Dr. Chang was very patient, kind and knowledgeable. He gave me a referral to a doctor he feels could help me and my health situation and explained why.

I was very disappointed with Dr. Chang, had no regard for my questions or concerns, was incredibly dismissive, and frankly made me feel small for having a concern I'd even bring up.
