About the Inertium
A leadership coaching and organizational practice at the intersection of individual transformation and organizational performance.

The most persistent challenges leaders face aren't technical. They're human. And they're often invisible to the person creating them.
This became clear during a decade in aerospace engineering at Boeing — designing systems, solving complex problems, leading teams, developing people. The engineering was straightforward. The persistent problems were always about people and patterns. That's what I work on now.
I trained with iPEC, became an Energy Leadership Master Practitioner and earned my PCC through the ICF. I work with leaders across sectors — from individual contributors navigating difficult environments to C-suite executives at growth-stage companies and large organizations. The pattern is consistent: capable leaders shape conditions for the people around them in ways they can't fully see. When they can finally see it, things change.
Why this approach?
Every one of us creates conditions for the people around us — whether we’re conscious of it or not. A leader who operates from fear or protection doesn't just create a hard workplace. They send a contracted, depleted person home. Into their family. Into their community.
The inverse is equally true. When leaders create conditions where people are supported, and spend time in healthy systems, the impact ripples outward in ways that are hard to measure but impossible to miss.
Taking ownership of the space you create is one of the most important human responsibilities there is. That's what The Inertium is about.
Most interventions address one layer of the problem. They work with individual leaders, or run a team workshop, or restructure accountability. And then leaders wonder why it doesn't fully stick.
The Inertium works at all three layers simultaneously: individual factors (how leaders show up and growing as individuals), relational factors (how the team works together and addresses early signals), and systemic factors (the structures and clarity that either enable performance or constrain it). Each layer influences the others.
Addressing all three is what creates change that lasts.
