Coach Billy Johnson has been most recently a member of the Milwaukee Brewers organization having signed a contract in February of 2009.

Johnson was previously signed on with the Windy City Thunderbolts which is an independent minor league club in Crestwood, IL. The ThunderBolts are part of independent baseball's Frontier League. As an independent club, the ThunderBolts have no affiliation with any major league team. Currently, former ThunderBolts are playing in the organization of two big league teams, the Florida Marlins and Kansas City Royals.

Independent leagues may not have affiliation with MLB but that does not stop players from advancing into different farm systems. The Frontier League has had 14 former players to reach the Majors and over 600 have signed into an affiliated team system since its conception in the early 1990s.

As a former University of Wisconsin-Whitewater catcher Johnson finished the 2008 Warhawk season with a .398 batting average, one of the best on the team. Johnson's fielding percentage was a respectable .974 with 10 errors in 50 games played.

Johnson was named to the first team of the Division III All-Midwest Regional Team this past year by the American Baseball Coaches Association. He was also named First Team All-WIAC this past spring.

Johnson has been part of Warhawk baseball history that has won the WIAC championship seven times in the past nine years. Johnson was on the roster in the 2005 season when Whitewater won the National Championship.

Coach Johnson handles all the catching and 1st base coaching duties, as well as assists with hitting.
