I was just at Dr. Ortiz's office on Monday and had absolutely no problems crossing the border. I too was very nervous about going into Mexico but had OCC pick me up and drop me off on the US side... it was nothing like I expected! DO IT!
I am going to Dr. Ortiz in TJ at the obesity control center on 7-6-09. His staff is wonderful and the price is very reasonable. They p/u and drop pff on the US side so you never have to be alone. He has done over 7000 lapbands and trains other Dr.s to do the lapband.
