Administrative Team

Maryann Ammon

Accounts Payable/Bookkeeper

Before joining Thorndale Dental in February 2016, I had over 25 years of bookkeeping experience within the HVAC industry.  It has been a pleasure and privilege to work in an environment where both personal and professional excellence is the standard. 
Originally from Delaware County, my husband and I moved to Glenmoore, Chester County in 1991 and we have four grown children.  When I am not “crunching numbers”, I look forward to spending time with family.  I also enjoy gardening, cooking, antiquing, road trips as well as attending concerts and plays.


Stephanie DeForno

Clinical Administrator/Office Manager

Hello, my name is Stephanie.  I joined the Thorndale Dental Team in August 2007 as the Financial Coordinator.  In 2010 I took on the responsibility as the Clinical Administrator/Office Manager.  The dental field is a great occupation.  Coming to work each day is so rewarding when you are able to help transform a patient’s smile.  Everyone deserves the best of oral health.
I am married to Dr. Rich and we have four wonderful children between us.  My daughter is starting her own business/product line within the fashion/beauty industry.  My son is currently enrolled in college, majoring in Film Production.  He also takes flying lessons at our local airport and races motocross. 
In my spare time I relax with my family, two Great Danes, tending to our chickens, cooking, gardening, and traveling.  I also enjoy skiing most of the winter.  I look forward to seeing you at your next dental visit.

Noelle Means

New Patient/Marketing Coordinator

Hi, my name is Noelle.  I grew up in New Zealand but recently made my home in Chester County.
I have enjoyed careers in both Real Estate and Health and Wellness.  My new occupation in the Oral Health Field continues to satisfy my calling to connect with people and help make their lives better.  Thorndale Dental is a vibrant and exciting workplace that I find both stimulating and rewarding. 
On a personal level, I have one daughter who is happily pursuing her education in biodynamic agriculture.  I am interested in the visual and performing arts, music and nature.  In my spare time you will find me outside with camera in hand, hiking, biking or playing my drum.
I’ve enjoyed meeting and discovering new people all my life and I look forward to learning about you.
