    Dr. [redacted] and Dr Defilipp were a breath of fresh air. They listened deeply, answered all of my questions, shared a wide breath of expertise and knowledge, and freely shared what was known and unknown in the science of AML today. It was a difficult discussion, which they handled with care and compassion. to my surprise and delight, they were in no rush to conclude the conversation. It went on much longer than I anticipated. They had time for me, and they never rushed me. In the end, they even asked if all my questions were answered, and if there was anything else I needed before we concluded our zoom visit. Above and beyond that, Dr. Defilipp asked me to get in touch with him if any other questions came up in the future. I am deeply in debt to these two physicians, and my second opinion with them continues to give me food for thought, as I contemplate the future path of my treatment. MGH is lucky to have physicians like them.

    From the moment that I've met Dr. Defilipp to this current minute, he has been outstanding in caring for me, my family, and anyone else involved with my diagnosis. He is educated, he is timely with his education, and he provides a stress-free, trustworthy care. I will never not go to him for my care and I highly recommend him to any patient, any person that I know who will be needing oncology care.
