Dr Chang is extremely thorough, caring and really listens to a patient's concerns. I never feel rushed by him and he always takes the time to answer all my questions. I would, and have, recommend him to anyone. The fact that I make 140 mile round trip to see him speaks volumes!

Dr. Chang is a very professional, caring and competent physician once you get in to see him. I have a hiatal hernia that occasionally causes me extreme discomfort. During an episode some months ago his office was unable to schedule an appointment for me until approximately 2 months in the future. I realize that my condition probably isn't life threatening but as an existing patient I hoped to be seen sooner than 2 months. That is too long to wait when you are in pain.
