    Dr. Ron Flanagan did an excellent job. I was very happy to meet him and I think he's a very, very fine doctor. So glad that I have him as my gastroenterologist.

    Dr. Flanagan was very thorough and had familiarized himself with my very complicated medical history. He listened to my concerns and prescribed a plan for treatment and follow up. I would recall him to anyone.

    Before seeing this doc, I saw a different GI doctor closer to home. The difference between them was extraordinary. I stopped seeing the first guy, and stayed with Dr. Flannagan. He is knowledgable, articulate, and patient. He explained his thinking to me throughhout some two years of treatment. He regarded me as an equal human being with a medical problem that he wanted to help resolve. And he did. I enjoyed working with him. He is steady and warm. The first doctor I saw closer to home was full of himself, explained nothing, gave me a prescription and told me to come back in a year. I am especially glad to have found Dr. Flannagan. He's enjoyable to work with. It's easy to speak with him. And he finally figured out what would solve my problem. For the first time in four years, I am living without suddenly throwing up. Five stars for Ryan Flannagan.

    Dr Flanagan took the time to really listen to my recent symptoms and concerns. He explained what he thought might be happening and the appropriate testing that would be required to confirm a diagnosis. I'm so very pleased to have him as my specialist. I feel I'm in very capable hands. I would definitely recommend him to family and friends searching for a GI specialist

    Not sure if the person doing pre-MD functions, e.g., blood pressure, medication verification, was a nurse of perhaps a medical assistant, but she was terrific!! Was very pleased with Dr. Flanagan--I am a "frequent flyer" in the MGB system and found him--on this my first visit with him--to be superb. Thank you.
