I've been treated well whenever I've gone to the doctor. I've been treated well when I go to the lab or for my appointments, and the doctor treats me very well. Also, if someone asks me about my health insurance, what I think of it, I tell them, well, I like my health insurance, and if they want, they can go ahead and make an appointment and see how it feels. And that's how it's been. I'm very happy with my doctor, Dr. Cassanego.

I like Dr. Cassanego. He's limited by the health care system. It takes forever to get an authorization. He, it also, the only reason I didn't give a 10 and some things, he's got to get back to me on a colorectal doctor. So that was one of the things I asked for is a good colorectal doctor. So he's supposed to get back to me on that. It's also not that easy to get an appointment. It's not his fault. It's the systems. But I was glad I got one within the two weeks I requested. But that's the issue. Again, the big problem with UMANA and Kviva is the authorization process is not good. It used to be better. Thank you. But I do like Dr. Cassanego.
