An important part of the high school experience is the participation with fellow students and faculty members in activities of personal interest and development. Kellenberg Memorial High School offers a full range of sports and activities which stimulate and develop the interests of each student. Co-curricular activities allow the student to pursue interests and talents related to the course of study. Extracurricular activities give the student a chance to serve and to pursue interests not directly related to their studies. Athletics, on both the intramural and interscholastic levels, combine physical development and exercise with competition and enjoyment.
