Location and Directions


To all our patients,

Thank you for choosing Pennsylvania Dermatology Group.

As healthcare providers, the well-being of our patients and staff is our utmost concern.

Due to the COVID-19 pandemic, we have temporarily closed our office for routine visits and the majority of surgical procedures. This decision is based on guidance from state and federal authorities as well as current best medical practices.

Until further notice, our physical office will remain open for a limited number of appointments to see patients with truly urgent concerns. Our hope is to preserve emergency and urgent care resources to address our current public health crisis.

We have also begun to see patients using telemedicine, which will enable us to safely provide continuity of care for patients with certain conditions without potential viral exposure. If you are interested in scheduling a virtual appointment, please call our office at (215) 947-7500 between 8am and 3pm Monday-Friday to speak with a member of our team.
