I hate going there. I am stuck because he is the better of the 3 family doctors my insurance will cover. The waiting room is like a barn full of cattle and every time I go there I catch something in the waiting room. I have anxiety attacks the entire drive there. Dr Diaz is not much of a listener or talker. The PA's are pretty good. The nurses can be jerks. No one there can take blood and butchered my arms. I go to the lab now. I'm high risk heart disease, no one knew how to get evaluated. Duh!

I waited well over an hour and was forced to pay before seeing the anyone. The male who came in the room didn't even bother to introduce himself and was going to leave the room without telling me anything.

After three visits finally met with Dr. Diaz and he was very rude. Spoke to him about medications prescribed while at hospital and he got upset. He yelled and said he didn't care about what I was telling him. Apparently he didn't care about his patients medical history. I wouldn't recommend him to anyone. He spoke down to me and it wasn't appreciated.
