Chinese,
I got your message but for some reason could not reply (maybe because I am not a pro member?). In any event, I do teach Combat Sambo but, I am not affiliated with Fighthouse. Nevertheless, I highly recommend David Rudman's Sambo program. It is a rare opportunity to be able to train with someone of his experience and skill level. You will learn a tremendous amount. Drop me a line if you still want to chat americansamboassociation@att.net
Peace,
Steve
