About Jeffrey Zwillenberg
I’m an MBA-educated executive with 15+ years leading nonprofits at the intersection of mission, strategy, and growth. I’ve successfully scaled teams, exceeded fundraising goals, built cross-functional operations, and led organizational transformation—from grassroots education efforts to statewide social service agencies.My leadership style is people-first and purpose-driven. I’ve raised millions in private revenue, launched legacy giving programs, led major CRM overhauls, and served as a trusted executive advisor on finance, HR, and IT. I thrive in dynamic environments where strategic clarity and team culture are critical.I’m currently exploring leadership or consulting opportunities where I can help mission-aligned organizations increase their impact, build resilient systems, and empower their people.
