Democratic State Sen. Dan Kotowski of Park Ridge said Tuesday he will resign from his position on October 5.
Kotowski, who has represented the state's 28th Senate District since 2007, said he is stepping down to become the president and CEO of the Chicago-based child advocacy group ChildServ.
"Since entering the Illinois Senate in 2007, I have made it my mission to represent my constituents by stopping the waste, mismanagement and corruption that stood in the way of solving problems that matter most to working families. During my service, my goal was to do all I could to end that culture and improve the quality of life for people in our state," Kotowski said in a statement.
"As rewarding as this work has been," he added, "there are many paths to choose in confronting our state's challenges, and I have a new opportunity to serve people in a very direct and meaningful way."
Kotowski's replacement will be selected by township Democratic Party leaders for the 28th District.
