Yes, I spoke to them prior to making my decision and actually read some info on them and it scared me. The hole they made is very small and if you have a bleeding problem they can not open you up fast enough to fix it. If you had a small tumor I'd consider it but not with a large one. I know if you do a serach on the net of them you should see some articles in regards to their services. Let's face it, if they are going into your skull they are being invasive..what difference does it make if the hole they gone in through is 1 inch in diameter or twice that size? I wanted them to make a big enough hole so they could see what they were doing and had plenty of room to work LOL
I had retro due to my size and location (2.8cm and pressing on the brain stem).
I know matti is from CA she might know some good doctors for treatment.
