What unites us is much greater than what divides us.
-Pope St. John XXIII

At St. John XXIII we believe that the formation of our students takes place not only in the classroom, but also through participation in extracurricular and co-curricular activities. 

Students at St. John XXIII have the opportunity to join many clubs and participate in a variety of activities that will enhance their high school experience.
