I am being banded on 7/26 by Dr. Lopez Corvala. There are alot of mixed reviews about him and this board which did really start to worry me so I start looking around more about his expertise. I have contacted several people that have had the banding down by him and they all have wonderful things to say about the whole experience. You can call the hospital and as about the doctor do a search on the internet under his name. I did this and I was amazed on how many sites came up with all the expertise that he has. Just do your homework and you should be fine. I do understand that some people may have had a bad experience with the doctor but I think it really depends on your health going into it, how you follow what you are told to do. But honestly if you look around at any doctor anywhere in the world I am sure you will find at least 1 unhappy person with their doctor.
Good luck in your search.
