  • Dr. Medford is exceptional. She is kind, compassionate, brilliant, really listens to my concerns, takes the time to answer all my questions, and is always willing to go that extra mile to get an answer or bounce ideas off others. I feel very fortunate to have been randomly assigned to her almost 3 years ago.

  • She was on maternity leave when she got my file on a test result that was concerning. She immediately made an appointment with me to discuss it unsolicited. I was just waiting for her to get back from maternity leave. I really appreciated her reaching out when she didn't have to do that.

  • Dr. Medford has been my doctor for the past couple years, my oncology doctor, and she's been fabulous. She is always following up with me, explains things, is really thoughtful. I feel like she really takes my feelings and my lifestyle into consideration, and she's also willing to advocate for me when I need someone to advocate. So I would say she's fantastic, and she's a real value, a treasure to the Mass General Hospital oncology.

  • I really didn't see nurses, so that's why I gave them threes. I only had one bring me into a room, and I think he was a nurse. Maybe a tech, I'm not sure. I saw a team of doctors when I was there, and all of them were wonderful. I know this is specifically asking about my oncologist, but my experience overall was positive and communication flowed easily both ways.

  • Dr. Medford started my appointment by sharing that this is a good news visit which was very thoughtful. She remained incredibly positive and thoughtful throughout the appointment. She made sure to get my husband name correct and bring him into the conversation. And I greatly appreciated that even though she is not actively treating me, I can consider her my Oncologist and reach out with any questions in the future.

  • Dr. Medford was extremely positive and helpful. It was a lot of information to absorb, and it would have been helpful to spend time right after with her RN and the instructions about chemo treatment. Just having it on gateway and a generic printout isn't sufficient. Everyone was very helpful and professional, Waiting for teaching session a month later and scheduling and surgeries is a lot
