2026-01-01

[redacted] He would not let me speak and kept saying he was a doctor for over 45 years, and he knew everything about me. I did not get a chance to ask my questions. He told me, as he did in past, about the medications HE takes after he eats. At this visit he also told me everyone in Hingham takes lots of medications. What? I have no ties to Hingham whatsoever. Totally inappropriate comment. Quite disappointed with the visit. He does not use the computer to enter visit notes or order labs, rather handed me approx. 20 pages of my records that I already have and can see on my portal. When I checked out, my labs that he wanted done were not entered as he said they would be. Quite a disappointing visit.
