In 1971, the firm decided to specialize in the area of historic preservation, and museum planning, and design. As a result, the Historic Preservation Program was created, to focus on the preservation, restoration and reuse of historic buildings. Today, the Program employs over 35 architects, planners, engineers, and preservationists, who deal exclusively with the issues related to the continuous use of historic buildings. The Program's impressive record includes numerous successfully completed projects, several of which have received national recognition.
