Dennis Earl Moore Productions (DEMP) of Brooklyn, an entertainment design and film production company, did the preliminary engineering, technical design, and A/V (audio-visual) design for exhibits and theaters at Mount Vernon‘s aforementioned Donald W. Reynolds Museum & Education Center. This includes the “presentation environments” for fourteen History Channel videos.
DEMP worked with two firms based in Massachusetts, the aforementioned Executive Director James C. Rees, and Education Director Ann Phillips Bay. The firms are Boston-based Christopher Chadbourne & Associates Exhibit Design & Museum Planning, and Cambridge-based Museum Design Associates (MDA). 
MDA described its contribution. “As part of this new, $60-million complex, MDA designed and documented all aspects of new gallery and building construction for the Education Center, including complete interior build-out, security, electrical and display-case conditioning systems and gallery finishes for integration by Project Architect GWWO, Inc. MDA also provided all 3-D exhibit design (casework, scenic recreations, artifact mount designs and layouts, models, dioramas, and graphic integration) and supervised the bid process, budget compliance, gallery preparation, exhibit fabrication and installation.”
A local subcontractor, Design & Production of Lorton, Virginia, did the final engineering and installation work. Art Guild, Inc. was the exhibit fabricator.
Available Light was the lighting designer. Working closely with forensic anthropologist Dr. Jeffrey Schwartz, Studio EIS of Brooklyn created forensic sculptures of George Washington that represent him at the ages of nineteen, forty-five, and fifty-seven.
The six-foot-high sculpture of George Washington’s head at the entrance of the Donald W. Reynolds Education Center was conceived by Dennis Earl Moore himself. “At first glance, the head appears to be a convex sculpture,” explained Moore, “but on closer examination it is actually a negative sculpture – concave – in which the eyes and the nose and the face and the head appear to turn and follow you around. Lighting is part of the illusion. It’s an old magic trick. And it plays on the concept of getting inside George Washington’s head.”
DEMP created, produced, and directed the Revolutionary War Theatre and the Legacy Theatre. Moore has a background as an IMAX filmmaker. He produced and directed Flyers and Living Planet for Francis Thompson.
Around their midpoint through the facility, one encounters the 110-seat Revolutionary War Theatre (also known as the Elizabeth & David Bruce Smith Theatre). There, one views a fourteen-minute long video about the Battles of Boston, Trenton, and Yorktown. Moore explains, “In Boston, he became a hero of the people. In Trenton, a general. In Yorktown, he became a commander and diplomat of international stature.”
The last stop is the Legacy Theatre (also known as the Gay Hart Gaines Theatre). It is a 360-degree wraparound cinema with thirteen projectors has a diameter of forty-four feet and can accommodate 110 people. The five-minute video includes General Colin Powell, historian David McCullough, and the Grammy-winning Brooklyn Youth Choir.
