"Recently I had a meeting with Bryson's first grade teacher and the first thing she said to me was "Bryson is the most respectful and polite child I have ever had in my classroom". Wow! What a wonderful compliment.

We have been with the Dojo since near the opening of the school and as I thought about the program, the main thing that came to mind was the character building you offer. Though learning to defend yourself and others when necessary is valuable, your martial arts school goes far beyond technique and skill. Every class offers a valuable life lesson and fosters integrity, character and self discipline while challenging and inspiring each individual regardless of age.

So I share the compliment from Bryson's teacher with you and thank you for the wonderful opportunity you offer!"

- Hope Barnett

Several years ago...

"Everyone at the school seemed to have this cool sense of clam and welcoming attitude that was infectious. They were everything I wanted to be as a shy seventh grader."

Several years later...

"What does it mean to be a black belt? It means that I am the master of my future. It is proof that I am not a quitter. I am a determined human being and no hardship will stop me from gaining what I wish to achieve. It is a reminder of all of the people who have helped me up to this point and all the memories I share with them. To me, it shows the transformation from child to adult."

R. Buchanan - High School student

"The Dojo is the best martial arts school. We have been coming here for seven years now, and it has had a profound influence on me and my son."

- Gail Greene

"My grandson was bullied at school and the teacher did nothing about it. Since my grandson has been training at The Dojo, he stands taller and exudes confidence. I am thankful because he has been able to control his own destiny and protect himself in dangerous situations."

- Faye Curran

"The dojo has helped support the values we have tried to instill in our children. Our 9 year old became a black belt and it improved his confidence. Now, our 4 year old has started training, and is learning skills that will last a lifetime."

- Brittany Singleton

On becoming a black belt at The Dojo - "We all had the same goal. We were all on the same path to reach something that in the past none of us thought we could reach. I have finally achieved that goal of Black Belt, and the maturity and discipline of it as well. Mentally, I can walk around with more pride and confidence than I ever had before."

- Tanner D. Age 13.

"Without The Dojo, and it's society within it, my life would be, honestly, pretty dull. I would not have the disciplined life I have now. I have learned basic morals and discipline in the discussions we have had. Here I am now, with confidence and knowledge, all because of The Dojo's impact on my life." - Anant Ramji - Age 12

"Master Norcross is a fantastic educator. His patience and enthusiasm has made a real difference in our lives."

"The philosophical aspect of training has really helped me with my overall happiness."

"After seven years at another, we switched to The Dojo. The difference was obvious. My daughter has become a leader and teacher, with the skills necessary to keep her safe, because of The Dojo experience."

- Eileen McConkie

"High fives to the leaders at The Dojo. They teach fearless defense, self discipline, respect for others, and a desire for educational achievement. Best of all, the students have great fun in The Dojo classes!"

- Mary Price

"Most schools around here are like playtime gyms. The Dojo is by far the best dojo around."


Younger students from ages 4-7 will have fun working on improving focus, self-discipline, confidence, strength, stranger danger escapes, and how to develop a positive and respectful attitude in school and at home.

How is The Dojo different?

We are not a sport. We are not a gym. We do not compete for points, money, trophies or ego-based personal gain like many sport martial arts do.

We do not break boards or bricks. We break bad habits.

Our martial art is reality-based and extremely powerful at subduing danger. From the first class, you will learn how to defend yourself both physically and mentally, all while having a great workout with new friends.


Start fresh this fall.

This realistic defense method works for all ages and body types.

  • You will learn how to naturally excel in all areas of life.
  • You will learn to be more calm and focused.
  • You will learn several new ways to deal with stress.
  • You will lose weight and gain flexibility and strength.
  • You will become more confident, ready to protect yourself and others, all while you advance towards a black belt degree at your own pace.
