Dr. Diaz is not friendly at all. She goes through a list of new meds and when I said I took one and didn't like it, without acknowledging I spoke she finishes her list. She also got irritated I didn't get my cholesterol checked when she's the one who sent it to the lab. She claims it was my fault...more
