Founder, Chief Instructor

 

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 was co-owner of Krav Maga DFW East, and owns Crucible Krav Maga, and is on Board of Directors 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. His credentials include:

KMG Krav Instructor Expert 1

Primal Move Instructor

Functional Movement Systems FMS 1 & 2 certified

Tactical Combat Casualty Care (TCCC) certified
