    The doctor was caring, thorough and knowledgeable. He actually helped finding an answer to my problem!
    Several medical events have occurred over the last three months. Requires greater discussion.

    Dr Nguyen handled my transition for care from my Reno provider (we just moved here) very well - made copies of my records from GI Consultants for Reno NV - asked lots of questions, made several very helpful suggestions to overcome my persistent bloating and indigestion issues
    I love love Dr D Nguyenhe is saving my life! He is young and on the cutting edge of FDA trials which he helped me WITH. He's young and enthusiastic which is my zone towards my total healthiness.
    I had a great doctor and my recent visit had been wonderful.
