| David Weinstein has resigned as chairman of the Chicagoland Entrepreneurial Center, citing personal reasons, according to a statement from the Chicagoland Chamber of Commerce released Friday.

John Roberson, who was most recently president of Target Group Inc., has been named executive vice president of the center. He replaces Jason Felger, who is joining Redbox as a member of the strategy and business development team.

A replacement for Weinstein has not been named. Boards of both the chamber and the center must approve the successor.
