I know that your post is kind of old, but I noticed you only got one suggestion -
The Sherman Denison area is really nice - I really hope that you enjoy it!!!
It is only about an hour south to Dallas - there are a number of Doctors that have their patients fill at the Surgery Center of Richardson. Dr. Powell, Benavides, Allen, Bryce and many more. I have heard good things about all of them. The website for the entire group is
www.lapbandsolutions.com
They seem to have been doing a number of bandings and I know that Dr. Benavides does the aftercare for a number of patients banded in Mexico. That might be a challenge with some of the other Dr.'s - I am not sure.
I had my band placed at Surgery Center of Richardson and the people are very nice and it is a nice facility.
Good luck and welcome to Texas!!
