About Pediatric Dental Associates

Pediatric Dental Associates has been caring for the dental health of children and communities throughout Greater Philadelphia and Southeastern Pennsylvania since 1975.


At Pediatric Dental Associates, we know that excellent dental experiences start with excellent dentists.


Dr. Philip Siegel and Dr. Mark Goldstein founded Pediatric Dental Associates (PDA), at Episcopal Hospital in Philadelphia. Pediatric Dental Associates opened its second office in Northeast Philadelphia in 1978. Over the years, Pediatric Dental Associates expanded its ability to provide comprehensive pediatric dental care for infants, children, and teenagers throughout the region with additional offices on the main campus of Temple University Hospital, Ambler, and Southampton. In 1988 Dr. Michael Rosenbaum joined Pediatric Dental Associates.

In 1995, Pediatric Dental Associates partnered with Episcopal Hospital — now part of Temple University Health System — to create the Advanced Education Residency in Pediatric Dentistry, training future generations of pediatric dentists.

Now, with the help of partners Dr. Sharon K. Hamilton, Dr. Kim Thomas, Dr. Alegria D’Agostino, Dr. Noah Quinn and Dr. Paul A. Bahn, III along with our expertly trained dentists, staff, and residents, we are constantly evolving to meet the changing needs of our patients and families. Our commitment is to continually raise the standards for pediatric dental care, professional education, and childrens’ advocacy throughout Greater Philadelphia and Southeastern Pennsylvania.
