"A Catholic School in the Marianist Tradition" Kellenberg Memorial High School is named in honor of Most Rev. Walter P. Kellenberg, founding Bishop of the Diocese of Rockville Centre. He had a particularly strong devotion to the Blessed Virgin Mary. Both in his preaching and his example, he sought to bring all under the protection of Our Lady. The Bishop was a strong supporter of Catholic education, as evidenced by his extensive building program for the school system of the diocese.

The school is owned and directed by the Society of Mary (Marianists), a religious order of priests and Brothers. The Marianists were founded in 1817 by Venerable William Joseph Chaminade to educate youth as a means of Christianize society.

In September, 1987, the Administration of Kellenberg Memorial High School announced the establishment of the Bro. Joseph C. Fox Latin School. The Latin School is named in honor of a Marianist brother, Bro. Joseph C. Fox, who taught for over fifty years in Catholic schools. This new division of KMHS will provide a qualitative Catholic education to students from the public schools in grades six through eight.

The school’s motto is “One Heart and One Mind”. Its colors are royal blue and gold; its emblem is the phoenix; and its nickname is The Firebirds.
