Kru / Professor / Coach Adam Jones

Professor Jones is a rare instructor who's not just knowledgeable in one aspect of combat sports but he's become very proficient and competed in multiple as well. He was a Competitor for Team Canada multiple times (as a Striker and as a Grappler), Medaled at Multiple World Championships (as a Striker and a Grappler), Coached at Multiple World Championships (for Striking and Grappling), trained, taught and competed all around the World with Rumble Martial Arts home-grown Keswick Athletes in places like Thailand, Abu Dhabi, Africa, Philippines, Dubai, China, Mexico, Ireland, all across Europe, America, Canada, etc. 

A big life changing moment for him was August of 2011. His trainer, manager, mentor, friend and even roommate for multiple years, Shawn Tompkins, passed away suddenly at the age of 37. He had two separate funerals (one in London Ontario and one in Vegas) because he was such a big name in the Combat Sports world. His funeral in London was held in a big theater and it was packed. It was ‘standing room only’ and even the parking lot was packed during the service because the theater was full. 

It was at Shawn’s funeral and thinking about the giant impact that he had on Prof. Jones’s life and  the lives of so many others that Prof. Jones decided that he wanted to open a gym in his hometown to try and have the same impact on his home community in the same way that Shawn had on him (and so many others). Shawn passed away in August of 2011 and our first gym location in January 2012.

Coach Jason

Jason’s martial arts journey started as a secondary sport after spending 7 years in Europe playing rugby. He took Brazillin Jiu Jitsu as a way to stay in shape during the off-season, but during that time he became hooked on grappling and it quickly became his new passion. After competing and winning his first white belt tournament 2 weeks into training, he began training and competing in amateur kickboxing and Muay Thai events. As time went on, the next logical step for Jason was to enter MMA. Now a veteran of 7 MMA fights from multiple federations, Jason is still actively competing and enjoys sharing his experience with others in the classes that he teaches.


He has won an MMA Championship Belt from Flo Full Contact Productions in New York and a whopping 3 MMA Championship Belts from Victory MMA also in the United States.

Coach Spencer
Coach Spencer

Spencer started his journey in martial arts as a teen, training in Kickboxing, Judo, Krav Maga and Jiu Jitsu. The training got put on pause while “life and partying” kicked in.

After a lot of deliberation and procrastination, Coach Spencer took all 230lbs of himself to Rumble Martial Arts to resume the martial arts journey.

As of 2020, he is the quickest student to receive his BJJ blue belt and is an active competitor. Coach Spencer has dropped 70lbs to reach 160lbs and hasn’t looked back. He now looks to use his story to help anyone in search for themselves and some guidance.
