I had Kaiser years ago and was treated badly by a physician's assistant who kept cutting me off mid sentence. He was the most arrogant and patronizing person I'd ever encountered, and I was brought to tears by how angry I was! I chose to switch to a PPO but had to go back to save money. But I just had a run in with a phone appointment operator who talked down to me and gave me a guilt trip for taking too long to return their call so they had to "close out" the request and make a new one and she really seemed put out by that, even after I explained that I'm an overwhelmed teacher at the end of my school year. I really regret going back to them and plan to find other insurance as soon as I can. Their customer service SUCKS!
