What our patients are saying about us..

"I appreciate my physician, dental & other medical offices to have a level of professionalism and this office fits my above standard criteria. I am greeted by my name, staff are courteous and my appointment times are always respected. I picked this office through the Alumni Network of Temple University-Dr. DeFinnis lived up to his reputation. Since I have been a patient, I have recommended countless others who were Alumni & Non-Alumni."

~Shane J.

"I thought my gum was infected which was the reason for the visit. Upon examination it was not infected just irritated. The doctor explained that I was flossing to rough which irritated my gum. I like that he offers suggestions to help with my irritation."

~Kathy B.

"Serena is the hygienist who I had at Wynnewood Dental Arts. She is excellent. Very attentive, very gentle, very through and very sweet. The dental equipment at Wynnewood Dental is state of the art. From the waiting room to the dental chair everything is very, very clean. Everyone who works at Wynnewood Dental are very caring and gracious. It's not painful at all to go to this dental practice!!"
