Loss of a visionary

For a man who walked in humility, Chet Cole seemed larger than life.

Cole, the passion, drive and face of the Key Training Center for 46 years, died Sunday morning after suffering an apparent stroke two days earlier. He was 72.

Through years of tireless devotion to what he called “these people,” Cole’s Key Training Center changed the lives of thousands of the developmentally disabled and their families.
