His, I don't know if he's an intern assistant maybe, [redacted], I believe his name is, is absolutely wonderful and made me really feel at ease. They're both great at listening.

  • as always..........wonderful !!!

    2025-10-14

  • Dr. Trinidad is terrific, I have total confidence in him and I would recommend him, without hesitation, to anyone. My biggest concern is that our MGH physicians, nurses and other clinical team members are overburdened with the number of patient visits and their complexity. It's not clear to me that patients understand this. And when they don't, they take it out on the clinical team. I'd like to see a more direct approach to conveying this information to patients. I know there are signs in clinic advising patients to "behave". I'd like to see a handout or patient signable electronic acknowledgment to that effect. Clinical team burnout is real and I'm concerned not enough is being done about it.
