    I recently had an infection in both of my eyes. He followed up with me every week, working with me, until it was healed."
    Amy Schall

    The experience of his professionalism is consistent, truthful & helpful. You owe it to yourself to get the best Doctor for your vision. Go see Dr. James Phung and SEE
    What you've been missing out on.

His prices are great and he is a true professional and explains things very well and answers all questions in a way that you can understand. I would recommend him to anyone."
