Hi NJ,
Yes I knew that Dr Bierstedt and Malte had connections with R-L. And that they had a fundamently disagreement with their practices. BTW Dr. Clavel also had connections with R-L.
I went with Dr. Biersted based upon a number of factors.
BTW ... If you can find a doctor that will guarantee success of your back surgery GO WITH IT!
They offer no guarantees.
