Dr. Atkins is 2nd rated but his bed side manner is rough. When I was checking out all the doctors a lady passed out,( it was over 100 out side) He did nothing, not even stopped talking or call 911. Then Dr. Tang is 1st. Very strict! If you don't lose what ever amount of weight he sets he will not do the surgery, very strict diet before and after. And I went with Dr. Umbach. His staff is caring and kind. He answered all my questions took time with me. He walked in wearing blue jeans and flip flops.
