    Very little eye contact. Spends a lot of time typing stuff. Rushes through actual exam. Doesn't tell me that visit is going to be more expensive. Even thought he always seems rushed to move on, he spends time in exam room.

    Very satisfied with all aspects of the treatment I'm receiving from Dr. Chang. My only issue is sometimes he speaks to me in a soft tone with his head not facing me. I have a hearing loss and I often have to ask him to repeat what he said.
