Patient Comments (8)
I had an untreated thyroid storm that landed me in the ER twice. I had no medication and I am the mother of a baby. No one would see me (St Louis: 6 month wait, or pay $2,000 to get on schedule; Dr Sfeir wouldn't see me because I lived "outside service area" - nevermind the oath to help people). I am thankful my ER Dr referred me to Dr Chang. He and his staff are caring and understanding. Someone finally listened, figured out what was wrong with me and is helping me. It quite possibly saved me.

I have seen Dr Chang a few times now and he was awesome. He explained everything thoroughly and answered all my questions. He was kind and his nurses are wonderful as well.

I've been seeing Dr Chang for a few years now and he's amazing. He is not a talker, but he does answer questions and is open to suggestions.

I went to see Dr. Chang a couple of times, each time leaving frustrated, but returned to give the office another chance. The nurse sprayed my blood all over the floor by not following the correct steps for a blood draw. Part of me thinks she could have been drunk. Dr. Chang has poor eye contact, no bed side manner, and walked out of the room each visit without answering my questions, or even saying goodbye. He doesn't seem happy with his work, which is unfortunate.

This was my first visit, and I didn't have to wait very long to see him. He was friendly, courteous and very knowledgeable about my condition. He shared a lot of information with me and took time to answer my and my husband's questions. Definitely put my mind at ease.

I was very pleased with his medical insightfulness. Within the first visit i was impressed with his throughness. During the 2nd and 3rd appointments I realized his personal thoughtfulness. I highly recommend him.

Spent time with me and was very helpful. He was very concerned since I have been a diabetic for almost 2 decades and still have uncontrollable numbers even with my insulin pump. He gave me a lot of insight and came up with a program for me. So far have seen lower and amazing numbers and beginning to feel much better. Have been to many for my diabetes but this is the one who is willing to really help me.
Dr. Chang doesn't take the time to listen to his patients. He only focuses on weight and not on the source of the problem. He even told me that he was surprised I did so well, he didn't expect me to be successful.
