I live in the Seattle area, and wanted some clarification. The "Seattle area" is really big! lol Are you moving to Seattle proper, or was that the big city near where you are moving?
I wouldn't suggest using any of the doctors at Group Health, I have mine trained (after a year), but for the most part, they just go through the motions and seem to get annoyed if your body gives complications. Virginia Mason and Swedish clinics both have great doctors, from what I hear.
I hope that you won't, but if you need a surgeon, I would definitely suggest mine. His name is Martin Herman. He is a GI surgery specialist. Last year when I was having trust issues with my doctors, he was the one that I trusted. He is at Overlake Hospital for his surgeries, I don't know if he is at any other hospitals, not sure if they can go to multiple hospitals. His office is right near Overlake hospital.
Let me know if you want to get together to talk when you get to the area, I like meeting new friends!
