After retiring from the NFL, Treadwell attended law school at the University of Denver and participated in the campaign to pass a ballot measure to fund the replacement for Mile High Stadium which ultimately became known as Invesco Field at Mile High. That led to a new career in the media.[1] He became a sports talk show host at Denver-based Clear Channel corporation stations KOA and KTLK before moving to Denver's KDVR-TV (Fox 31) as sports director and anchor from 2000 to 2004. He reportedly left the station to "pursue business interests in a land development company."[2] He now works for Biltmore Development and is chairman of the board of directors of the St. Anthony North Health Foundation, affiliated with St. Anthony North Hospital in Westminster, Co., a suburb just north of Denver.[3]
