DR. BERGER UCSF- Any experiences?

Well, this is my first time posting on this board. My Husband was diagnosed with GBM IV about a week ago. We were told it was inoperable due to location. After much research and several opinions we decided to get on a plane and go to San Francisco to see DR. BERGER who said he will operate. It was a hard decision to make but we felt this is my husband's best chance of beating this thing. Has anyone else been in this position and opted for surgery? More importantly, does anyone else have experiences with DR. BERGER? Please help!!!! Thanks
