President & CEO

Since 2006, John O’Callaghan has served as the President and CEO of Atlanta Neighborhood Development Partnership (ANDP) where he leads the organization’s policy, lending, and housing development programs aimed at ensuring mixed income housing opportunity near job centers across metro Atlanta.

ANDP is currently focused on addressing the region’s foreclosure crisis and the lasting impact of negative equity on neighborhoods. ANDP is one of the nation’s largest nonprofit redevelopers of vacant foreclosed homes – impacting 432 single-family units and 88 multifamily units since 2008.

Under John’s leadership, ANDP’s CDFI lending arm has developed an innovative partnership with Philadelphia-based Reinvestment Fund to better deploy community development capital.  In addition, ANDP helped to spearhead Piece by Piece, a regional foreclosure response initiative comprised of more than 150 public and private partners.  Piece by Piece was recognized by the National Housing Conference with a 2015 Housing Visionary Award.

John’s nonprofit experience includes time with United Way and The American Red Cross. His governmental background includes Mayoral appointed positions with the City of Atlanta and elected service on the Fulton County Board of Commissioners and Atlanta City Council. He also spent 11 years in regional public affairs with Fannie Mae.

John currently serves on: Atlanta Regional Commission’s Environmental Land Use Committee, Atlanta Metropolitan College Foundation Board of Directors, Housing Partnership Network Board of Directors, Framework Board of Directors, and the National Housing Conference Board of Governors. He is playing active roles in local and national networks focused on stabilizing communities devastated by foreclosure.
