The Baltimore City Board of School Commissioners announced Tuesday that Dr. Gregory Thorton will leave his post as schools CEO on Friday. But the move has been in the works for months.
Marnell Cooper, chairman of the school commissioner board, said the search was conducted quietly so the school system would not be distracted.
The board named Dr. Sonja Santelises, a vice president at The Education Trust - a non-profit that focuses on achievement gaps – in Washington, D.C., to replace Thornton. She is to take over July 1. Tammy Turner, the school system’s general counsel since 2006, will be acting CEO in the interim.
