What The STEM Alliance does

The STEM Alliance is a 501(c)(3) nonprofit organization (EIN 46-0973552) headquartered in Larchmont, New York, that delivers STEM education enrichment and digital-inclusion programs to underserved communities across Westchester County with partnership extensions into NYC boroughs and statewide New York. The organization operates three integrated workstreams: STEM Education & Equity (after-school programs aligned to Next Generation Science Standards delivered free or at reduced cost at partner sites), Digital Equity (Digital Pathways and Connect Westchester initiatives that provide devices, internet access, and tech skills training through a Digital Navigator Corps, reaching 6,000+ clients since August 2020 with an independently validated $4.69 ROI per dollar invested), and Summer Enrichment (Co-Op Summer Enrichment, MOSAIC Innovation Camp, Shoreline Explorers After Care, and Family Tides). Core technology includes the STEM Quest mobile learning lab, a 33-foot ADA-compatible classroom launched in 2025 that serves 16 children at a time and travels to schools, camps, festivals, and community sites.

The organization generates revenue through a hybrid nonprofit model combining donations (individual, corporate, planned giving via the Power of Three Legacy Society), grants (Spectrum Digital Education, DASNY, Charter Communications, Alliant Credit Union Foundation), program fees (Mosaic at $500-$750/week, Shoreline Explorers at $56-$100), and event-driven fundraising (Summer Matters Gala raising $276,000 in March 2026 toward a $1.5M campaign; Play It Forward Tournament; STEM-tastic festival). Distribution is delivered through direct enrollment for fee-based programs, mobile deployment via STEM Quest, and partner-site delivery through a 70+ organization network including the Mamaroneck Union Free School District (anchor partner since 2017), Westchester County Government, and Westchester County Association. The most recent strategic milestones include the 2025 STEM Quest launch funded by a DASNY grant, statewide leadership of NYSDEN's 2025 Annual Conference, and continued scaling of the Connect Westchester digital-equity initiative.
