A Note to Our Patients Regarding COVID-19:

We care about the safety of our patients and our community during this pandemic.

Due to the COVID-19 virus we are limiting in-office patient visits to those with urgent issues. Urgent issues include any lesions of concern for skin cancer (especially melanoma) and painful or disruptive rashes and lesions that might otherwise lead to a visit to an emergency room or urgent care center. 

We are also instituting tele-dermatology (using the camera on your cellphone or computer) to serve our patients' needs.

Due to these changes, beginning April 6, 2020, we will be restricting our office hours to 8:30am to 3pm Monday to Friday.

If you have any questions or concerns, please feel free to contact our office at 240-246-7417 during the hours above. If you would like to schedule a tele-dermatology visit with our doctor, please call the office.

We hope all of our patients will stay safe during this time, and we wish you and your family a healthy spring.
