He attended Tell City High School, Class of 61’ in Tell City, Indiana. Clark was a gifted athlete in both football and basketball, playing for the legendary Hall of Fame Coach, Gunner Wyman and was a state qualifier that year with the Tell City Marksmen.
Upon graduating, Clark was accepted to Purdue University, entering into their demanding Mechanical Engineering program and was a charter member of the Phi Sigma Kappa fraternity in which he remained active throughout his life.
After graduating in 1965, he was offered an opportunity with Cummins Engine Company where he thrived and eventually became the General Manager of the Worldwide Bus Business. During his tenure at Cummins, Clark was a prominent figure in the development and roll-out of high-performance engines for the industry. He played a key role in advocating for alternatively fueled engines, helping to modernize transit fleets across North America.
