"A Catholic School in the Marianist Tradition" Kellenberg Memorial High School is named in honor of Most Rev. Walter P. Joseph C. Fox Latin School.

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

With the conclusion of our school year, we are also privileged to celebrate the retirements of:

Alice Accardi, a founding member of the Kellenberg Memorial faculty, who devoted 40 years to teaching mathematics with excellence and care.

Albert “Stretch” Williams, a 21-year staple of the maintenance department and proud supporter of Firebird athletics, whose dedication to our campus helped make everyone feel right at home.

Maryann Graziano, who inspired generations of students over her 21 years in the Science Department, leaving a lasting impact through her passion for teaching.

Lisa Haller, who served 22 years as both teacher and administrator, and also as a founding member of the faculty at St. Martin de Porres Marianist School.

Together, they represent more than a century of service to Marianist education, shaping minds and forming hearts. We extend our deepest gratitude for their unwavering commitment and wish them every blessing in this next chapter of their lives.

Today, we give thanks for all fathers, grandfathers, godfathers, and father figures whose love, sacrifice, and guidance reflect the faithful example of St. Joseph.

As the guardian of the Holy Family, St. Joseph led with humility, courage, and unwavering trust in God. May his example inspire all fathers to be steadfast in faith, devoted to their families, and strong in their vocation.

Consecrate the fiftieth year and proclaim liberty throughout the land to all its inhabitants." — Leviticus 25:10

On Juneteenth, we celebrate the triumph of freedom and honor the incredible legacy of Black Catholics who fought for dignity and education in our country and our Church.

Today we remember figures like Servant of God Mother Mary Lange, who founded the first Catholic religious order for women of color and opened schools against all odds. Her courage reminds us what it means to stand up for justice.

Progress never stops at Kellenberg Memorial.

Last summer, the St. Carlo Acutis Technology Center came to life, sparking a year of innovation, collaboration, and hands-on learning. Now the hub of technology on campus, it inspires students to explore and shape the world around them.

As another summer approaches, the question isn’t whether progress will continue, it’s where it will take us next!
