John J. O’Connor, DO

“I have been practicing Gastroenterology in the Montgomery County area for the past 15 years. I’ve learned very quickly that in order to provide the best care and service possible to my patients, I needed an equally committed team of supporters around me. At the Center for GI Health & The Colonoscopy Center, we, the doctors, physician assistants, nurses and support staff, have all come together with one goal in mind: To provide the most compassionate and comprehensive care to the patients in our community with the highest level of professionalism at all times.”
