our concierge model

Our concierge practice enrolls a limited number of patients, many of whom we’ve known for decades. By keeping our panels relatively small, we can provide longer visits, offer same or next day appointments and guarantee access to a physician on a 24/7 basis, through phone and email. We offer in-house lab and other diagnostic testing, with referrals to outside facilities when needed.

We are committed to providing you personalized attention and seamless experience with our team. When you call our office, you will always reach one of our team members, and not be put through a phone tree. Your requests will be handled quickly and efficiently. We will assist you with referrals both within and outside the DC area.

Accepting New Patients

I cherish the opportunity to learn my patients’ stories, and to be allowed into their lives, something I continue to find amazing and wonderful. I am dedicated to providing exceptional care using my extensive medical training and compassionate approach, and prioritize building trusting relationships and fostering open communication.

I received my MD from the University of Texas Medical Branch School of Medicine and an MS degree in preventive medicine from the University of Texas Health Science Center at San Antonio. I’ve been a professor of clinical medicine at the Johns Hopkins University School of Medicine for more than twenty years and have held joint appointments in the Departments of Medicine and Pediatrics.

I am board certified in Internal Medicine and am a fellow of the American College of Physicians, The American Academy of Pediatrics and a member of the American Society of Addiction Medicine.

I have particular expertise in medical education, clinical program development and community outreach and advocacy.

My husband, Matthew, is an otolaryngologist and we have four adult children.
