Dr Hobbs is the absolute best in every respect. I am fortunate that she is my Leukemia specialist. My family is also fortunate that she is. Considering all of the physicians I have seen in my lifetime for various (and sundry) maladies, she co-ranks number 1. The other specialist is also at Mass General. So, thank you Mass General.

This is a long-standing pt-doctor relationship, so I can repeat myself as needed: Dr. Hobbs is an exceptional physician--good listener, knowledgeable, and kind. She is also effective.

Outstanding physician!


April 2025

Dr. Hobbs was very knowledgeable, direct, clear in her communication, personable, and concerned about me as a whole person. My only complaint (a minor one) was that she had not read my chart quite as thoroughly as she might have in advance of our appointment.

Professional, caring, with empathy

She was very helpful, very professional. I had a virtual visit with her and I had never seen her before. I don't believe I will need to see her again, but I have nothing else to say.
