  • I used the Portal to ask Dr. Diaz about renewing my prescriptions & about a test, & she replied quickly. I appreciated that very much. Same with my primary, Dr. F. Martinez.
    Everything is good except waiting to meet the doctor in waiting room that usually takes half an hour after appointment time.!!
    I feel comfortable with Dr. Diaz and think she is a very good doctor.
