Head Coach Pete Johnson began his coaching career by assisting local legend Dick Peper in 1993.  He took the helm after Coach Peper's sudden death in the middle of the 1998 season. Pete has led the Pirates to eleven conference championships with twelve regional titles, four sectional runner-up finishes, and trips to state in 1998 and 2011. He oversees the youth baseball program during the summers, coaching junior high (since 1993) and other levels through the years. A 1986 graduate, Pete played shortstop for Grantsburg and was a four-year letter winner, three-year batting champ, two-year All-Conference player, and member of the 1984 state tournament team. He is grateful to be a product of "Peper Ball," and appreciates his role in the strong Grantsburg Baseball tradition. Pete graduated from UW-Eau Claire in 1991 and taught in the Grantsburg district for 11 years, then worked at Northwestern Electric Company for 17 years before returning to the school district in 2021.
