    I often find doctors to be dismissive and impersonal and I often feel rushed and intimidated. Dr. Duh was wonderful. He has explains things in a very understandable way. He is warm and patient and has a sense of humor. It was clear his staff and residents/interns enjoy working with him. One of the best experiences with a doctor that I have ever had.

    Very clear explaining issues gave description from beginning to end in1st 2nd & 3rd analogy including risk factors for every aspect of proceedure(s). Explained knowledge of degree vs Diagnosis of 1% individual rarity of the condition.
    Jul 16, 2022
    Dr. Duh made it clear to me that he didn't have enough time to answer my questions. He said he had many other patients to see that day and that he was already going to run behind (even though I was the first patient of the day.) I am dealing with hyperparathyroidism which involves surgery to the throat. Surgeons who perform this operation do not all agree with the approach that should be used. It was very important to me to have confidence in my surgeon and his approach. Because Dr. Duh was rushed I was unable to gain confidence in him. I was disappointed.
    Jun 07, 2022
    Dr. Duh is an outstanding teacher of medical concepts required to understand my condition and treatment. He reduced anxiety I was experiencing about my condition. Thank you Dr. Duh.

    Dr. Duh was exceptional in the amount of time he gave to explanations and clearly answering my questions. I am extremely impressed not only with his medical expertise but also with his communications skills.
    Feb 19, 2022
    If there were an Excellent or Outstanding rating I would have given that. Dr. Duh was amazing. My husband joined me on the call and we both agreed that he was incredibly knowledgeable and extremely articulate. He had studied my records and was very familiar with the issues so that we could have an in-depth discussion including alternatives. At the end of our visit we felt very comfortable that we had been provided the best advice and care. We feel we can rely upon Dr. Duh's medical opinion and trust in his judgment as well as his surgical skill.
