Dr. Chang performed a colonoscopy and endoscopy on me. He is a wonderful, kind, and compassionate doctor who spends alot of time with you and explains everything very thoroughly. I am not very fond of his office staff though. I too had problems scheduling an appt. with him.

I called to schedule an appointment and was told that I needed a referral. I stated that my insurance does not require me to have a referral. Then I was told every rudely that this is a specialty and specialties require referrals. I have been to many specialty doctors and never once have I needed a referral. The receptionist was very disrespectful and kept saying that all specialty doctors require referrals and that you can’t go to a specialty doctor without a referral. I will be going else
