John C. Rebhan founded Warren Fabricating and Machining in 1967. He began with 4 employees in an 8,000 sq ft rented garage and evolved over the next fifty years to over 250 employees and 600,000 sq ft of manufacturing space. In the early 1980's he founded WARFAB Field and Erection which did the installation and erection for our mining products.
