The standard behind the parts.
GS3 was built on a simple idea: in manufacturing, performance is everything.
For more than 15 years, we've operated inside the automotive supply chain — one of the most demanding manufacturing environments in the world. Tolerances are tight. Timelines are unforgiving. Launch windows don't come twice. That environment didn't just shape how we work — it set the standard we bring to every customer, in every industry we serve.
When you've held automotive-grade quality under production pressure, you're prepared for anything.
That's the capability GS3 carries into aerospace, consumer products, clean energy, medical, and industrial applications — disciplined process control, rigorous quality systems, and a team that performs under production pressure.
We invest in that expertise internally — developing people, building capability in-house, and showing up with urgency and accountability. We don't just make parts. We stabilize programs, reduce risk, and build production pathways our customers can rely on.
As manufacturing evolves toward electrification, advanced automation, and new materials, GS3 is evolving with it — bringing the same standards that earned our reputation in automotive to the industries defining what's next.
The industries change.
The standard doesn't.
The people behind the standard.
Lisa Lunsford doesn't come from the business side of manufacturing. She comes from the floor of it.
Her career began with a decade as a research and development engineer in Ford's Plastic Products Division — now Visteon — where she developed the technical instincts and process discipline that still define how GS3 operates. Before founding GS3, she built iThinc, a custom software company specializing in supply chain applications, proving early that she understood not just how parts are made, but how the systems around them work.
That combination — engineering depth, entrepreneurial range, and supply chain fluency — is what she brought to GS3, and what has driven its growth into one of Michigan's most recognized woman-owned manufacturing companies.
The recognition has followed the performance.

Lisa isn't just recognized in the industry — she's shaping it. The relationships, perspective, and access she brings to GS3 are a competitive advantage for every program we run.
Her civic commitment runs equally deep. Lisa serves as Board Chair of MICHauto and ProsperUS Detroit, and as a board member of The Children's Center — Detroit. She builds outside the plant the same way she builds inside it: with purpose, accountability, and a long view.
Robert Gruschow co-founded GS3 and serves as its President, bringing decades of integrated supply chain leadership that spans manufacturing, logistics, packaging, and distribution. Alongside GS3, he is President of Deshler Group and of Feblo International, a custom packaging, warehousing, and distribution company, and a managing member of Global Transportation Management, a global transportation and logistics firm. Few leaders see the full path from raw material to delivered product as completely as he does.
Across his career, Robert has built lasting partnerships and engineered practical solutions for manufacturers, suppliers, and customers across industries. As a board member of Deshler Group since 2004, he has led the acquisition and integration of complementary capabilities — manufacturing, assembly, transportation, packaging, and information technology — assembling the kind of end-to-end capacity that strengthens every program GS3 runs. He holds a bachelor's degree from Albion College and a master's degree from the University of California, Santa Cruz. He also studied architecture at the Rhode Island School of Design and semiconductor manufacturing at Central New Mexico Community College. He lives in Michigan.
Nick Stephey serves as General Manager of GS3, overseeing all plant operations — production, engineering, quality, safety, and delivery — across prototyping through high-volume production. With 25+ years of manufacturing leadership experience, including a decade at GS3, Nick brings deep operational expertise to every program the plant runs.
A Six Sigma Black Belt and U.S. patent holder, Nick is recognized for his command of production engineering, precision metal forming, and CNC operations. Beyond his technical leadership, Nick is personally committed to growing American manufacturing and the workforce that powers it — a mission shaped by his own experience with employment displacement earlier in his career.
