    Dr. Fang is excellent. I was hesitant to see "another GI" as I've been through many in the past several years for my rare case. He took my case seriously and recognized the knowledge and treatment gaps there are for me. He was easy to talk with and reassured me with a solid plan moving forward. I also appreciate his if it ain't broke don't fix it mentality.

    Dr Fang is very personable. We talked for a few minutes before we ever started talking about the issues at hand. He made me feel like we were on the same level.
