From the Igor Kurinnoy/Boretz website:

June 27 – July 7 in the United States of America in the Bettendorf city (Iowa) and San Francisco (California) series of international seminars was held by Igor Kurinnoy. It was good opportunity for many sambo and judo players to learn throws, grappling techniques, submission with focus on leg locks, theory of training and conditioning presented at the “Sambo for Professionals” directly from the source. This vent became possible owing to official SFP representative Gregg Humphreys efforts (travel and event organizer) and Serge Gerlach (for California event).

nice to have a little write up in the heartland of sambo.
