Simpson Alloy Services was founded in 1992 and incorporated in 1997. In addition to SAS, there is Simpson Farms, LLC, and Simpson Agri Trucking – two of our varying operating entities. In 2008, Coy Stepro became the General Manager of Simpson Alloy Services and eventually expanded into the aerospace industry by cultivating Simpson Aerospace Services. We’ve expanded substantially since our humble beginnings including the construction of our 21,000 sq. ft. shop facility that was completed in 2015. The new facility paved the way for growth in ground support equipment while allowing us to better serve our customers in the heat treat industry.
