Leadership & Staff

John O'Callaghan

President & CEO

John O’Callaghan serves as the President and CEO of Atlanta Neighborhood Development Partnership (ANDP) where he leads the organization’s programs to develop, finance, and advocate for affordable housing at scale that promotes racial equity and healthy communities where families thrive.

Established in 1991, ANDP was created to address the diminishing supply of affordable housing in the Metropolitan Atlanta region as well as to help reclaim declining neighborhoods in its core. 

ANDP has prioritized addressing the 30 percent homeownership gap between Black and While households, which is a root cause of the wealth gap in America. ANDP has effectively utilized governmental, nonprofit, and for-profit partnerships to scale its impact.  In the last five years, the organization has more than doubled its output in single-family homeownership, rental and multifamily development. ANDP is one of the nation’s largest nonprofit developers of affordable homes.

ANDP’s CDFI lending arm has developed an innovative partnership with Philadelphia-based The Reinvestment Fund (TRF) to better deploy community development-focused 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 spent nearly a decade in local government, serving as a Fulton County Commissioner, Atlanta City Councilmember, and Director of Intergovernmental Affairs under Atlanta Mayor Maynard Jackson. Prior to joining ANDP, John spent 11 years as a Regional Public Affairs Director at Fannie Mae where he helped create and lead Fannie Mae’s housing and community development outreach network for an 11-state region. His early career was spent in fundraising positions with the American Red Cross and United Way of Metropolitan Atlanta. 

John’s board appointments include Truist Bank, Regions Bank, IBERIABANK, Housing Partnership Network, National Housing Conference, Framework, and Atlanta Metropolitan College Foundation.  He is actively engaged in national and local policy work to address racial equity and the wealth gap through better utilization of government funding to support affordable homeownership.


John is currently leading ANDP’s “Closing the Gap” unit plan and capital campaign to create and preserve 2,000 units of affordable housing by 2025 to reduce the homeownership gap, affordability gap and ultimately the wealth gap between Black and white households.

John is a native of Atlanta and a graduate of Georgia Tech.  He and his wife Jennifer have four children.
