Happy National Professional Engineers (PE) Day! The first PE license was issued to Charles Bellamy in Wyoming on August 8, 1907. The PE license is the highest recognition and a symbol of achievement and quality assurance for engineers. Spirit is happy to recognize our PEs: Clem Cros, Keegan Conley, James Keck, and Johnny Vermillion for all their hard work! Collectively, they are registered PEs in Colorado, Kansas, Louisiana, New Mexico, Oklahoma, Texas, and Wyoming.
