Most of the fathers on his block were coal miners or worked in Springfield's factories. His father, William Cellini Sr., was a coal miner and amateur boxer from the age of 12 until he was 22 when he became a 37-year member of the Springfield Police Department working the 11pm to 7am shift for 20 of those years.
