Coronavirus Announcement

We are now taking office appointments for annual physicals, chronic and acute illnesses. Please schedule by calling our office or through our website. Virtual visits are always available with all the providers as well for anyone not needing lab work. If you are exhibiting any symptoms of Covid-19 we ask you only schedule virtual visits.

Our patient’s health and safety is our highest priority, and we are taking all necessary precautions to keep our office safe and clean, including: Ensuring our office staff are prepared and have the appropriate personal protective equipment to safely care for in-person visits. Following proper office and medical cleaning routines, including thoroughly cleaning frequently touched surfaces after each patient visit. Screening all patients for any signs of a respiratory infection or potential exposure and taking appropriate actions to protect our patients and care team.

FACE MASKS ARE REQUIRED in the office. Patients without one will be turned away.

"My wife and I have been going to Dr. McMackin since our family moved to Wash DC three years ago. He has taken great care of us and drastically improved our overall health and wellness. He was put together a proactive plan to make sure I can address my health priorities and sought my input every step of the way. I like the no nonsense approach that very much accompanies the caring bedside manner. The whole process is always efficient and straightforward. I am especially thankful to the responsiveness to email questions even after hours. My family is very grateful especially during times of Covid."
