Thru The Fire Training Organization

“THRU THE FIRE is my unique expression of what I have learned and am continually learning from my instructors, students and friends. My sincere gratitude to them all. Without each one, the journey would not be nearly as complete or rewarding. It is my privilege to walk with them.”

— John D. Koeshall


You Must Be Tempered If You Want To Endure

Metal is tempered through exposure to high temperatures to harden it and enhance its ability to hold an edge ... so too must your Mind, Body and Will be tempered through controlled exposure to differing levels of “heat” (stress and pressure) during training.

This process of putting yourself Thru The Fire will allow you to assure your ability to hold your edge during a high stress encounter or violent situation.

Training in this manner is the best way to prepare you to get Thru The Fire of conflict.

John, wish I could have trained with you when I was younger.  I would have saved a lot of time and money.  Your students are lucky.  All the best mate.

James L.

Excellent instruction as usual.  Thank you so much for bringing integrity to a sport so full of ego maniacs.  I send links to your videos to all my 'fight friends'.

Nikolaos V.

I very much like your class.  You explain everything so that I can imitate everything well ... my movements have improved 1000% since I started training with you!

Train as my private student, but do it from your own home ... on  your time!

I studied under John for 14 years, this included him visiting the UK over 30 times as well as us training and teaching in Sweden, Canada and the U.S together.  

When we met I had already been studying 30 years, I had no idea the depth of John's knowledge and ability to change what I had!  I’ve never had an instructor invest so much time into me and influence me not only in martial arts but also mentor me in life.

Because of the training I did with him, I was able to become an instructor under Guru Dan Inosanto, Guru Lonero and Guru Terry Barnett.  I would never of been able to gain any of these instructorships without John Koeshall.

Learn from him, absorb all you can and trust his process.

As I teach daily, I hear all of John's “gems” come out of my mouth and it always makes me smile.

He is a rare breed and you will be blessed having him as your teacher.

Hello, Being a Project Manager for an engineering company, I found John's teaching to be professional, and well structured.

He was able to explain details from a perspective that allowed me to quickly grasp them.

As a Wing Chun practitioner, and instructor, I found it very refreshing that he never belittled the art that I have trained in, but rather encouraged my training in Wing Chun. 

John encouraged me to look at my Wing Chun through two differing points of view:
1) As an art (with it’s rich culture and tradition), and
2) What is functional and practical.

I personally enjoyed the Kali (Filipino Martial arts) instruction.  Not having a background in Kali, John was able to bring both a patience and great depth of understanding in teaching the foundational points of the art to me.

... And the practical teaching of real knife defense was refreshing.

Thanks for the great experience!  I look forward to next time!

The creator of this video added pieces of other videos from my YouTube Channel that don't necessarily depict what I was talking about.  I would never characterize "my style" as Rapid Assault Tactics, but I do teach that system as an integral piece of my training curriculum. 

This video was filmed while we were living in Thailand.  Now we are living in the USA, but we plan to make regular trips back to Thailand, and other places, as time and travel restrictions allow.
