Grandmaster Timmerman began training in Holland, where he was born, and continued to practise in Canada after his family moved there in 1958. Originally he studied Jiu Jitsu and Catch as Catch Can, but when that was not available to him in Canada, he began to study the arts of Kuk Sool Hap Ki Do and Tae Kwon Do under Grandmasters Pak In Shyuk and Pak Sung Bok. After a split occurred between GM Pak and GM Suh In Hyuk (who signed the original certificates Grandmaster Timmerman earned), GM Pak founded the art of Kong Shin Bup™. Other than heavy fitness and breaking requirements, the art was essentially the same as the old Kuk Sool Hap Ki Do, but the name was changed to avoid trademark issues.
After Grandmaster Pak left the area, and KJN Timmerman was left without an Instructor, he sought out GM Suh In Hyuk in order to continue his training. He eventually became the Master in charge of Canada and the State of Michigan for the World Kuk Sool Association, and he worked diligently to spread the art of Kuk Sool until 1998. He never stopped looking for his original Instructor, and in 1984 he found Grandmaster Pak in Edmonton, Alberta. There he worked for several months with Grandmaster Pak to train and help Grandmaster Pak finalize the Kong Shin Bup™ curriculum. While there, he tested and was promoted to 8th dahn Kong Shin Bup™ by Grandmaster Pak. Before he left Edmonton, and because GM Pak had founded a new martial art called Tae Keuk Do, Grandmaster Timmerman was appointed as the Inheritor of Kong Shin Bup™. He immediately registered the name with the Canadian Government and trademarked the name.
After Grandmaster Pak passed away, and after he left the World Kuk Sool Association, Grandmaster Timmerman took over the leadership of Kong Shin Bup™ and began to further develop the National Korean Martial Arts Association he had founded in 1973. Since then he has assisted Korean style martial artists and school owners around the globe with training, testing, and certification without politics or unreasonable demands.

Jiu Jitsu: (certificate #3377)
Master Timmerman earned a fifth degree Black Belt in Nihon Jiu Jitsu by the International Martial Arts Federation (IMAF) signed by the late Shinsaku Hogen Hanshi. Master Timmerman also received fifth degree Black Belt recognition signed by Professor Richard Morris, Hanshi, from the Jiu Jitsu International organization.
Kuk Sool Hap Ki Do: (certificate # A-6011)
During the late sixties and early seventies, Master Timmerman received his first, second, third and fourth degrees in Kuk Sool Hap Ki Do. These certificates were sent from Korea signed by Grandmaster Suh in hyuk and countersigned by Master Pak in shyuk. Shortly after, GM Pak switched to teach the art of Kong Shin Bup™.
Kong Shin Bup™ Hap Ki Do: (certificate # 106)
GM Timmerman continued to study hard to earn his 5-6-7th dahn in KSB, and in 1984, Master Timmerman was promoted to eight Dahn in Kong Shin Bup™. At this same promotion, GM Pak asked him to take charge of Kong Shin Bup™ and gave him the seals to the art. Kong Shin Bup™ is a registered trademark owned by GM Timmerman.
Out of respect for his Grandmaster, KJN Timmerman did not assume his rank and position as Grandmaster of Kong Shin Bup™ until after its founder, Grandmaster Pak, passed away in 1995. Shortly after, Grandmaster Timmerman’s rank and position as inheritor of Kong Shin Bup™ were recognized by the Korea Kido Association, World Kido Federation, and the WHFS Grandmasters Council.
Kuk Sool Won: (certificate # A-6011)
During the late sixties and early seventies, Master Timmerman received his first, second, third and fourth degrees in Kuk Sool Hap Ki Do. These certificates were sent from Korea signed by Grandmaster Suh in hyuk and countersigned by Master Pak In Shyuk. Shortly after, GM Pak switched to teach the art of Kong Shin Bup™.
After joining the WKSA, GM Timmerman was demoted to 4th dahn in Kuk Sool; however, his old dahn number remained the same. Since he was not a rank chaser to begin with, this demotion did not bother him at all. In fact, he was proud to become the classmate of Master Sung Jin Suh, Marlin Sims, and Jay Lee. The four of them tested for and were promoted to 5th dahn in Sand Francisco, and years later they were promoted to sixth dahn at the World Kuk Sool Championships in Houston, Texas.
In 1998, GM Timmerman left the WKSA to focus on promoting the art of KSB and the NKMAA. As he took charge of KSB, he also began using the rank (8th dahn) he had earned earlier under the founder of that art. Since GM Pak had passed away, he became comfortable with the idea that 8th dahn would be his highest rank.
Han Min Jok Hap Ki Do: (certificate # 4-9-7)
Always eager to be a student, GM Timmerman sought closer relationships with GM Seo In Sun, who had earlier appointed him as Canadian Director of the Korea Kido Hae. During a visit to Korea in 2004, Grandmaster Seo totally surprised KJN Timmerman by promoting him to 9th dahn. GM Timmerman had not planned to attend that year, as finances would not permit it. Unbeknown to GM Timmerman, his student, KJN Kevin Janisse (aware of the pending promotion), organized a fundraiser, and the trip was on. NKMAA members often traveled to Korea to participate in the bi-annual World Hap Ki Do Championships, and our last group totalled more than 50 participants.

KJN Timmerman’s skills have been recognized by, and he received numerous awards from, all levels of Government, including, but not limited to: Prime Ministers Jean Chretien and Steven Harper, as well as the Canadian Ambassador to the UK, several Mayors, and the Military of the US and Canada. He also received keys to several cities and accolades from high ranking Martial Artists around the globe, and he has been featured on the cover of several Martial Arts Magazines. That his peers value his knowledge is amply demonstrated by their many requests for him to conduct seminars in all parts of the world.
