ST1 Precision was founded by Stone Hendrickson in 2021 in Phoenix, AZ. My journey in precision machining began at 14 years old, learning the trade hands-on. What started in my parents’ garage has grown into a full-fledged shop in Deer Valley, where we focus on delivering high-quality, precise solutions to our customers.

Unlike many shops that rely on older methods and resist new technology, at ST1 Precision, we embrace innovation. As a 20-year-old owner, I bring fresh energy, a deep understanding of work holding, tight tolerances, and customer needs, and a commitment to using the latest high-end machines to get the job done right.

We work with top medical technology companies and have earned a reputation for solving the toughest tight-tolerance parts. At ST1 Precision, we understand that when you need your parts, you need them yesterday. Tight deadlines, last-minute changes, or urgent projects don’t faze us—we don’t mind working late or all night to make sure your parts get delivered on time, every time.

We also value long-term partnerships. Our goal is to work with companies for years, even decades, providing solutions to challenging designs and tight tolerances while maintaining the highest standards of quality. Our Quality Management System ensures every part meets specifications and gives our customers confidence in every delivery.

From a small garage to a Deer Valley shop, ST1 Precision is built on innovation, precision, and relentless customer focus. We aren’t just a manufacturing shop—we are partners in problem-solving, committed to getting the job done right, on time, and every time.
