Here is a Profile of Darienne M. Page ROTUS (Receptionist of the United States) from the New York Times
Ms. Page presides over the beehive of activity that is the West Wing lobby of the White House. At 27, she is among the hundreds of young aides who help the new administration tick. But her vantage point offers a considerably closer view of this presidency than most of them.
She is on hand to greet nearly every official visitor who has an appointment with the president or his top advisers. She oversees the front of the house at 1600 Pennsylvania Avenue, serving coffee to former Prime Minister Tony Blair of Britain, making small talk with a delegation from Kazakhstan and trying to chew a mouthful of almonds quickly before saying hello to Tiger Woods as he stands at her desk.
This is her first White House job, but Mr. Obama is the second president she has served. The first was George W. Bush, her commander in chief when she was an Army sergeant stationed in Iraq.
Ms. Page joined the military after finishing high school in Maryland, following a long line of others in her family. She worked as a paralegal in Baghdad, taking depositions in the Abu Ghraib prison. She still wears a metal bracelet on her right wrist inscribed with the name of Sgt. Maj. Cornell W. Gilmore, her commander, who was killed when enemy fire struck his helicopter in late 2003.
