Philosophy & Approach

"Everything is a Negotiation"

Throughout diverse professional experiences—from military service to corrections, crisis negotiation to corporate sales—the consistent thread has been this core belief: everything is a negotiation. Whether managing a crisis, closing a sale, or navigating a high-conflict relationship, the fundamental skills remain the same: understanding human motivation, maintaining composure under pressure, and strategically guiding interactions toward better outcomes.

This interdisciplinary background creates a unique coaching approach that combines:

  • Tactical law enforcement expertise in managing dangerous personalities

  • Crisis negotiation training in high-stakes communication

  • Therapeutic understanding of trauma and emotional patterns

  • Strategic business acumen from corporate environments

  • Service-oriented leadership from military experience

The result is coaching that is pragmatic, strategic, and deeply informed by real-world experience with the most challenging personalities anyone could face.

Why These Credentials Matter for High-Conflict Coaching

Unlike coaches who approach this work solely from personal experience as survivors, my credentials represent professional training and career-long engagement with high-conflict, low-empathy personalities in some of the most challenging environments possible:

Corrections facilities - Daily interaction with antisocial personalities
Crisis negotiation - Life-or-death stakes with unstable individuals
Military service - Leadership under pressure and team welfare
Corporate sales - High-stakes negotiation with sophisticated opponents

This is not theory. This is tested, proven expertise in dealing with the exact personalities that make my clients' lives difficult—and teaching them how to do the same.

My Story

I didn’t plan on becoming a high-conflict coach—it grew naturally out of my life and career. I began in the U.S. Coast Guard, serving in roles that meant taking care of others and keeping order in uncertain conditions. Later, as a corrections officer, I worked daily with people for whom empathy was absent. I received commendations for saving lives and supporting colleagues, and I trained with the Crisis Negotiation Team, learning how to stay calm and clear in the most chaotic situations.

When I moved into the tech industry, I thought I’d left that world behind. But high-conflict personalities show up everywhere—in offices, partnerships, and families. I saw the same draining patterns and once again found myself guiding others through them.

Today, I’m a Certified Master High-Conflict Negotiations Coach, trained in Rebecca Zung’s SLAY method and experienced in teaching and co-hosting workshops. What sets my approach apart is the blend of formal training and decades of lived experience managing conflict in real time.

My mission is simple: to help you move from disorder to clarity, reclaim control from high-conflict personalities, and chart a course back to peace—where you, not the conflict, are at the center of your life.
