Dear Valued Patient,

In order to keep the community as safe as possible, we have implemented NEW OPERATING POLICIES. Updated guidance from the Centers for Disease Control (CDC) is still recommending the use of telehealth.  Most of our existing patients can be evaluated using VIRTUAL VISITS.  New patients will also be evaluated via a virtual visit  and if necessary, we will schedule you for in person allergy testing. If it is deemed necessary to come into our office, we ask that you bring your own pen and you must wear a face mask if you are older than 2 years of age. Minor patients are allowed one adult guardian to accompany them.

INJECTION HOURS are suspended in the Clinton office until further notice. We will begin allergy injections by appointment only on Mondays in Alexandria starting 6/1/20 and on Thursdays in Waldorf starting on 5/28/20.
