He answered every question. He did not make me feel rushed. I honestly thought he was one of the kindest doctors I've ever met.

I can't speak more highly of my experience with MGH. And I'm very, very pleased that I was put into connection ?

    Dr. Micalizzi was patient, empathetic, and courteous.  He answered all the questions that my husband and I had about my long-term cancer treatment and the pros and cons of different options (tamoxifen vs. Lupron injections vs. aromatase inhibitors).  He described all potential side effects in detail and some mitigation strategies.  I appreciated that he took his time to go through my long medical history, as well as my detailed family history, which involves a large number of cancer cases.  Dr. Micalizzi also mentioned the Lifestyle Medicine program at MGH, as a potential source of long-term support, which piqued my interest.  His post-visit clinical notes were very detailed and provided an excellent summary of our discussion and the complete treatment plan that we agreed on during the 60-minute visit.  My husband and I did not feel rushed at any point during the appointment, which was a welcome change from other doctors who spend no more than 10 minutes of face-to-face time with a patient.   Thank you for a positive experience!
