I had gastric bypass in Puerto Vallarta On Feb 12, 2012. I weighed 256 and I am still 100 lbs down. I was down to 126 at one time, but have gained over the years. Dr Joya did my surgery. After I had it done. If I could have picked any dr in the US I still would have chosen Dr Joya. I think his name is Dr. Armando Joya... I would highly recommend him.. I went back about 2-3 years later and had a face lift. I don't remember that Dr's name but I went back to see Dr Joya. He was just as nice and came out to see and visit me. So glad that is who I went to. I have a friend who had it done here in MO. she gained most of her weight back within 3 years. Im happy with mine.
