The Fresno State chapter of the Sigma Chi fraternity presented a $25,000 check April 8 to Children’s Hospital Central California. The funds collected were a result of the chapter’s annual philanthropy, “Derby Days,” when Fresno State sororities compete in wall painting, skits and a derby hunt. This year’s donation marks $100,000 in total funds raised by Sigma Chi for the hospital.   INFO: Jared Bertoni, Sigma Chi public relations chairman, at jaredbertoni@mail.fresnostate.edu
