One of the physicians of our office is available for urgent phone consultation at all times when our office is closed, such as evening, weekends and holidays.  The on-call doctor can be reached through our answering service at 240.638.9739.  You can expect a return call promptly.  In the event that you have not received a callback within 20 minutes, please call back as we may have received an incorrect number or had difficulty getting through to you.  We ask that you use good judgment and consideration in calling after hours.  We are happy to respond to your call for acute illness and emergency.  Unnecessary calls, however, only detract from the service we can render to others with serious problems.
