Saddle River Day School completed a major campus expansion with the construction of the Dr. Kristen Walsh Hall of Science and Entrepreneurship, a 33,000-square-foot academic facility designed to elevate the school’s innovative programming and curriculum.

The Hall of Science and Entrepreneurship now serves as a state-of-the-art academic hub, purpose-built to support advanced instruction in science, technology, engineering, and entrepreneurship. The new building added 19 classrooms, four state-of-the-art science laboratories, and three specialty learning spaces. The facility supports advanced coursework in math and science, including physics, engineering, and Advanced Placement (AP) studies, expanding academic opportunities for students across the campus.

The project also included the relocation of the upper tennis courts, installation of artificial turf on the lower athletic field, and expanded parking capacity. The completed facility officially opened with a ribbon-cutting ceremony in September 2026.
