Born in Cleveland, Ohio on March 29, 1957, Doug Shilliday spent his formative years in the Cleveland area, and moved to Poland, Ohio in September of 1970.
He started to swim competitively in 1965 after suffering an accident that cut off his heal. He was confined to crutches for a three month period, was ordered to swim as part of his rehabilitation. What started out as a remedy for an ailment quickly turned into a hobby and that turned into a hobby and that turned into a burning desire to compete, which has earned him a place in the eighth class of Hall of Fame inductees at the Youngstown State University.

It's a record that will never be broken at Youngstown State.
