Miss Ohio USA

Following her America's Next Top Model loss, Stewart entered the Miss Ohio USA 2004 competition held in late 2003. She was first runner-up to Lauren Kelsey Hall in that pageant. Stewart later competed again for the Miss Ohio USA 2006 crown in 2005, but Shannon Stewart only made the semi-finals. The title was won by Stacy Offenberger.

Stewart continued to model, and signed with Elite Models in Chicago and Major Model Management.
