Hello big-daddy I went through New Dimensions/Health for Life they are some of the best doctors in SA, I don't know about BMI. I had Dr. Reiss, have to say they don't have great bedside manner but what I liked is that they always have one of the other associate doctors assist, not some random doctor. So you end up with two really great doctors working on you, which is what I wanted, I was crazy nervous about the operation.
