At the heart of our company stands a legacy forged by Rae Crowther — a passionate lineman, championship player, and pioneering coach. A former star with the Frankford Yellow Jackets, the team that would evolve into the Philadelphia Eagles, Rae brought his relentless drive and innovation to coaching at powerhouse programs like Drexel, Harvard, and the University of Pennsylvania. But his greatest impact came off the field — in the development of training equipment that would revolutionize the game.
