BJJ Seminar Success!!! A lot of people came out for the First of the Grow and Share the Arts Seminar Series - Dave Mark BJJ Seminar. Professor Dave Mark of Joslins MMA in Hamilton, Ontario - led the seminar as he covered a lot of Brazilian Jiu Jitsu basic/fundamental techniques to the eager audience. Many interested instructors attended from respective schools across Trinidad and Tobago. Hope to see many more at the next seminar. Keep training!
