Frank Stampf, executive director of the nonprofit Partners In Housing since 2007, is retiring Dec. 31, he announced Tuesday. He’ll be replaced by Mary Stegner, Partners In Housing’s finance officer.

Stampf, who served in the Air Force for 23 years and then worked in defense contracting, started with Partners in Housing in 2000 as a part-time volunteer coordinator. He became director of operations in 2002, and was named executive director in 2007.

Partners in Housing helps homeless families and some homeless single adults with housing for up to two years, and provides support services to help them become self-sufficient.

Stegner worked concurrently as financial manager of Partners in Housing and Catholic Charities before going to PIH full time.
