    Dr. Belz really listened to me and is exploring reasons for what might be causing my lung issues. This was reassuring because I didn't think it was possible to get more answers about why I have these issues. He also gave me encouraging information about what he thinks is going on right now, it was a huge relief.

    He was running behind. I recently read a review about my condition. I had several questions that I do not usually have because I read the review. Dr. Belz took the time to answer all of my questions even though he was running late. I felt a bit bad about taking his time when I don't usually have a lot of questions. I appreciate his patience with me.
