J Mark Sloan, MD

"Amazing Dr who listens to your needs. I was so happy with his care in Boston when I had cancer. Highly recommend"

"Dr. Sloan has shown me nothing but compassion in all my visits with him. He has answered my questions and even answered my text early on a Sunday morning when I developed mouth sores from the chemo. He is responsive, professional and takes the time to really explain things to me."

"Extremely unsympathetic, a family member of mine just recently got diagnosed with cancer and she had to go back to Boston Medical a few times and he seemed almost as if there was other problems and stuff he had to deal with than dealing with the problems with my family member, he also dismissed any questions we had to ask him and tried to justify himself. I definitely do not recommend this doctor unless you like to treated terribly and poorly."

"I had a horrific experience visiting this doctor at his hematology practice at Boston Medical Center he was extremely dismissive and condescending towards me and I would even say he was racist he dismissed all of my concerns and made it seem like I was inconveniencing him and wasting his time he went even as far as to say he had better things to do than to answer my questions and address my concerns he was also accompanied by an assistant who basically was following his lead he is by far the worst doctor I’ve ever come across and should not be allowed to practice medicine."
