    Yes, Dr. Barnett always listens to me. He always explains things thoroughly. That's why I have been with him for years and hope to be with him for many more years. The support staff is always good to me. I have no qualms at this time.

    Dr. Barnett is one of the best doctors in Boston. Other doctors told me that when I was in the hospital. I'm not surprised. He is amazing. Other members of my family and friends want to be associated with Mass General Brigham because they hear me talk about how outstanding the doctors are and how caring. He is just amazing. He is such a great doctor. I must have done something good to be able to have him as my doctor. Thank you.

    The experience was actually comforting and given with care. All my questions were answered all my information was clearly explained and at no time did I even have to have a follow up question. I felt like I had been treated special and the experience of everything but especially the Dr was a wonderful experience. I wish all could be like that thank you.

    I feel that my provider, Dr. Barnett, has my concerns and my health very much in his focus. I feel he is very smart, very knowledgeable, and he truly is concerned about me at times when I need him. So I feel like that's very important. That's it.
