The new school quickly began to establish its identity by selecting its school colors, selecting green and silver, signifying hope and sterling worth. And, in keeping its connection with Mission's historical tradition, the student body chose “Pioneers” as the school name. In addition, many clubs and activities were organized during these first years: Student Council, Sodality, GAA, Glee club, Orchestra and Drama clubs. The school was alive with many sports’ activities. The boys were able to join football, basketball, track, soccer, golf, bowling and tennis teams. The girls participated in volleyball, basketball, and tennis. Intramural sports, Play Day and Field Day became, and still are, annual events. Dances, rallies, drama and musicals rounded out the activity schedule.
