Sensei – Tom Mah

– Owner & Chief Instructor –

Sensei Tom Mah was born in Canton, China in 1954. Soon after that he and his parents, along with his older sister, moved to Hong Kong. Four more siblings came during his time in that city.

Tom was first introduced to the martial arts by a family friend. This friend practiced Tai Chi Chuan and had demonstrated his art several times to the family.  He was an avid reader of martial arts novels in his childhood days and frequented cinemas where kung fu movies were in abundance. But interestingly, even with his huge attraction to the martial arts, Tom had never contemplated on taking kung fu during his early years.

In June 1964, Tom and his family immigrated to Canada and resided in the town of Smithers. The following year the family moved west to a coastal fishing town call Prince Rupert, with a population of several thousand. Although very shy in conversation due to language differences, the school years still found Tom very involved in athletic programs in which he excelled: volleyball, track and field, tumbling, badminton, table tennis, and wrestling.

Tom completed his high school in Prince Rupert then attempted higher education at the University of British Columbia in 1975 with the ambition of pursuing a career as an architect. It was while attending university in 1976 that he was introduced to karate by two friends. The dojo was of a Shotokan style under the direction of Sensei Norman Welsh, a sandan at the time. It was love at first try. Something clicked with him the first day, though he is not sure what it was. Perhaps it was the rigorous and intense workout, it may have been the speed and power of the movements demonstrated by the instructor or the graceful movements of the katas, or it could have been the combination of all these things. Regardless Tom found himself drawn to this discipline like a bee to honey. Little did he realize that this was the beginning of a whole new way of life totally different than what he had set out to accomplish in university.

After 1½ years in UBC he left university for a position with a supermarket chain in Vancouver. Karate also took a back seat for about a year. In 1978 Tom moved back to Prince Rupert and there he joined a local Chito-Ryu dojo under Sensei Bill Pitcher, who was a student of Sensei David Akutagawa, the vice-counselor for the Canadian Chito-Kai Association at that time. That same year Sensei Pitcher left for an RCMP position in Vernon and Sensei Mah found himself studying directly under Sensei D. Akutagawa from that time on.

Sempai – Sally Plimmer

– 2nd degree black belt-

I started doing karate when I was 23 years old. Like many young women, I wanted to feel like I could defend myself if I ever got into a bad situation. When my husband and I moved to Canada, we were introduced to Sensei Mah and started taking lessons with him within one month of moving here. We were lucky enough to be able to attend the regularly scheduled classes, but were also afforded the opportunity to attend many private, one on one lessons with Sensei Mah which we benefited from greatly.

In April 2000 I became pregnant with my first daughter and tested for my blue belt at 6 months pregnant. I took some time off from training to spend time with our new family, but got back into karate about 2 months after Bethany was born. She was a regular spectator at many karate classes, crawling and eventually toddling around the dojo during class.

By the time I became pregnant with our second daughter I was at brown belt level and found it very difficult to train through this pregnancy. I took about 3 years off from karate and struggled to come back. But once I made up my mind to do it, I was determined and made myself attend classes regularly again.

“I have always been interested in Martial Arts but it wasn’t until I met Sensei Mah and the other black belts at TMSK that I took the plunge.  I immediately had a great feeling about the school and I’ve been training ever since.  Karate has become a very important part of my life.  Not only has Karate given me invaluable skills and confidence, it has given me a great group of friends to train and learn with.”



Stephanie ApplebySempai – Stephanie Appleby

– 2nd degree black belt-

Instructor – children classes

Martial arts student since 1991

Earned her 1st degree black belt in 2011

2nd degree black belt – June 2015

“Stephanie Appleby started training with Sensei Mah in 1991. Karate began as a fun activity for the whole family, but has developed into a part of her. Karate has had a large influence in many aspects of her life, including helping her become the person she is. For Stephanie, karate is about challenging herself and learning new skills. Because there's always more to learn, Stephanie continues to strive to improve her skills.

Due to her schooling, traveling, and work Stephanie found it difficult for many years to maintain her training long enough to test for her black belt.  But perseverance finally paid off in June of 2011 when she was finally able to settle back in Kelowna to pursue her martial arts training.
Teaching the kids classes are also an important part of her karate training. Along with the challenges it brings, seeing the children develop as karatekas and as people is incredibly rewarding.
Stephanie also trains in Kobudo (Bo, Sai, Nunchaku, Tonfa) and Iaido (a sword martial art).”
