in Deer Park, TX |
Tried to make a first appointment The lady said for me to see the doctor I needed my medical record and a few other things just to make a appointment. I told her of all my years going to a doctor I have never b een told such a thing. I did not get a appointment. I hope he goes broke. If he is that picky in who his patients. Of course it may have been my Medicare insurance. Either way I found his requirements and the staff to very unpleasant. I will go to him if he wanted me to.

It was my first time seeing Chang after my amazing endocrinologist retired, and not only did it take forever to see him, but I'm not even sure that they know of the disease I have. He started out the consultation with How can I help you?- even though he had labs and everything to know what was going on. This guy is awful and am now doctor shopping, again.

I called to make an appointment. I was denied because this doctor will only see you if you are referred. I was told that it was his personal choice to do business that way, regardless of the insurance that the patient carries. I have insurance and he is in my network. It did not matter. So now I have to pay for an office visit to another doctor and take additional time off from work, just to get a referral. Not cool.
in League City, TX |
I was referred to Dr. Chang by my OBGYN for gestational diabetes management. I find Dr. Chang really easy to talk to. He has answered all of my questions, referred me out to a diabetic class to learn as much as I could, and has stayed up with my pregnancy. I've never waited more than 15 minutes to be seen. I have nothing but positive experiences with him and would definitely recommend him.
