 A device in the physical Office of the Chief Usher reports the location of each member of the first family at all times, so that the chief usher and office staff can stay aware of when the president or family members will be arriving at the White House or what they are doing within the executive mansion.The White House Calligraphy Office—which provides hand-drawn menus, notes, invitations, cards, and similar items—is part of the chief usher's office.However, the Calligraphy Office works most closely not with others in the chief usher's office but with the Office of the Social Secretary (which oversees all entertaining sponsored by the first family).
