    Excellent care provider.

    Care provider listened to me and we discussed my present condition and what I was doing as far as taking medications but I still do not totally understand my issue/condition/illness. What's the cause? Is there more I can do? She can do or recommend? I'll send her a message so that she can address my questions and concerns.

    My current medical condition has been very frustrating and impacted my quality of life. Dr El-Nachef really listened to my concerns heard how impactful it was and created a two-pronged plan including diagnostics and therapeutics. I really appreciated the ability to "start work" on it right away and the sense that there was a good plan ahead.
