About David Martin

For over three decades, I’ve been driven by a simple but powerful purpose: to share knowledge that makes people better at what they do — and safer while doing it. My journey has taken me from the front lines of municipal law enforcement as a Senior Police Constable and Coach Officer, into the classroom as a College Professor, and across corporate boardrooms as a Security Trainer and Manager.
What’s never changed is my commitment to delivering practical, real-world skills to professionals who need them most. Whether I’m working with new hires, seasoned teams and executives, I focus on building confidence, sharpening judgment, and preparing people to respond with clarity and control.
Training isn’t just what I do — it’s what I believe in. Because when people are equipped with the right tools, they don’t just protect others — they elevate their careers, their teams, and their communities.

Founding Martyn Styra Training Concepts was the natural next step — a way to bring together decades of experience and a lifelong passion for teaching, so I could help others lead with confidence, clarity, and control.

Local Expertise. National Reach.

For over 30 years, my work has been rooted in the Toronto and Greater Toronto Area, where I’ve trained professionals across law enforcement, security, and public services. Through training agreements and affiliate partnerships, I’ve extended that reach across Northwestern, Eastern, and Southwestern Ontario — and soon, to California USA.
The concepts I teach aren’t confined by geography. They’re built on universal principles of safety, accountability, and tactical readiness — making them relevant and adaptable to teams across Canada and beyond.

Client Transformation

Our goal is simple: to ensure every participant walks away with real, usable skills — not just a certificate. Clients leave our sessions equipped with practical tools they can apply immediately in their roles, from conflict resolution to incident response. This isn’t box-check training. It’s valuable, transferable knowledge that strengthens performance, boosts confidence, and makes teams safer and more effective every day

Before and After - Global Security Client

Before Training:
A frontline security team from Toronto was struggling with inconsistent responses to incidents. Staff lacked confidence in de-escalation techniques, communication was reactive, and tensions often escalated unnecessarily. Incidents were frequent, documentation was weak, and morale was low.
After Training:
Following a customized program focused on subject control, situational awareness, and de-escalation/conflict resolution, the team saw a measurable drop in incident frequency. Staff reported feeling more confident and prepared, communication became proactive and professional, and team cohesion improved significantly. Supervisors and management noted stronger documentation, faster decision-making, and a noticeable shift in workplace culture toward safety and accountability.

What's My Motivation?

What motivates me most is seeing the shift in someone’s confidence — that moment when a trainee realizes they’re not just learning, they’re becoming someone their team can rely on. I’ve always believed that the right training doesn’t just prepare people for the job — it prepares them for leadership, for accountability, and for making a real difference in their workplace. That’s why I do this work, and why I keep refining it every day.
