New Office Hours

After 50 years of caring for patients in our Clinton location, we have decided to consolidate our Maryland offices. We will be seeing patients in person in Waldorf and Alexandria only. We are seeing patients 4 days a week in Waldorf starting Monday, May 9th. Our Alexandria office hours are the same.

Immunotherapy continues to be by appointment only. No walk-ins will be accepted. We will be administering injections in Waldorf on Tuesday, Wednesday, and Thursdays by appointment. In Alexandria, injection hours will remain by appointment on Monday, Wednesdays and Fridays.

The health and wellness of our patients and staff remain our highest priority. We continue to require all patients over the age of 2 to wear a mask.

We are screening all staff & patients daily, sanitizing common areas, and maintaining social distancing.

We ask adult patients to come alone. Only one parent/guardian will be allowed in the office with a minor (patients under the age of 18).

We kindly ask that you NOT come in if you have been recently exposed to COVID-19 cases or have any symptoms of new onset loss of smell or taste, have a fever or chills, new onset cough, shortness of breath, or difficulty breathing, fatigue, or muscle aches.

"The doctors at this office are fantastic. They listen to your experiences and don't dismiss your own understanding of your symptoms. They take your lifestyle and preferences into consideration for your treatment. Also great with kids."

Congratulations Dr. Samee!

Join us in congratulating Dr. Samee for being recognized as a “TOP DOCTOR” in Northern Virginia Magazine, 2021.
