About Us

In the Washington Metropolitan area, you have many options when choosing a gastroenterologist, but my practice is different!  Here are some of the ways:

  • Phones are answered by a real person who will actually be able to help you
  • All visits will be with a board certified gastroenterologist.
  • You will be seen by the same person for your consultation, procedures, and follow up visits.
  • Procedures are performed at both an outpatient surgical center and Medstar Montgomery, depending on your medical needs, insurance plan, and preferences.

Marc L. Kozam, MD

I have been in private practice in Olney, Maryland since 1996, live with my family in nearby Sandy Spring, and am proud to have served over 12,000 patients from my community.

I received my undergraduate degree in Biochemical Sciences at Harvard University, then did research at Massachusetts General Hospital before entering the University of Alabama School of Medicine.  I completed my internship and residency in internal medicine at the University of Maryland, then completed my fellowship in gastroenterology at Georgetown University Hospital.

I have been listed in Washingtonian’s Best Doctors and was named as Medstar Montgomery’s Physician of the Year.
