I had a two level spinal fusion on L4L5 and L5S1 in September of 2010. While I am still on the mend I am glad I selected Dr. Cammisa out of the five doctors I saw elsewhere. I liked his procedure and the way he explained it. I know he is very busy, but he had time to explain everything. Questions that I had later were always returned via email in a timely manner. Also, I was very grateful for the superb nursing care at HSS. For my first time staying at a hospital for a week I was put at ease by the nurses. Both the day nurses and night nurses were wonderful to me. When I came home and had questions about follow up care, Yvonne Rosario always answered my questions and reassured me when I needed reassuring. And the physician assistants Theresa and Vanessa are great, too.
