Trusted Precision Machining in Huntington Beach Since 1981
For over four decades, the Geisert Family has been a trusted name in precision machining and custom fabrication services in Huntington Beach, California. Originally founded in 1981, our machine shop has built a reputation for quality craftsmanship, attention to detail, and reliable service.

In 2000, Brian Geisert proudly took over the family business from his father, carrying the same passion for machining and commitment to excellence. Today, Sertec Precision Machining continues to serve clients across Southern California and beyond, specializing in CNC machining, prototype development, small-batch manufacturing, and more.

When he’s not in the shop, Brian enjoys the beach, time with family, classic cars, and motorcycles—interests that naturally led to the next evolution of the Sertec brand: Sertec Performance.
