Seems to be an issue with a transistion of medical history from one system to another. They had my supplemental insurance with a company I have not used and a supplement in drugs that my wife takes but not me.

Dr Diaz always asks and listens to what is going on with you, examines and gives her professional opinion and suggested follow up or treatment. She may give you choices which makes you feel like you are part of the process.

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.

I have complete confidence in my doctor
- 5 out of 5 starsReviewed on 3/1/2026
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.
