    About Gideon

    Gideon started kickboxing at the age of 21 at one of Dutch finest full contact gyms, Matuari – Gaya Tulis (Amsterdam, The Netherlands). At that time Gideon trained with many champions (Gerold Mamadeus, Youssef Akhnikh, Redouan Cairo to mention a few), who teached him the art of Thai/ Kickboxing. Owner & Trainer Chris Tulis is known of his techniques and until today that is still the basis and a huge part in Gideon’s training.

    Gideon was about to have his first fight representing Matuari, but an unfortunate situation during training caused him a dislocated knee. Which happened more often than once and had to postpone his first ring experience. After Gideon moved to Haarlem (NL), he trained for a short period at Riduan El Assrouti from Gym Haarlem and when he moved to Curacao he started training at Baas Sports by Edwin Baas. Gideon made his debut at the age of 31 in a boxing match and has fought a total of just 4 fights in his “career”.

    Due to a damaged hip, Gideon was not able to continue with competition, but his experience, knowledge from above mentioned gyms, people skills are very useful as a trainer. Gideon started teaching at Baas Sports and it was well received by most of the practitioners. After a while Gideon started his own gym (PRO-FIT Curacao) with a former sparring partner, who knows Gideon as the only one who hit him hard with a liver punch. Gideon’ management, financial & marketing experience including his Martial Arts experience was the best combination for a successful gym. He left the financial offshore industry behind and started full time in the Martial Industry, including being a promoter (HONOR Fight League) and sports management (Jonker Sports Management).

    Due to a change in vision, Gideon decided to leave PRO-FIT and started IMMARTIAL – Athlete Centre, whereby the focus will be on quality, a “house” where everybody will be treated equally and where everybody is welcome. Respect is the backbone of IMMARTIAL and one of the reason for existence and continuity.

    Gideon goes at least once a year to another well respected gym to educate himself. Some of the gyms/ trainers he trained with are:
