What Tower Hill School does

Tower Hill School is a private, nonprofit, college preparatory day school founded in 1919 and based at 2813 W. 17th Street in Wilmington, Delaware. It operates a single-campus PK-12 program structured into Lower School (Age 3-Grade 4), Middle School (Grades 5-8), and Upper School (Grades 9-12), serving an enrollment drawn primarily from Wilmington, Delaware and the broader Philadelphia metropolitan area. The school's core academic offering is supplemented by specialty programs including a Global Scholar Certificate, the Teaching and Learning Center, the Hillers Career Connect internship pipeline, 84 athletic state titles, and the Horizons Tower Hill tuition-free summer equity program launched in 2023 as the first Delaware Horizons National affiliate.

The business model is a hybrid of tuition and philanthropy: the primary revenue stream is recurring annual tuition for PK-12 instruction (pricing not publicly disclosed), supplemented by the Hiller Annual Fund (fiscal year July 1 - June 30), an eight-tier Giving Society ladder ranging from the Head of School's Circle ($1,000-$1,918) up to the Cornerstone Circle ($50,000+), the Forever Green Society for planned giving, an extensive summer programs ecosystem (Day Camps, Academic Camps, Sports Camps, Enrichment Camps, Camp Bundles, and the Summer Institute priced $215-$750 per program), and a school store selling branded merchandise through physical and Square-based online storefronts. $4.1 million in financial aid is distributed annually to support student access.

Go-to-market is direct-to-consumer with no reseller or agent channel: families inquire online, attend open houses and campus tours, apply through the school's admission process, and enter a continuous PK-12 enrollment cycle. The school's reputation (Niche #1 in Delaware, #10 in Philadelphia, top 50 national day schools) and word-of-mouth from a 3,400+ global alumni network drive demand. Distribution is anchored at the single Wilmington campus, with auxiliary programs (summer camps, retail) extended to both enrolled and external community members. The institution employs 101-250 staff, operates under a Board of Trustees governance model with no parent company or private equity ownership, and reports to a Delaware-registered 501(c)(3) nonprofit structure.
