My visit was stressful in as much as I was late due to the MBTA and their inability to follow a schedule. The doctor, receptionist and all the staff I interacted with were beyond expectations and their kindness and understanding put me at ease. I can't praise them enough. So amazing they made my lateness seem like a minor inconvenience and were beyond accommodating.

Dr. Micalizzi is the single most caring provider I've ever had. It feels almost unbelievable for someone so intelligent and skilled to also be so empathetic and kind. He listens when you speak, he answers thoughtfully and with real care in those answers.

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!
