German International School Boston Expands with Long-Term Leases for Two Campuses

Boston, MAGerman International School Boston (GISB) is excited to announce the signing of long-term leases for two campuses, signaling a momentous leap forward in the school’s expansion and development trajectory. The first campus is the current 57 Holton Street location in Allston, a cornerstone of GISB’s educational history. The second location is situated at 46 Belmont Street in Watertown and represents an exciting new chapter for the educational institution.

These lease agreements signify a crucial milestone for GISB, providing the much-needed space to accommodate its growing student body and enhance its educational offerings. The Belmont Street campus will serve as the future hub for GISB’s preschool, kindergarten, and elementary school programs. This strategic move consolidates younger students into a single campus. Meanwhile, the existing Holton Street Campus will continue to be the primary site for GISB’s middle and high school students, ensuring a seamless educational journey for students as they progress through their later academic years. 

The GISB Board of Trustees anticipates that by summer 2025, the Belmont Street campus will be operational and ready to welcome preschool, kindergarten, and elementary school students. Both campuses are slated for renovations over the coming years to ensure state-of-the-art facilities that meet the evolving needs of GISB’s educational programs.

“We are thrilled about the opportunities these facilities offer, enabling us to provide a more comprehensive and enriching educational experience for our students.” remarked Tilman Kispersky, Chair of the Board of Trustees.

With these strategic lease agreements, GISB is poised to continue its legacy of academic excellence, fostering a nurturing environment for students to thrive academically, socially, and culturally.
