From Garage Shop to Industrial Production Facility

GPR building

GPR was founded in 1979 with 500 dollars in the garage of George G. Verhoest, the father of GPR founding members George, Paul, and Richard. The company’s original goal was to build high-performance steering boxes for the racing community – an industry in which the owners were already heavily involved.

The company found success and soon began to seek new manufacturing opportunities to fill the shop’s open spindle time. Through word of mouth GPR quickly began to succeed in new industries, which led to taking on an expanded employee base as well as a larger production space.

Spearheading the Semiconductor Equipment Manufacturing Space

In 1984, GPR was presented an opportunity to partner with the leading semiconductor equipment manufacturer on a custom vacuum chamber for the emerging semiconductor industry. GPR capitalized upon this success to springboard into the industry, quickly growing into one of the nation’s top manufacturers of vacuum chambers and process components.

Looking to the future, GPR continues to grow with eyes on new technology and increased space. GPR strives for cost reduction while decreasing lead times through optimized machining and inspection processes spearheaded via our Quality Management System.
