Three Hundredths of a Second That Changed Everything

Kellie Mix | Burnout & Resilience Coach and Expert

Kellie Mix knows what it feels like to push through, grind it out, and put everyone else’s needs before your own because that’s how she was raised and trained. As a military veteran, athlete, coach, and mom, Kellie spent years ignoring the signs of burnout, thinking it was just part of being “tough enough.”

Her turning point came when she left the military and asked herself hard questions: What do I want my life to feel like? What are my values? With the support of a coach, she began to reconnect with herself and realized how deeply burnout had taken root.

Today, Kellie is a certified resilience and burnout coach who helps high-performing women, military spouses, and athletes recognize the signs of burnout and learn to build lasting resilience. She draws from evidence-based frameworks and her lived experience to offer practical tools, deep empathy, and a clear path forward.

A former elite swimmer who missed the Olympic Trials by 0.03 seconds, Kellie understands the heartbreak of unmet goals and the power of rewriting your story. Years later, she did just that by returning to the sport she loved on her terms, competing at the World Military Games in China and rediscovering her joy.

Kellie’s work is grounded in her five core values—live, love, learn, lead, and serve—and her mission is simple: to help others reclaim their energy, time, and sense of self.

Kellie is an Executive Coach, Burnout & Resilience Expert, and co-facilitator of The Edge of Resilience program at Sixth Wing. She also serves as a leadership advisor and Chief of Staff, bringing a rare blend of lived experience and professional expertise to her work. Sixth Wing helps leaders and teams navigate complexity with clarity, resilience, and purpose, improving performance, reducing burnout, and building sustainable, high-impact leadership.

The Day I Almost Walked Away

John Previtera | Burnout & Resilience Coach and Expert

After nearly 30 years in the Navy, of which 21 were spent as a Navy SEAL, a career that demanded constant readiness, peak performance, and unshakable composure, John Previtera found himself in a place no amount of training had prepared him for: complete burnout.

It didn’t happen on the battlefield. It crept in after retirement, when he was supposed to finally exhale. After decades of leadership under extreme pressure, operational tempo had become his identity. And in its absence? Silence. Disconnection. Exhaustion. The kind that doesn’t go away with a good night’s sleep.

Burnout wasn’t supposed to happen to someone like him. But it did.

John’s defining moment wasn’t in a war zone; it was confronting the cost of never slowing down, always putting mission over self, and building a life so committed to service that there was no room left for recovery.

That moment, raw, humbling, and deeply human, lit a new path, not away from leadership but toward redefining it.

Today, John is a burnout and resilience expert, not because of a credential (though he has those, too), but because he lived it. He knows the silent toll it takes, especially on high performers, leaders, veterans, and those who carry the weight for everyone else.

His work is grounded in compassion, clarity, and credibility. He’s not here to offer hacks. He’s here to help people rewrite their stories, to build resilience that works in the real world, not just in theory.

He pairs his decades of elite military leadership and executive coaching with a human-centered approach that resonates in boardrooms and briefing rooms alike. John is recognized for his thoughtful facilitation, powerful storytelling, and ability to weave wisdom into conversations in ways that leave people pondering long after the session ends.

Burnout didn’t define him. But it did reshape him.

And that’s the message he conveys to teams, leaders, and individuals ready to do the work—to keep going and live and lead better.

John is an Executive Coach, Leadership Development Advisor, Burnout & Resilience Expert, and co-facilitator of The Edge of Resilience program at Sixth Wing. He also mentors Chiefs of Staff, drawing on his years as a Navy SEAL and his own lived experience navigating burnout in high-stakes environments. At Sixth Wing, John brings a thoughtful, authentic approach that helps leaders and teams build resilience, strengthen performance, and lead with clarity.
