite restaurants!
