Has anyone or is anyone getting RNY with Dr. Mondragon?

Hi. I am planing my revison surgery from LAPband to RNY with Dr. Alejandro Mondragon. Anyone else have him? 

No...I don't know of him.   I've been researching weight loss surgery and  wanted to ask you a question:  WHY are you getting a revision?  I am wondering because I can't decide between the RNY and the lap-band.  Do you have specific pros and cons of each?
