    MGH has always been the gold standard of hospitals for me. The physicians and staff members are knowledgeable and kind and frequently check in to ensure my questions are answered. I feel so privileged to be able to have Dr. Oh as my Radiation Oncologist and am grateful to everyone on the team.

    Luckily, I only have to see Dr. Oh every 3 years. As I mentioned to him at my appointment, I was pleasantly surprised at the efficiency and professionalism of the staff from setting up the appointment to my appointment with Dr. Oh.

    Dr. Oh spent a good deal of time with us to ensure he began to build a relationship with me and my husband, to thoroughly explain my situation and next steps, and to provide answers to our questions. We were impressed.

    Dr Oh has a fantastic bed side manner. He was calm, informative and kind, as was the resident Dr [redacted]. They both were very patient and very kind. We had a lot of questions and it was the end of the day, we never felt rushed. Dr Oh had even gone ahead and looked into facilitating treatment closer to my home, which I greatly appreciated. I was so impressed with how my different teams of physicians communicated about before my visits. It really takes a lot of the stress of being sick out of the equation when you have so many people working together to make your life easier. [redacted]
