Clinic Staff

The Children’s Dental Clinic is housed in a space generously donated by Dr. Neal Neumann, DMD, near Gateway Shopping Center in Wayne, PA. The Children’s Dental Clinic operates once a week on Thursdays by appointment only during the academic year.

When you first come to the clinic, you will be greeted by the clinic supervisor who also coordinates appointments and transportation. You will then be seen by the dentist for your treatment and care.
