I have been researching plastic surgery in TJ, too. I called for the office for reccommendations but I still feel like I need personal experiences from actual patients. Kind of like here - where you can talk to patients.
I found a support group for patients of plastic surgeons in Mexico and was very happy to "meet" other patients of some of the docs the office reccommends. There are lots of before/after pics of post WLS patients there, too.
Anyway, the site address is www.plasticsurgeryjourneys.com It is not affiliated with any specific doctor.
Good Luck with your research!
