This was my second time with Dr. Koff (the first time was an in-person visit to his medical practice for preparation before the medical procedure). Dr. Koff is professional, kind, and patient, and takes his time to answer your questions. His staff at Capital Digestive Center in Chevy Chase was extremely nice.
