Realistic, evidence-based self-defense training

I’m Brigitte Schulze Martinez, and I founded 3 Rivers Defense in 2009. After three years of going back and forth between Montana, USA, and Patagonia in Chile, I’m now back full-time in Montana.

For over 16 years, I’ve been committed to providing research- and evidence-based self-defense coaching.

My focus is on holistic, trauma-informed training, based on our instincts and intuition.

I am a SPEAR ® self-defense trainer, an Evidence Based Scenario Trainer, and a Be Your Own Bodyguard ® coach, all certified by Blauer Tactical Systems.

Looking back to 2024, my overwhelming emotion is gratitude for our students and for our Blauer Tactical, Inc. worldwide training community. I’m happy to report that out of all affiliates worldwide, I received the Blauer Tactical Inc. first prize for teaching the most students and hosting the most events in 2024.

For 2025, I’m excited to continue offering private self-defense training and Be Your Own Bodyguard ® courses by appointment.

Sound journeys and sound healing

I’m also a certified sound practitioner, and I am thrilled to provide sound journeys and sound healing as part of our holistic wellness program. Everything is energy and vibration.

Stress and trauma can cause dis-ease. Sound has an undeniable effect on the body. It is a potent anti-dote to stress and anxiety, promoting calm and relaxation. Sound baths are a foundation for holistic wellness.

A calm mind is also a fundamental component for all phases of effective self-defense - threat detection and avoidance, de-escalation, and fighting back as ethically, morally, and legally appropriate.

Thank you to everyone who joined our Sept. 7th sound journey! Our next Bozeman sound journey is at 5pm on Sunday, Oct. 5th, 2025.

What our sound journeys are about

We focus on living life with harmony and joy.

Intentional sound can create a harmonious balance of our physical, mental, emotional, and spiritual bodies. It can provide deep relaxation, release, realignment, and restoration. It can nurture joy, holistic wellbeing, and peace. People with an harmoniously aligned body, mind, and spirit, as well as deep self-awareness and relaxed situational awareness are better able to protect themselves. That’s why I combine self-defense and sound experiences. Some people consider this combination odd; others intuitively grasp their inherent complementary nature.
