Things that you should take away from a MoM seminar

You are not as smart as you could or should be. 

Things are not always simple, despite what TV has told you.

Don't make things more complicated than they should be.

You're not a good as you can be, but afterward, you will know how to be.

A really good sense of humor is way more dangerous than a hot temper. 

Settle it quickly, Speed equates innocence. 

Bruises, yes a lot of bruises.

How to train in more efficiently and effectively.

This and so much more.

What are we training for?

You have to get past 'winning vs. losing', that has no place in this. We need to remove that from our brains.
We don't train for the bar room brawl, we don't train to win monkey dances. That isn't survival, that is ego games and jockeying for position.

We train for that which you cannot deescalate, the ambush, the nightmare. we train to go home, or to be the one to act so others can go home, if that's what it takes.

What we do

What will I learn if I come to a MoM seminar? 

We don't have a a clue! Why do we say that? Because we don't know what you already know, what resources you already have and what preconceived ways you already think.

What we present is the culmination of over 100 years of combined knowledge earned through bad situations and bad choices that the three of us have survived.

What we aim to have you learn is a way of thinking that can save your life.


If violence happens, it happens sudden and closer, faster, and more forceful than you've ever encountered before. You'll be in shock, possibly frozen, and overwhelmed, while under assault.


You need a laywer, one who understands the realities of self-defense and how to protect you, from the criminal prosecution and the civil lawsuit.


The aftermath of a violent assault is costly: bail, lawyers, time off from work to meet with lawyers, the court case(s). You may lose your job or livelihood.


Using violence changes your life, and your self. What you did to protect yourself, your loved ones, or others, is a change. How you see yourself, how others see you, changes you further.
