Kettlebell SFG II

Michael Coffin


Mike Coffin was born in Eugene Oregon on October 30th, 1976. 

His martial arts training started at age 16, when he began attending Tae Kwon Do classes in Plano, Texas.

After training in TKD for some time, Mike encountered a professional boxer at his TKD dojo, who introduced him to boxing and kick boxing. This encounter completely changed how he viewed fighting, and skewed him towards reality based fighting, rather than sport fighting. He was quickly enamored with boxing, and began training extensively, eventually competing in local boxing and kick boxing tournaments.

At the age of 18 he was first introduced to ground fighting. The combination of boxing, kick boxing, and ground fighting seemed to be a natural combination proved to be extremely effective. Mike continued to train in all three, until he began training with Allen Mohler. There he began to train with a number of skilled fighters and trainers, and to this day credits Allen with providing him with some of the best ground instruction he has encountered.

In 2006, Mike was looking to continue his training, but was ready to look for a new outlet. After watching some videos on Krav Maga, Mike began training at Krav Maga DFW. He was soon teaching ground classes at KMDFW, and began learning to teach Krav Maga.

In 2009 Mike was certified as a Krav Maga Alliance instructor by John Whitman, and in 2010 he opened the first Crucible Krav Maga location in Garland, Texas at a Life Time Fitness gym. That spring he opened his second location with Life Time Fitness in Plano, and a third location that summer in Allen, Texas.

In the summer of 2010, Mike partnered with Jack Bolowskie, owner of Krav Maga DFW, to expand the Krav Maga DFW business. They opened Krav Maga DFW East jointly in Dallas, Texas.

July 2010, Mike attended his first course with Eyal Yanilov, which substantially changed how he viewed Krav Maga. Eyanl Yanilov, Chief Instructor of Krav Maga Global and successor to Imi, founder of Krav Maga, certified Mike as a Graduate 2 in early 2011.

Since encountering Krav Maga, Mike has made it is priority to seek out the best possible training the world has to provide. It is his philosophy that by pushing ourselves as instructors we are best able to train our students. In the end, it is really about giving our students the best instruction that we are capable of providing so they can save themselves, or protect those in need.

Mike is currently co-owner of Krav Maga DFW East, and owns Crucible Krav Maga, and Chairman of the Board for non-profit P.A.V.E (www.pavingtheway.net). Mike is currently an Expert 1 ranked instructor, StrongFirst SFG level 2 Instructor, and has trained and tested in Israel under Eyal Yanilov.

Javier Bacallao

Javier Bacallao

Javier Born in Cuba and raised in Dallas, Texas since 1993 just picked up a natural allure to fighting, he was granted a 2nd Degree black belt in taekwondo by age 11 when he started at 5 years old, then moving on to boxing when he turned 13 years old. He enjoyed the real competition of fighting other than street brawls where he grew up and school scraps that he got himself in. He attended tournaments all over and with some losses under his belt he kept going to be a two time Golden Glove Champion. Once he thought he was on top he encountered a mix-martial arts fighter named Byran. He was one of the first generation Mixed-Martial Arts fighters before ultimate fighting blew up.

He trained with Bryan for 2yrs learning a little bit of Brazilian Jiu-Jitsu and Muay Thai. Javier was shocked at how much he didn’t know and how easily he could be beaten so he then was looking for another Martial Arts that could teach him to be more than a regular fight could. One day a seminar was held for the show Leverage at the Angelika Film Center and CafT in Dallas where Javier was Managing at the time. He saw a demonstration of Krav Maga being demonstrated by Krav Maga DFW’s own Jack B. and he instantly knew this he could use and remembered that he knew somewhat of Krav Maga through a friend’s father who was a war veteran and ex Commando in the Israeli Army. When he first went to class he found the cardio to be easy but the techniques and stress drills that would be placed on him were too much, he knew this would be the next challenge in his fighting career. He shortly after was trained in Muay Thai by some dedicated Instructors in the art themselves and Brazilian Jiu-Jitsu by Crucible Krav Maga's Owner/Founder Mike Coffin.

Where he went back to fighting and became a Muay Thai Champion in early 2010 and competed in various Mixed Martial Arts competitions where his record is currently 3-1. In the middle of Competitions he also tried to develop his Krav Maga and became an Instructor with Krav Maga Alliance and has been through Level 2 Instructor and as he thought he was reaching a peak in his training he then was introduced to KMG (Krav Maga Global). Where Krav Maga all began with Imi he was now training with Imi’s First Disciple Eyal Yanilov and the Krav Maga Global Team. He then flew down to California again but, when flying back he was KMG certified. Now he trains harder than before to become the best and most effective Krav Maga practitioner for himself and his students.

Javier has completed parts 1, 2, and 3 of the KMG instructors course, and currently ranked a Graduate 4.
