My name is Jarrett Leiker, I have been practicing karate for 30 years, but I was just like many of you 15 years ago.  I wanted to get better and I wanted make my students better.  But I had NO IDEA WHERE TO START.  I felt stuck.  Well, good news.  The past 15 years I have traveled the world learning from top karate practitioners and masters in both sport karate and traditional karate.  In addition to learning the technical secrets of the top karateka in the world, I extensively studied the human body and its mechanics related specifically to karate.  The results for my students have been incredible.  From World Karate Federation (WKF) Medals to championship titles in open sport karate circuits like the North American Sport Karate Association (NASKA), my athletes are experiencing tremendous success.  Did I mention that most of them live hundreds, and even thousands of miles away from me?  Some even live on a different continent!  How is this possible?  Let me introduce you to the Kata Mastery Online Academy.

"Kata Mastery has changed my dojo & martial arts training forever!"
“Kata Mastery coaches are relentless, they will keep working with you until you reach your goals and they will never give up on you! I would recommend Kata Mastery to anyone I know that trains in traditional kata and wants to elevate their game.”

"There are a lot of positive remarks I can leave. However, if I was to pick just one, it is the positive atmosphere."
My only disappointment is that we didn't have Kata Mastery for my son years ago. Shortly after my son began the program, he would have legendary coaches and competitors stopping him to tell him that they saw a noticeable difference in his performances on the mat. 

There are a lot of positive remarks I can leave. However, if I was to pick just one, it is the positive atmosphere. Positive energy encourages rapid growth. It is transferred from the instructors down to the participants leaving them eager for more. 

My son has tremendous developments in both his athletic ability and mental aspects. Senseis Jarrett, Mason, and Rodrigo continue to learn for their students. They simply care about each one and it exudes. There is no one we trust more!

"She wants to be the best, and this program pushes her to be better and work harder to achieve her goals"
Our family stumbled upon the Kata Mastery program in 2022 when I found a camp they were hosting. Within an hour of the camp starting, I knew this was the place where my daughter truly belonged.

That evening, I couldn’t stop raving about how amazing the day was to my husband. I told him that if we wanted our daughter to progress and succeed, she needed to be surrounded by these incredible people.

At first, our daughter’s goals were to compete and place higher on our national open karate circuit. And she totally crushed it! In less than a year, she was consistently placing top three. We were thrilled! About a year into training with Kata Mastery, our daughter decided to take the plunge and compete at a regional-level NKF-style event. She won gold in her age division, which totally ignited a fire within her. About six months later, she decided to go all in and attend a WKF K-1 Youth League Event. She won three rounds against the best youth competitors in the world in her very first event. She even got a medal at her next event, taking Bronze.

We don’t force our daughter to train. She loves it. She looks forward to every class and lesson with the Kata Mastery Program. Even when they’re tough or when she’s tired. She wants to be the best, and this program pushes her to be better and work harder to achieve her goals. Goals that, thanks to this program, are weeks, months, and years out! When ‘okay’ isn’t good enough, this is the program to push past that. Move to the next level or goal.
