Welcome to Our Practice

Dermatology Care in Northern Virginia

In the wake of recent tragic events happening in our country, our practice wants to acknowledge, stand by and support all of our members and their patients who have been discriminated against, harmed or treated unjustly based on the color of their skin.

As healthcare providers, our professional vocation is to protect and preserve human life. We believe this principle should be enshrined as an essential human right. Our practice is deeply committed to inclusivity and equality, and we are prepared to do everything in our power to put those values into action. 

We strive to provide the highest quality patient care in a responsive and caring environment. Our office provides a full range of dermatology services for all ages, including specialized procedures, such as Mohs Micrographic Surgery for the treatment of complicated skin cancers and cosmetic procedures such as hair restoration. Services and treatments we offer include acne, hair loss, skin care, skin cancer, chemical peels, and more.

Washingtonian Magazine has named Dr. Sebastien "Outstanding Physician" since 2002.

Thank you for visiting us online and we look forward to assisting you with your skin care needs.
