Totally satisfied with my visit with Dr. Clancy.

I was happy he was flexible to accept a request to change to a virtual appointment, rather than having to drive into Boston for a short meeting where the doctor was just discussing the results of an MRI. That saved me almost 3 hours

In the 2+ years since my major abdominal surgery occurred, Dr. Clancy has been readily available to see me or respond to any questions I might have about my health. In this particular visit, as is always the case, Dr. Clancy took the time necessary to explain the results of a recent MRI and to assure me that all is well. He is always patient, empathetic, and willing to take the time necessary to ensure my confidence in my own health.

Dr. Clancy was extremely interested in my health and he went overboard to get back to me to coordinate the one test that we did have. He actually called me at home three different times to bring me up to date as to what was going on. He's an extremely caring and qualified individual and you were really lucky to have him. He's great.

He took the time and looked and told me that my cysts were in the branches and not the main duct which was my question on the reading of the MRI. [redacted] He relaxed me.

Dr Clancy is one of the most caring, attentive, bright physicians I have ever seen. He is in a class by himself. He goes out of his way to make sure all the lab test, x-rays, visits etc. are grouped into the fewest possible visits since I traveled so far to see him.
