Kellenberg Memorial High School offers a Catholic education in the Marianist tradition for young women and men. This “beautiful place to grow” educates minds and hearts into faith-filled disciples of Jesus Christ. This religious experience includes monthly School Masses, prayer services and retreat opportunities for all grade levels at Emmanuel Retreat House on the school property and Founder’s Hollow located in upstate New York. Many opportunities arise for students to engage in the Spiritual and Corporal Works of Mercy throughout the year including a Mission of Mercy to Lourdes, France during the summer before the senior year of high school. 

Individual student needs are met through three college preparatory programs: Honors, Academic I, and Academic II. In all three high school programs, students take four years of religion, English, history, mathematics, and science. Kellenberg Memorial offers students a choice of French, Latin, or Spanish. Students in the Academic II Program study a second English course and American Sign Language. All juniors take a full year SAT Prep course. Accelerated students in Mathematics have the opportunity to study Calculus or Statistics. Accelerated students in science have a choice to study Advanced Biology, Environmental Studies, or Health Sciences. All Kellenberg Memorial High School graduates are accepted into college. Qualified students may earn college credit in College Writing, English Literature, English Composition, American History II, Spanish, French, Latin, American Sign Language, Art Portfolio, Calculus, and Senior Religion. Kellenberg Memorial is affiliated with Farmingdale State College (SUNY), St. John’s University, and Molloy College for these college credit courses. Summer seminars in Chemistry, Physics, Calculus, and Statistics are also offered at no cost for those students interested in advancing their studies. 

In addition to all of the traditional sports and activities associated with the high school experience, Kellenberg Memorial offers students unique activities such as Bagpipe Club, Equestrian Club, and Culinary Club. Boys Hockey and Boys & Girls Crew will be added to our athletic offerings in the 2018-2019 school year. Our STEM cluster includes a wide range of co-curricular and extracurricular activities such as Mathematics Club, C.S.I. Club, Environmental Club, Health Sciences Club, Robotics Club, E.M.T. Training Program, Woodworking Club, Amateur Radio Club, Educational Television, Website and Social Media Club, and Lab Squad. Kellenberg Memorial also sponsors two Science Olympiad teams which have competed at the state level for many years. 

Priority of admission is given to baptized Roman Catholics. Kellenberg Memorial continues to feature a classical time-tested Marianist education while introducing cutting edge technology. Students engage the iPad as the primary source of textbooks, notebooks, and workbooks, as well as utilizing the device as a means of sharing work collaboratively in class and with their teachers. Harnessing the vast power of this digital resource, the students are meeting the traditional demands of a Catholic education with almost limitless resources. A $200 annual payment is made through a “lease to own” program so that the student graduates with the device that encapsulates his/her entire high school education.
