    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.

    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.

    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.

    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.

    Dr. Duh was a wonderful surgeon. He explained every detail to me in a friendly manner as I was very apprehensive about the surgery. He was waiting for me when I arrived at preoperative room and he came to see me when I was waiting to be discharged. Just a wonderful man!!!
