    I was so very pleased with seeing Dr. Duh. The exam, the time he spent with me explaining the problem, the various treatment options, his visuals, and going over the risk of the surgery made me feel very confident in going forward. I could not be more pleased with my experience given the potential treatments and outcomes of my problem.

    Dr Duh, is so knowledgeable. He is patient and caring. The wait to see him was well worth the wait. I like how he does his own tests and walked us through several options. Thank you Dr Duh. You are amazing!
