Following graduate school he began his teaching career in Mechanical Engineering at SDSU, retiring as a full professor. After retiring, he moved to Tucson, Arizona to be close to his son and grandsons. Kenneth was a kind, gentle man with a wonderful, unending sense of humor and teasing nature. Kenneth loved teaching and he was well loved by his students. For over two decades, he served as the faculty advisor for the SDSU American Society of Mechanical Engineers student chapter. He loved pheasant hunting which was a passion he shared with his son and grandsons. He took pride in the homes he built and he was a tinkerer with anything mechanical, building motorbikes and restoring cars and a Jeep. He had an unwavering Christian faith and has returned home to be with those he loved.
