Dr.Coufal~ I've seen him for a 2nd surgical opinion and thought him an excellent choice for this even though I didn't pick him rather WC did back in '06. He was very thorough as I would expect of a Neurosurgeon, spent enough time with history and physical and answered questions easily. He has an excellent reputation.
I've also seen Dr.Delamarter and Dr.Regan in the LA area. Both are Orthopedic Surgeons, both with excellent repuations and pretty much all 3 surgeons agreed on course of action.
Ultimately I did not have surgery although felt very comfortable that all 3 surgeons were agreeing on surgical course of action pretty much.
good luck
