This invention has been widely credited for the boom in affordable housing, productivity increases and improved building durability throughout the world. He went on to be one of the founders and the first president of the Truss Plate Institute (TPI) and built Automated Building Components, Inc. with headquarters in Miami, Florida into a publicly traded company on the American Stock Exchange and the worldwide industry leader in truss plate manufacturing, truss manufacturing, truss press/saw machinery and computerized engineering and design.
