United Surgical.Staten Island..anyone use it?

Hi all:  I'm about to look into weight loss surgery and I live in Staten Island.  Was wondering if anyone had their surgery through United Surgical?  Are they good surgeons for this type of surgery. 

I heard of Dr. Nicastro or Dr. McCullen.  Any one know of them?

Thanks for any responses you can give to me.
