Kajan Johnson grew up in Burns Lake BC on the traditional land of the Ts'il Kaz Koh First Nation. A somewhat troubled youth, he made the move to Prince George to live with his father after being expelled from the only high school in the district. It was here in Prince George that he discovered martial arts. Kajan began to work with coach Bill Mahood out of PG Fight club as a high school senior and after just two months of training decided to begin fighting professionally. He fought out of PrinceGeorge for 4 years before deciding to make the move to Vancouver in order to seek out world class level coaching and knowledge.

After moving to Vancouver Kajan established himself at the invite only professional training facility, Revolution's Fortress. Finally having access to elite level training Kajan thrived, going on a 6 fight win streak that culminated in winning the XMMA lightweight world title.

Always seeking elite instruction, Kajan decided his next move would be to Montreal to live and train at the famed Tristar Gym Montreal under Firas Zahabi, coach of UFC champion GSP (George St. Pierre). Living in Tristar Dorms and Training at Tristar gym, Kajan immersed himself in knowledge. After 2 years he was accepted to compete in the UFC's tournament, The Ultimate Fighter Nations Canada vs Australia. He did extremely well which lead to the UFC signing him to a contract after the tournaments completion.

Kajan's first UFC fight was a back and forth war which, although he lost, earned him Fight Of The Night honours and most importantly taught him great lessons. With these lessons, Kajan began to, for the first time, develop his own fighting system. The system encompasses and addresses all distances and positions that are possible in mixed martial arts. It is both defensively and offensively sound and uses a wide range of techniques from many different art forms. Since developing and utilising this system Kajan is undefeated in the octagon and is gaining momentum to make a run for the UFC Lightweight world title.


Rochelle was born in Winnipeg, Manitoba and began her gymnastics career at the very early age of 2. When Rochelle was 7 yrs old, both her parents decided to uproot the family and move to Leeds, England, where her father finished his PhD at Cambridge and Oxford University.

Rochelle continued her gymnastics career and at the age of 9, became a member of and competed internationally for the Great Britain Gymnastics Team. In 1996, Rochelle became the Great Britain National Gymnastics Champion and retained the title for 3 consecutive years.

Rochelle was also nominated and awarded 'The Top Sports Person in England under the age of 13 category,' for 2 consecutive years. At the age of 14, BBC produced and aired a one hour documentary called 'Going for Gold,' focusing primarily on her goals of competing in the 2000 Olympics. Unfortunately, her dreams fell short when the International Gymnastics Federation (FGI) announced that a competitor must now be 16 years of age to compete in the Olympics. Rochelle was turning 15, and sadly, was one year shy of being eligible to qualify.

With the Olympics another 4 years out of reach, her family decided the best thing to do was pack it in and return to Canada, in the hopes that Rochelle would continue her career on the Canadian team. She, however had other plans. Rochelle, resigned from gymnastics, focused on her studies and graduated from Terry Fox High School a year early at the age of 16.
