I was with Kaiser for many years (until one year ago). You have to know how to get around in their system, get a good primary care doctor, etc. I have no complaints except with orthopedics. The ortho docs may be good, but if you can never get an appointment with one of them, then it’s irrelevant. I had an email relationship with my primary care doctor. He responded promptly to me, sometimes even on weekends and holidays. Kaiser is really good on preventative care. If I didn’t now have orthopedic problems, I’d still be at Kaiser (San Diego).
