Brock's basketball programs (girl's and boy's) have been perennial state powers, including an unusual "double-double" in 2001-2002 and 2002-2003, when both the girl's and boy's teams won consecutive titles.
Brock has since won a state championship in every sport offered; baseball, softball, volleyball, cross country, track, golf, and tennis.
