Sierra Canyon has won ten State Championships and eleven CIF-SS Championships along with seven additional CIF-SS Final appearances. In the 2017 fall season, the girls volleyball team won the school’s first-ever CIF State Championship and won back to back  CIF-SS Championships.  During the winter, the boys’ basketball team won the California Open Division Championship which is one of the most prestigious state championships in the country.  The Trailblazers compete in the Gold Coast League, where they have won 39 League titles.

The 2017-2018 school year was extremely successful as the Trailblazers won seven league titles (girls’ volleyball, boys’ basketball, girls’ soccer, lacrosse, golf, softball and beach volleyball.)
