Skip Wagner, who is credited with boosting attendance and revenue for the Houston Livestock Show and Rodeo as its president and chief executive officer, is leaving the venerable show.

Officials announced Wednesday that Wagner has accepted a position as the president and CEO of the 12th Man Foundation at Texas A&M University.

Wagner joined the Houston Livestock Show and Rodeo in 1992 as assistant to the general manager, primarily focused on grounds entertainment, operations and fundraising aspects of the event, leaving in 2000. After a three-year stint as president and general manager of the Oklahoma State Fair in Oklahoma City, Wagner returned to the Houston Livestock Show and Rodeo in 2004, and was elected as president and CEO in 2005.

Also during Wagner’s tenure, the volunteer base grew from 17,000 to more than 28,000.

Current chief operating officer, Leroy Shafer, will serve as interim president and chief executive officer.
