The Baltimore school board will announce Tuesday that Gregory E. Thornton, the superintendent of Milwaukee's public schools, will be the next CEO of the city school system, according to sources with knowledge of the situation.
Thornton, 59, who was in the running for Baltimore superintendent in 2007 when Andrés Alonso was hired, has roots in Philadelphia, where he was the No. 2 school official. He also has worked in the Montgomery County public school system in Maryland.
He has served as superintendent of the 78,000-student school system in Milwaukee since 2010 and recently signed a contract to stay on through mid-2016.
