In this episode of Rapid Fire Manufacturing, I sit down with Mark Hillenburg, co-founder of Collective Manufacturing Group.
Mark’s manufacturing journey started the hard way. A garage. Manual machines. A Bridgeport mill. Learning firsthand how difficult machining really is. Since then, he’s been a machinist, a CEO, and now a long-term owner focused on building manufacturing businesses meant to last decades, not flip in a few years.
We talk about:
Why culture matters more than spreadsheets
What real leadership looks like on the shop floor
How vulnerability builds trust in manufacturing teams
Succession, stewardship, and long-term thinking
The question every leader should ask: Would I want my kids to work here?
This is an honest conversation about people, leadership, and creating environments where manufacturing can thrive for generations.
