I can't comment on the options for radiosurgery. For various reasons, I chose translab surgery at MGH. I did have one meeting with Loeffler, and my husband and I were definitely impressed with him.
But, the point I wanted to make is this - I have a neighbor and friend who is one of the radiation physicists that works with Dr. Loeffler. He was wonderful about sending me information, articles, and talking to me when I was deciding between radiation and surgery, with some articles specific to the type of radiation used at MGH. If you want to send me a private message with your email address, I can forward to you what he sent me.
I have nothing but good things to say about everyone I met working at MGH. But my father (who's fighting leukemia) says the same about B&W, where he's being treated. LOL!
