Mr. Neal Rackleff is the former U.S. Housing and Urban Development (HUD) Assistant Secretary for Community Planning and Development.

Before his work at HUD, Mr. Rackleff served as Director of the Housing and Community Development Department for the City of Houston where he oversaw the city’s community development projects and led the financing and production of over 7,800 multifamily housing units and assisted 1,700 single-family homeowners with reconstruction of hurricane damaged homes, financial assistance to low-income buyers and emergency home repairs.
