Has anyone banded with Dr. Julio Teixiera in NYC?

I have attended the first office consultation, unfortunately he was in surgery, I have the second visit on 6/23 and I only need two more visits with the nutritionist. Some of the recommendations that were given to me was to try to lose some weighed 254.9 lbs at the time of the visit on 5/29. I am currently at 251. Are they looking to see if I can lose the weight on my own. If anyone has had surgery with him what has been their experience as I know that he only makes one incision.
