Parrish attended East Stroudsburg South High School in East Stroudsburg, Pennsylvania where he played soccer for three years before joining the football team as a punter during his senior year. There, he earned All-Mountain Valley Conference and Pocono Record All-Area honors. He decided to join the football team after the schools' previous punter, Joseph Gaeta, who later played football at Temple University, became injured. Gaeta is credited with helping to convince Parrish to make the switch from soccer to football. He only had to punt three balls for the school's football coach before he was given the punting job for the rest of the season.
