I don't have any feedback on California, but there is often mention of Kaiser, so I am sure someone will speak up.
My surgery was done by Kawachi. He has done over 3,000 robotic prsectomys. His bed side manner is nit great as i develpoed a blockage in my bladder neck and he kept telling me everything was fine. It did resolve itself after about 2 months. City of Hope is a very well ragarded hospital for it cancer care. All and all I would say you will be in good hands.
go where you have the confidence. I'm in Nor Cal I don't know any of the Kaiser Doctors you mentioned. Kaiser is different insurance. My co-pay was $15. I guess that's the difference. My Doctor had only done hundreds. What ever you chose will be the right thing to do for you.
Best of luck and sorry your here, but welcome just the same.
