Stephen Levin grew up in Plainfield, New Jersey and came to Brooklyn to work as a community organizer after he graduated from Brown University. Stephen started his career in community organizing by simultaneously running a Lead Safe House program and an Anti-Predatory lending program, both based in Bushwick, Brooklyn. The Lead Safe House program helped to relocate families of lead-poisoned children out of hazardous apartments. Stephen also used this program to work with homeowners to effectively and efficiently remediate lead contamination.

As director of the Anti-Predatory lending program, Stephen organized homeowners throughout the community through grass-roots outreach and community workshops about the dangers of subprime mortgages. Working with the City, local elected officials, and advocacy groups, Stephen was able to galvanize the community against the unscrupulous lending practices that were decimating the neighborhood with foreclosures.

In 2006, Stephen became Chief of Staff to Assemblymember Vito Lopez, Chairman of the Assembly Housing Committee (D-Williamsburg). As Chief of Staff and a dedicated advocate for affordable housing, Stephen secured funding of over 1,000 units of affordable housing.

In November 2009, Stephen was elected to represent the 33rd District of Brooklyn, which covers Greenpoint, Williamsburg, Park Slope, Boerum Hill, Brooklyn Heights, DUMBO, and Vinegar Hill.
