  • I worked diligently to bring my A1C down was successful and the Dr never mentioned it@
    Love working with Dr. Diaz. Very collaborative and intelligent with my Type 1 Diabetes needs
    Dr apologized for wait time as she was on call to the hospital & got a bit behind. Wait was not bad.
    To: the doctor -Thank you for your time to fill out the heathcare form that I have asked. Appreciate a lot.
    Dr Diaz is very thorogh and takes time to exolain results of tests.
