Girls Preparatory School announced Monday that Jeff Gaither, a coach and English teacher at the school for 20 years, will serve as interim athletic director through June 15.
Gaither takes over for Stacey Hill, who resigned after being arrested in a prostitution sting last week in Dalton, Ga.
A national search is underway for a full-time athletic director, according to a GPS release.
Most known for his work with the cross country and track Bruisers at the high school and middle school levels, Gaither headed the 2002 region-runner-up basketball varsity. His track teams won state championships in 2005 through 2007, and he has a cross country state title as well.
He has coached 48 individual individual state track and cross country champions, the GPS release said.
Gaither is a four-time Times Free Press girls' track and field coach of the year and was the cross country honoree this past fall. He has finished the Boston Marathon twice.
He earned a bachelor's degree in English from Georgia and served the university as men's and women's head coach in cross country and an assistant coach in track before coming to Chattanooga.
