Jason Powell – Brazilian Jiu-Jitsu

With more than 12 years of training experience Jason has developed tremendous ability and technical skill in the art of Brazilian Jiu-Jitsu. He possesses a very unique and exciting style builds upon a solid understanding of the basics with movements that are fun and highly effective.

A a Brazilian Jiu-Jitsu competitor Jason excelled throughout his competitive career, winning gold medals at many prestigious tournaments over the years including the Arnold/Gracie BJJ Championships, the Canadian Nationals and the Joslin’s Canadian Open.

Jason has a strong passion for teaching and loves passing on his vast BJJ knowledge to others. His wit, and bad humor keeps people on their toes and the exciting way that he teaches class has his students deeply engaged from start to finish. Every person that steps onto the mat to train in his class is guaranteed to learn things correctly due to the large amount of time and focus Jason gives to all.

Dave Mark – Brazilian Jiu-Jitsu

Dave has been involved in athletics for most of his life. An early passion for weight lifting developed when he was in his teens and at 38 years of age Dave began training in the martial arts. The first discipline he studied was Karate; Brazilian Jiu-Jitsu followed soon after and he`s been training in it ever since.

In 2001 Dave earned his black belt in Karate from Rick Joslin and 14 years into his training he became one of Jeff Joslins first 2 Brazilian Jiu-Jitsu blackbelts.

Dave`s love for the art of Brazilian Jiu-Jitsu is obvious to all who share the mats with him. At 50+ years age, the young guys may at first think they`ve got the upper hand on Dave due to there youth, speed or intensity. Moments later they know differently as they are swept, twisted and squeezed into submission by the humble and incredibly skilled BJJ Black belt.

Dave BJJ classes are fun, challenging and very motivational. His ability to break down techniques into the smallest of details leaves everyone that attends his lessons with some new and exciting tricks on the mat.

An important part of the team Joslin, Dave has helped many our our students achieve their personal goals both on and off the mats and is an inspiration to many.

Dean Massicotte – Brazilian Jiu-Jitsu

Dean’s martial arts journey began when he was a young child with both karate and boxing training. In his early twenties, after watching the UFC for the very first time, he immediately had an interest in learning the art that Royce Gracie was using to dominate every one of his opponents inside the octagon.

Assessing his already well established martial arts skill set, he knew there was something missing. He felt strongly that he had to learn how to fight on the ground in order to be a complete martial artist. His search for real grappling skill led him first to Judo and when he later moved to Hamilton he quickly found Joslin’s and has been an important member of our team ever since.

“What I noticed right away about Joslin’s was the friendly atmosphere, competive spirit, and Jeff’s passion for the sport and his desire to constantly learn and improve his skills.” says Dean. “I’ve never trained with anyone with so much desire and dedication before, and felt really lucky to be here.”

Dean won many medals and championships over an eight year competition career and eventually achieved the rank of Blackbelt –one of the first two BJJ black belts Jeff had ever awarded– in the art after more than a decade of training.

He then began to focus on teaching the art, giving back to the students at Joslin’s by bringing out the best in them on the mats. Always emphasizing a solid understanding of the basics, mixed with the development of the innovative skills of an art that is constantly evolving, Dean teaches his lessons in fun and exciting ways.

Dean states “I also like to encourage students to step outside their comfort zone, and spar people that will give them a challenge. This will prepare them mentally when they have to compete, or defend them selves in a real life situation.”

Dean is a valuable asset to the Joslin’s Brazilian Jiu-Jitsu Team and he has helped many of our students achieve both their competitive and non-competitive goals in the sport.
