About the Lab

Semper Golf Lab is an independent golf build and testing workshop focused on understanding how golf equipment performs through hands-on experimentation, craftsmanship, and modern technology.

The lab exists to study how materials, components, and build decisions—shafts, heads, weighting, and assembly—affect performance and feel. Rather than operating as a retail shop or commercial fitting studio, Semper Golf Lab functions as a small-scale workshop where equipment is built, tested, and refined with intention.

Founded by Brian Allen, an active-duty United States Marine and lifelong golf equipment enthusiast, the lab reflects a disciplined, methodical approach to learning. With a background in technology and problem-solving, Brian applies structured experimentation and real-world feedback to the building process, approaching golf equipment as systems to be measured, adjusted, and improved.

Work in the lab includes custom builds and rebuilds, component experimentation, and iterative testing informed by both performance data and on-course feedback. Learning is supported through mentorship from an experienced, licensed club builder to ensure proper technique and best practices.

Semper Golf Lab is an evolving workshop. The goal is not to claim expertise, but to earn it—through consistent building, testing, and refinement—while respecting the craft and the enjoyment of working with well-designed equipment.
