A familar face on Capitol Square is leaving.

Doug Smith, president of the Virginia Interfaith Center for Public Policy, is leaving to join the staff of the Montpelier Foundation as its director for the Center for the Constitution.

The progressive group lobbies the General Assembly on a variety of issues, such as redistricting and car title loans. It will launch a national search for a replacement to be hired before January’s legislative session.

“The next Virginia General Assembly will be making key decisions related to health care, social safety nets, and how to handle Virginia’s job situation,’’ Smith said. “Interfaith Center members are tenacious advocates for the poor, and I know they will continue to support those on the economic margins.”

Smith is succeeded by interim CEO, Charles Swadley, a former chairman of the Virginia Interfaith Center Board.
