Andrew Mainwaring — The Mettle Coach

I help people and organizations navigate the kind of change that goes deeper than process.

For over twenty years, I helped leaders and organizations navigate serious change — mergers, acquisitions, and transitions that tested everyone involved.

Then life handed me my own version. Now I coach leaders and individuals through the moments that demand more than a framework.

My Background

I spent over 20 years in senior HR Business Partnering and leadership roles at companies like AOL, Yahoo, and Verizon Media — leading teams through mergers, acquisitions, and the kind of sustained change that tests everyone involved. From London to Los Angeles, I built a career around helping leaders and organizations find their footing when the ground shifts.

In 2022, I faced the biggest challenge of my life — a prostate cancer diagnosis. What followed wasn’t just a health crisis. Grief, a recurrence, and a period of deep depression dismantled everything I thought defined me.

But somewhere in that unraveling, I discovered something I didn’t expect: the instincts I’d spent decades developing to help organizations through change were the same ones I needed to rebuild my own life.

Awareness first. Then resilience. Then action. I didn’t just study how people navigate change — I pressure-tested every tool on myself first. That’s what The Mettle is about. I went from breakdown to breakthrough, and now I help others find their own way through.

Whether I’m working with an individual rebuilding after a major life shift or a leadership team navigating organizational change, I slow things down. We make sense of what’s shifted, rebuild trust in good judgment, and move forward with purpose. No pep talks. No generic frameworks. Just honest conversation, thoughtful structure, and a steady partnership for people navigating real change.
