Meet the Hygienists

Allentown PA Dentist


Liz graduated from the dental hygiene program at Northampton Community College in 1986 and has been with Cetronia Dental ever since. In addition to finding satisfaction in helping patients maintain their oral health, she loves the fact of having the privilege to serve three to four generations of the same families over the years. So often she feels like it is catching up with old friends at patients' recall appointments. She is married to Kenny and they have two cats. In her spare time, she enjoys gardening, biking, playing the piano, and waterskiing.


Dee has been an employee at Cetronia Dental for over 35 years. She graduated from Northampton Community College in 1991 and she enjoys her job educating and encouraging patients to achieve optimal oral health. Dee is married and has two college aged children. In her spare time, she enjoys walking, vacationing and spending time with her family.


Jennifer graduated from Northampton Community College as a dental hygienist with a local anesthesia license in 2014. Dental hygiene, however, was not her first career path. She worked in a nursing home with dementia/Alzheimer's patients for eight years before entering the dental field. As a hygienist she enjoys what she does, and it shows. She educates patients on their dental health and also has the ability to connect to every patient no matter what their age. In her free time, she enjoys spending time with her two children Alexia and AJ and her rescue pets.
