I graduated from Harvard College (magna cum laude) and Cornell Medical (now known as Weill Cornell). I did my internship and residency training in internal medicine at Johns Hopkins Hospital. My fellowships in pulmonary and critical care medicine were at the combined program with Harvard Medical, Brigham and Women's, and Boston Beth Israel Hospitals; I did a subsequent research fellowship in Respiratory Biology at the Harvard School of Public Health. I am board certified in internal medicine, pulmonary medicine, and critical care medicine.

I have received a number of awards: Harvard Ames Award; outstanding medical resident, Johns Hopkins Hospital Medical Service; many teaching awards at George Washington Univ. School of Medicine; and the Preceptor of the Year Award from the D.C. Chapter of the American College of Physicians. More recently, I have received the 2015 Humanitarian Award from Suburban Hospital for my work with G.W. Haiti medical mission, and Mercy Health Clinic, where I volunteer twice monthly and serve on the Mercy Board of Directors. I am also the 2016 Hopkins Armstrong Quality Awardee for my work with the Suburban Hospital Provider Quality Committee, which I chair.

I am the Immediate Past President for the D.C. Thoracic Society.

I am a Clinical Professor of Medicine at George Washington University School of Medicine, but do not go to George Washington University Hospital.

I seek to provide the care that I would want to receive or have delivered to a family member. This includes excellent, compassionate, state-of-the-art care.

I help patients with breathing or lung problems. I often see patients who have chronic cough, shortness of breath, wheezing, asthma, Chronic Obstructive Pulmonary Disease (COPD), pulmonary fibrosis, pulmonary nodules, sarcoidosis, pulmonary embolism and pulmonary hypertension. I often see and manage patient with collagen vascular or rheumatologic problems when they affect or are likely to affect lungs; these patients are often co-managed with rheumatology consultants. I also see and manage patients who have sleep apnea. 

I have been doing flexible bronchoscopies since 1983, and have taught this procedure both locally and at Harvard/Brigham and Women's Hospital. Most of my bronchoscopies are performed at Suburban Hospital in Bethesda MD. I also have a pulmonary function laboratory in my office, and interpret those tests.
