Located in Maryland just outside Washington , DC,  Georgetown Prep School grew out of Georgetown University in the late 19th Century in response to a need to separate secondary and collegiate students at the main campus.

The Georgetown Preparatory School initiated a new master plan in 1990 in response to a Long Range Planning Study which envisioned adding a new Performing Arts Building, a new Field House and classrooms to their Georgian Revival campus of 90 acres in Rockville, Maryland.  As part of the master plan, a thorough site, traffic and programming study was undertaken to identify opportunities and constraints on the campus and provide a basis for future growth into the 21st Century.  The resulting master plan not only documented all the various buildings on campus and addressed zoning issues related to new entrances, it also provided the school with a plan to build the new Haas Humanities Building and  Theater complex which completed and complimented the original 1915 master plan of a central Georgian quadrangle.  This complex was completed in 1995 and contains new classrooms, music faculty offices, board room, art department and a 400 seat theater/auditorium.
