    Took time to explain everything.
    She didn't prescribe any medication. I would recommend someone who had kidney problems.
    *Dr. Chen takes the time to talk about your health.
    *Dr. Chen is far far more professional and treats me much better than the Mayo Clinic where I was a patient for 2 years or so. This woman saved my life 3 times from inches of death by ex-wife poisoning me.
    Never had a bad exper. in over ten + years w/*Dr. Chen.
