Our mission is to empower individuals with the confidence and ability
to fight back against the threat of victimization

Unfortunate statistics reveal the need for this mission. In the U.S. alone, every 2 minutes, someone is sexually assaulted. In fact, 1 in 5 women will be sexually assaulted in their lifetime. It is a disgrace that so many innocent lives are damaged, or even lost. The real tragedy is that such ruin continues

MUNIO was born of my firm conviction that we all can stand up for ourselves and fight back against a criminal attack.

MUNIO Self Defense is actively partnering with other leaders and organizations worldwide that align with MUNIO’s mission –

A Message from the Inventor

Over the years, I have encountered victims of rape or other criminal violence. Sadly, those victims came to me for help after they had already been victimized. Unfortunately, that's far too late. The damage is done, and many are still plagued by that terrible incident.

I was so disgusted with innocent people being harmed that I felt compelled to create a self defense product that just about anyone can use for protection. I discovered the solution by integrating my professional skills as both a martial artist and a graphic designer. I combined the appeal of "designer style" with the simplicity and versatility necessary in an effective self defense product – and created the MUNIO Designer Self Defense Keychain.

I firmly believe everyone should have the ability, and the confidence, to fight back against an attacker.

Now you can.  STAY SAFE!       


My Dedication

I dedicate MUNIO to the memory of my brother Mike. He lost his life after a horrible fight,
yet Mike still strengthens my future and my vision each day.

I pray that MUNIO's contribution to public safety will honor him.

The development of MUNIO has been a long and challenging journey.
I owe my deepest thanks to my parents, my family and Michele for their considerable support.
