Thanks Barb, I found that yesterday. My daughter-in-law's father is a retired dentist from Rochester. I think he suggested Roswell because of "connections". My feeling is that why not just go to #1 (Sloan-Kettering). Duke University has been trating her for about five years without success in halting the tumors. The last one is thought to be invasive and they now want to cut deeper. My wife and I are in the "fast lane" of learning.
