He was a three-event (400, 1600, 3200-relay) qualifier for the PIAA State Track and Field Championships and medaled in the 3200 relay.
He was named to the Pittsburgh Post-Gazette Top 22.
At Harvard, Ken was a 3-year letterman as starting defensive back in football and was Honorable Mention All-American and All-New England in 1985. He was All-Ivy League in 1984 and 85.
He coached for several years at powerful Oceanside, California, the same high school attended by Junior Seau. Ken was a member of Mercer Athletic Hall of Fame's inaugural class.
