I was fortunate in having Dr. Vincent Massullo as my physician while being treated for prostate cancer. I found him to be extremely caring, knowledgeable and professional. His manner is direct and reassuring. His communication skills are such that he delivers his opinion along with the facts in such a positive upbeat manner putting this patient at ease. In a more casual moment he has a gentle sense of humor. I would recommend Dr. Massullo who is in need of cancer related radiation.
