Dr Nicholas Hannon is an outstanding physician. I am so grateful to have gotten in to see him so quickly. He took the time to listen to me and to educate me. He relieved me by ordering appropriate tests and gave me suggestions on how to handle the symptoms if I experienced another pancreatic attack and things I could change to give me the best chance to avoid another attack. My daughter and I enjoyed our visit with him.
