Machine Shop Mastery 103. A Father's Legacy, a Daughter's Vision: Carrying a Family Machine Shop Forward
Taking over a family machine shop is never just a business decision. It's personal. In this episode of Machine Shop Mastery, I sit down with Nubia Perez of Gretna Machine Shop to talk about what it really means to carry a founder's legacy forward while finding the courage to lead in your own way.
Nubia shares the origin story of Gretna Machine Shop, founded by her father after immigrating to the U.S. with little more than a suitcase and a trade. What began in a small garage evolved into a respected Houston-based precision machining company serving oil and gas, aerospace, and defense. But the journey wasn't linear, and it wasn't easy.
After her father's health declined and he passed away shortly after Nubia joined the business, she was left to navigate leadership without the long runway many second-generation owners get. For nearly a decade, she focused on administration, growth initiatives, and diversification, without fully stepping into the role of CEO. Those years, which she candidly refers to as "the dark years," revealed a hard truth: the business didn't just need management, it needed vision.
This conversation explores Nubia's transformation from reluctant successor to confident leader. We talk about imposter syndrome, EOS, values-based leadership, mindful manufacturing, and how culture changes when the stress comes from the work instead of the people. It's an honest, human story about growth, grief, responsibility, and learning to lead as yourself — not as a replica of the generation before you.
