Not sure if you are still looking for a Dr. in Houston. I had my AN surgery in January 2005. It was done by Dr. Vrabec (ENT) and Dr. Trask (Neurosurgeon) of Baylor College at Methodist Hospital. The surgery was a huge success (see my earlier posts for more details). For that, I am very grateful.
Before the surgery, I spent quite some time in searching for options as well as doctors for the treatments. Dr. Joseph Chang (ENT) and Dr. Vollmer (Neurosurgeon) was the other team that I was seriously considering at the last minutes. Both were at Herman Hospital but holding teaching positions in UT Medical. Dr. Change is a Harvard graduate. If I remember right, he was the Director of some department in UT Medical and Dr. Vollmer was the Chairman of Neurosurgeon. I made office visits to both of them. They both appeared to be very competent and very patiently explained all the questions I had. I agree with Larry, Dr. ChangÃ¢â‚¬â„¢s English is excellent. Most likely, he grew up and received most of his education in United State. Being a Chinese myself, I did not pick up any Chinese accent from him. In fact, I am not sure if he speaks Chinese at all.
Although at the end, I decided to go with Dr. Vrabec and Dr. Task for my surgery (and they did an outstanding job on me), I have to say Dr. Chang and Dr. Vollmer also left me an excellent impression.
Any way, this is just some information for you. Should you have further question I can be of help, do not hesitate to ask. God bless you.
