ABOUT ME

I'm Mark Dust. Combat veteran, PhD, and someone who spent years trying to think his way out of something that thinking couldn't fix.

I started in finance. Bachelor's degree from the University of Missouri-St. Louis, then a few years in the business world trying to figure out where I fit. Nothing stuck for long. I've got ADHD, which means I'm wired to chase what's interesting and move on when it isn't.

At 28, with a wife, two kids, and a third on the way, I enlisted in the Army. It was a childhood dream I'd been talked out of once and wasn't willing to let go of again. I went in as an infantryman and deployed to Iraq in 2005. I was a machine gunner on a Humvee. I was blown up by a roadside bomb. I came home with injuries and a nervous system that didn't know the war was over.

That's the moment from the Home Page, if you've already read it. The minivan, the pile of roadside trash, the swerve. That reaction didn't come from nowhere. It came from a brain that had learned to scan for threats and a body that still believed every one of them was real.

After a medical discharge in 2007, I stayed in Southern California and went back to work. I was managing community partnerships for a blood bank when I discovered the Drucker School of Management at Claremont Graduate University. Everyone above me in leadership had an MBA. I figured I should get one too.

The thing I didn't expect to find in business school.

I enrolled in the Executive MBA program expecting finance, strategy, and operations. What I didn't expect was a course called Executive Mind, taught by Dr. Jeremy Hunter, Associate Professor of Practice at the Drucker School and Founding Director of the Executive Mind Leadership Institute. I walked in convinced I was going to sit there cross-legged doing woo-woo hippie stuff. That's not what it was.

Instead, I learned mindfulness meditation, and it changed my life.

Not because it fixed me. Because it was the first time anyone had pointed me toward what was actually happening inside my body instead of asking me to think differently about it. At the time, I was doing everything the VA recommended. Medication. Group therapy. And I kept getting worse without understanding why.

Jeremy saw what I was dealing with and connected me with Elaine Miller-Karas, LCSW, Co-Founder of the Trauma Resource Institute. I trained in her Trauma Resiliency Model, the clinical intervention for nervous system stabilization. At the time, that was all that existed. But the clinical model couldn't reach everyone who needed it. Not every community has access to clinically trained providers, and not every person in crisis can wait for one. So Elaine and her team developed the Community Resiliency Model, a set of nervous system stabilization skills designed to be taught by and to people who aren't clinicians. I helped adapt those skills specifically for veteran and active duty military populations. I maintain certification as a CRM trainer to this day.

That was the pivot. I had been planning to become a business consultant. I was good at walking into organizations, finding the problems, and fixing them. But this was the problem I couldn't walk away from. So I stayed at Claremont and pursued a PhD in health promotion science with a concentration in neurocognitive sciences. I wanted to understand the brain, behavior, and how the stress response actually works at the physiological level.

Then I proved it works.

My dissertation was a controlled research study, but it wasn't conducted with trauma survivors or people diagnosed with PTSD. That's where most of the existing research had been done. I wanted to answer a different question: can these skills build physiological resilience in a healthy population before a traumatic or high-stress event, not just after one? The results said yes. Participants showed measurable physiological changes in how their bodies responded to stress, not because they were recovering from something, but because they were training for what was ahead.

That study is the foundation of everything I teach. It's why this work isn't limited to people who've experienced trauma. It's for anyone whose nervous system is carrying more than it was designed to handle, whether that comes from combat, a career in emergency medicine, or ten years of high-stakes decisions with no recovery between them.

Today I'm a full-time lecturer at California State University, Fullerton, where I teach stress management, determinants of health behavior, and public health administration courses in the undergraduate and Master of Public Health programs. The classroom keeps me sharp. Teaching the science to students who challenge it every semester is a different kind of pressure-testing than a peer review, and the work is better for it.

Bottom-up, not top-down.

Most approaches to stress and performance work top-down. They ask your brain to regulate your body. Reframe your thinking. Manage your mindset. Push through.

The problem is that when your nervous system is in full stress response, the rational part of your brain goes offline. You can't think your way out of a physiological state. That's not a discipline failure. It's biology.

My work starts with the body. It's grounded in the Community Resiliency Model, developed by the Trauma Resource Institute, and supported by decades of peer-reviewed research from scientists like Robert Sapolsky, Stephen Porges, Peter Levine, and Bessel van der Kolk. Their work mapped the biology of stress and trauma with precision.

My contribution is making those insights practical, trainable, and available to people who need them most.
