The staff is very friendly. They were very nice and for the second time since I've seen Dr. Mercado she seemed rushed, not that interested in issues that I was concerned about and she used to be so much so much more interested in what was going on with her patients. It's just though she doesn't have time and just rushes through so I'm very disappointed in her.
