The biggest challenges leaders face aren't technical—they're human. And they're often invisible.

This became evident during a decade in aerospace engineering at Boeing where I solved complex technical problems, designed systems, led teams, and developed leaders. The engineering was straightforward. The persistent problems were always about people and patterns.

That's why I became a coach. I trained with iPEC, earned my PCC through the ICF, and became an Energy Leadership Master Practitioner because I wanted to help leaders solve the challenges that engineering alone can't fix.

I've since worked with leaders across sectors—from individual contributors to C-suite executives—and the pattern is consistent: capable leaders get stuck in ways that don't serve them or their teams. They're moving fast, working hard, but often not headed where they truly want to go.

That's where The Inertium comes in.

The Inertium Vision

A world where leaders move with conscious intention.

Mission

We help leaders move from reactive patterns to conscious momentum through individual coaching, team alignment, and practical frameworks that address how people show up to their work, themselves, and each other.

“Working with The Inertium will shift your perspective and challenge you to dig deep to find the most effective way of working and leading. Ethan’s expertise in leadership development, effective communication, and strategic planning is unparalleled.
