O'Connor was a camp counselor at the Hofstra University Basketball Camp, where he assisted with coaching, refereeing and supervision of camp attendees. He coached the Rising Stars (boys) and LI Xtreme (girls) AAU programs.
He started his coaching career in 1987 for his alma mater, Monsignor Scanlan High School in the Bronx, as an assistant men's varsity basketball coach. He played four years at Scanlan and then moved onto St. John's University where he played for two seasons with the junior varsity-club program.
O'Connor earned his bachelor's of science degree in Biology from St. John's University. In 1998 he received a master's of public administration from Marist College and he graduated from the FBI National Academy in 2003.
