  • This was my first visit with Dr Abelman. [redacted] The appointment had to be changed to virtual that morning, so I didn't meet my potential new oncologist in person, but the appointment went well regardless, and we will have a follow up visit shortly to meet in person and for me to experience the MGB cancer care center. Dr. Abelman was professional, personable, knowledgeable and seemed very caring so I'm hoping she is a good fit for my care. I would like to stay with MGB [redacted].

Dr. Abelman fit me in on just a couple of days notice to talk about my proposal to change medications, listened carefully to what I had to say, and had a thorough knowledge of what needed to be considered in making the switch.

  • And that was Dr. Rachel Abelman. Just one time for a consultation along with a surgeon and radiologist. She was extremely nice, listened to everything I had to say, extremely competent. She gave me great advice, medical advice. It was spot on. I'm not sure if I need to see her in the future, depending upon what pathology she's back with. after my surgery, but I would love, if I need an oncologist, she is the person I would want. And she's very capable and I feel really comfortable having her as my doctor.
