He may take awhile to get back to you. He doesn't have the admin team that the others have. But you are buying the surgeon, not the team. Feel free to politely follow up with him. Good luck.

Rischke
 

So I got another opinion. Dr Rischke suggest also 2 level ESP disc same as Bierstedt. For more information I need to pay 450CHF. I wonder who is cheaper and/or better, Rischke or Bierstedt?

Clavel and Desai
 

Hi everybody,
so I have contacted also Dr. Clavel and also Dr. Desai. Dr clavel would also make 2 level ADR. Dr Desai need first to receive my CDs to make evaluation but looks like everybody make the same opinion over me.
Since I chosen ESP disc Dr Desai is my favorite I think also because he don't ask fortune for surgery. In Czech republic salary is much lower then in USA. But I am scared to make final decision also. Thursday I am going for DEXA test.

They're all good surgeons from what I hear. I don't think you can make a bad choice between them.
