TELEMEDICINE APPOINTMENTS AVAILABLE!

COVID-19 UPDATE: 8/16/2021
All patients must wear masks to their appointment, regardless if vaccinated or not.

We are pleased to announce that, in accordance with state and local guidelines, we are currently offering in-office appointments for both emergent and non-emergent visits. We do, however, continue to recommend the use of our TELEDERMATOLOGY (virtual visits) when appropriate and possible for our patients. This option allows our patients to receive the care they need without coming into the office. If you are interested in this option, we encourage you to call the office to inquire about scheduling.

Whalen Dermatology provides medical and cosmetic care to patients of all skin types, ages, ethnicities and conditions. We serve the greater Pittsburgh area with state-of-the-art equipment and technologies. A patient-centered approach helps us to provide the most comprehensive care plans and quality treatments for common and uncommon skin conditions. We look forward to caring for you and your family at your next visit.
