I had a very good experience at Harford Endoscopy for a colonoscopy . I will be going here in the future again ! The nursing staff were very caring and made sure I was comfortable at all times. The anesthesiologist made me feel very much at ease . I cannot say enough great things about Dr. Nasser , the gastroenterologist. He is the nicest person . He’s very caring , and truly cares about your comfort and reassures you about being well taken care of . I hope to always have Dr. Nasser for my GI appointments . Love him and his staff❤️
