Quickly: Roy Marsh is a good friend of mine, a great guy and a tremendous teacher of Gracie Jiu-Jitsu. He has graciously offered to teach a seminar at the gym I attend to benefit two great charities. It’s a $20 minimum donation, which makes it possibly the best value seminar of all time.
If you have trained with Roy, you know how good he is. If you haven’t, you owe it to yourself. Come learn great stuff and help out great causes.
