Dr. Chee K. LingSenseiLing 

Sensei Ling is the chief instructor and founder of Delta Martial Arts. Also a family physician and clinical professor for UBC, Dr Ling has been practicing martial arts for over 55 years. He started Judo in 1962 before beginning karate training in 1970 with Sensei David Akutagawa who achieved his eighth degree blackbelt directly from Mabuni Kenie Soke, the eldest son of the founder of Shito-Ryu Karate.  Alongside his Karate studies, Dr. Ling also pursued Iaido from 1987.

While living in northern B.C., he helped establish, and was senior instructor of the Kitimat Karate Club for over 15 years. Now,  Dr. Ling’s focus of instruction is on teaching Blackbelt level Karate, Iaido and Kobudo weapons to adults. The curriculum of Iai he currently teaches is Eishin Ryu Iaido, Takeda Ryu Iaido and Seitei Iai. The curriculum of Kobudo he teaches is Ryukyu Kobudo in Bo, Jo, Tonfa, Sai and Kama.


  • 7th degree blackbelt in Takeda Ryu Iaido
  • 6th degree blackbelt in Eishin Ryu Iaido from Dai Nihon Iaido Renmei (DNIR).
  • 6th degree blackbelt & Shihan in Renshikan Shito-Ryu Karate.

Dr. Ling served as Secretary of the National Karate Association, member of the World Medical Commission of the World Karate Federation (WKF), and was a top National A Level Referee. He was also Director representing the sport of Karate on the Canadian Olympic Committee for 17 years.

A motto he lives by is, “The pen and the sword are best kept in accord.” This means that one persons academic studies and studies in physical activity must be balanced.  For if someone focuses on academic studies and not their physical activity, they will not do well in sports.  Same if someone focuses too hard on their physical activity they will not excel academically.
