My wife and I were both sleeved on May 15th by Dr. Fernando Garcia in Tijuana. We were at Mi Doctors hospital and because we both had the surgery, our cost was $4800 a piece. That includes hospital stay (which was the best care I've ever had in a hospital), surgery (did not have ANY complications to date), hotel stay for 3 nights (Marriot was very nice and had great service) and transportation (the driver, Samual Jr, was right on time and a great dude).
From what I have seen on this forum, everyone loves the doctor they chose. So what that tells me is that they are all good and are all qualified! So my advice is to choose one that you are most comfortable with, for whatever reason, and don't second guess your decision. I'm sure you will be in great hands wherever you go.
It's an easy surgery to recover from. I went back to work 6 days after and could have gone back 3 days after.
