The U.S. Department of Housing and Urban Development under the Obama administration is equipped with an impressive list of housing experts at the top. But with the housing crisis thats continued to grip the country, success wont come easy for anyone, particularly for the principal staff at HUD—an agency that has gone from “sitting at the kids’ table,” Sen. Robert Menendez (D-NJ) told Affordable Housing Finance in September 2009, to an agency that now sets major policy initiatives integral to the housing market recovery.

While this is a list of principal staff, we didnt want to exclude some important voices at HUD, including William Apgar, the former Federal Housing Administration commissioner who is now Secretary Donovan’s senior adviser for mortgage finance; Barbara Sard, HUD’s senior adviser for rental assistance, who was previously the Center on Budget and Policy Priorities’ director of housing policy; and Shelley Poticha, the senior adviser for sustainable housing and communities, who prior to coming to HUD was president and CEO of Reconnecting America.
