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 and People leadership roles at 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 that kind of upheaval in my own life — a prostate cancer diagnosis, a recurrence, and the depression that followed. It dismantled a lot of what I thought defined me, and it taught me something I didn’t expect: the same instincts I’d spent decades using to steady organizations through change were exactly what I needed to rebuild.

That’s what The Mettle is built on — awareness first, then resilience, then action. I’ve tested every tool on myself before bringing it to anyone else.

Whether I’m working with an executive, a leadership team navigating organizational change, or an individual rebuilding after a major life shift, I slow things down. We make sense of what’s shifted, rebuild trust in good judgment, and move forward with purpose — through honest conversation, thoughtful structure, and a steady partnership.
