Under Kirner’s guidance, swimmers from the Charger program have qualified for the national meet a total of nine times in the past seven seasons. In 2009, one swimmer from all four classes - Anne Verhoef, Alicia LeDuc, Linda Okonkowski and Meredith Scott - each competed at the highest level of Division II swimming. It was Hillsdale’s most significant presence at the NCAA championships since it went to Division II status in 1998, and most signified the upward direction of the program. In 2011, Okonkowski secured the program's first Division II All-American honor in nine years under Kirner's guidance. Rachel Kurtz recieved the program's latest All-American honor in the 2013 season.
