Note - here is a link to an updated post about Steve Lavallee.
About a decade ago, Kyoshi Steve Lavallee started training at the Gracie Academy in Miami. He has enjoyed it and incorporated some of it into our curriculum at the dojo.
Here's Kyoshi's demo of Jiu Jitsu self defense that he gave at a recent Black Belt Spectacular (Parker Playhouse, Broward County, Ft Lauderdale). Great stuff.
