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 BA from Texas A&M University. I am a graduate of the University of Texas Medical Branch School of Medicine and completed my combined internal medicine and pediatrics residency at the University of Texas Medical Branch. I also have a masters degree in preventive medicine from the University of Texas Health Science Center at Houston and an MBA in health care management from Johns Hopkins University. I joined the faculty at Johns Hopkins University School of Medicine in 2004 and in my more than 20-year career there, I maintained a busy adult private primary care practice and I became professor of clinical medicine. In my career, I have taught scores of medical students, residents and fellows how to become an exceptional physician. I maintain my part time faculty status at Johns Hopkins.
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 expertise in preventive medicine, lifestyle medicine, chronic disease management, pain management, women’s health, obesity and endocrine, cardiac and pulmonary disorders. I treat all ages; my patients range from adolescence to geriatrics.
My husband, Matthew, is an otolaryngologist and we have four adult children.
