Just had my band inserted on Tuesday with Dr. Rumbaut. Back home yesterday and getting used to my fluids. I cannot advise you more strongly to go with Rumbaut! The whole experience was very positive. He is definitely the "rock star" of the lap-band world and even the cab drivers in Monterrey know who he is! He's a little cocky of course (all good surgeons are) but that's because he's done about 3500 Lapbands and is THE pro. He's got a state of the art office and the hospital room was absolutely gorgoues (private room, hardwood floors, clean and pristine, marble bathroom, etc.) My mom came with me and was very nervous about the whole Mexico thing but after the first day, she was 100% convinced that Rumbaut was the right decision. Monterrey is a very rich city. Almost everyone we saw were businessmen (population is much more "Spanish-Mexican" than "Indian Mexican). BUt what I really loved the most is the personal care. Rumbaut has several younger doctors who work for him and they're constantly checking on you, coming by the hotel to personally deliver meds, etc. If it was the U.S., you'd have to go to THEM and not the other way around. My ONLY complaint was ONE nurse (out of many) who had very poor English skills. Everyone else spoke fluent english. I could not recommend Rumbaut anymore. I'm a Harvard educated lawyer from NYC and definitely did my research on him professionally. He is very compentent and I never once doubted that I was in good hands!
Good luck!
