Dr. Mann was my oncologist at Florida Cancer and I was devastated when I heard he was moving. As luck would have it my husband was able to locate him. There are not enough words to express my feelings accurately about this doctor. From my very first appointment, he has shown nothing but caring, empathy and a true sense of understanding. He spends time explaining your course of treatment and why. Answers any and all questions and makes you feel like he has all the time in the world to spend with you. Feel truly blessed to have this wonderful doctor treating me and would recommend him to anyone forced to deal with cancer!
