  • Dr. Diaz is a very professional and qualified endrogronologist. She listens and cares about her patient's health. She encourages her patients to help themselves take care of themselves.
    My experience of every visit with De Diaz- Arjonilla! Has always been good one. Don't ever want to change my Endocrynologist.
    Dr. Diaz reviewed my lab results & assessed a sprained ankle I had told her about. She gave me direction & I was grateful. I ended up needing to get a referral for an Ortho consult.
    Medical assistant and Diaz-Arjonilla were exceptional. I'm grateful for the care.
    Good visit overall
