Dr Guseh was smart, knowledgable, humble, concerned, caring, attentive and clear with his communication. He spent the necessary time to make sure we understood what was going on. This is the way doctors used to be. I would recommend him and MGH.

He is a very skilled and compassionate doctor who gave me the confidence that he would work hard to figure out what is happening to me physically that other doctors have not been able to figure out.

My provider was absolutely top notch. The expectations of time to provide care is unrealistic and not being able to run "on time" I now consider a reflection of a committed practitioner.

Dr. Guseh went well beyond my expectations. I was extremely impressed with the questions that he and the other clinicians asked, the in-depth history that they took, the feedback and interactions I had with him/them, and the fact that they spoke to me as if I was a member of the team and not just a patient. I absolutely loved Dr. Guseh! I feel so incredibly fortunate that I got an appointment with him.
