    I'm so thankful that I found Dr Diaz. The receptionists are great. Friendly and kind and efficient. I very rarely have to wait to get into the exam room. The MA's were thorough and understanding. Dr. Diaz is very warm and listens to me. She actually thinks about what things could be. And she takes action. I appreciate her and will continue to see her for as long as I need a Pcp.

    Everyone was very nice. However, the computer froze so that it took around 15 minutes to get checked in. This meant a delay in actually getting taken back on time. If a computer is frozen, the staff taking patients back to the rooms should be informed that the patient is there but that the computer system is currently not working.
