Despite the unusual title, the chief usher oversees all activities in the White House residence and works as general manager of the building, handling everything from the large staff of butlers, maids, chefs, florists and electricians to fiscal, administrative and personal duties.
The chief usher also works closely with the first family, including providing guidance on the furnishings, art and decor.
Reid, who previously worked for the Ritz-Carlton hotel group, joined the White House in 2011 under President Barack Obama.
She replaced the first African American chief usher, Adm. Stephen W. Rochon, when he left to take a job at the Department of Homeland Security.
Douglas Brinkley, a presidential historian and professor of history at Rice University, said that it is highly unusual for an administration to fire its chief usher, especially without providing any explanation. "If there is a very compelling reason for the dismissal, the White House needs to tell the public" he said. "Otherwise it comes off as cruel."
White House officials provided no further explanation for Reid's abrupt dismissal.
Sudden dismissals from the White House's permanent staff are rare. The last one that people interviewed for this story recall was in 1993, when the Clintons fired an assistant usher who had a friendly phone conversation with Barbara Bush that was thought to be inappropriate.
"Knowing Angella, I doubt seriously that she would have done something herself to cause this," said Stephen Rochon, Reid's predecessor. "She worked for years in top management in hotels. She knows about hospitality. She is definitely professional but you're not going to please everybody."
Reid was said to be close to the Obamas, who hired her for the job, but three people with knowledge of the situation said there were tensions with the household staff she managed.
"For the staff, she was a little tough on them because they could be free-wheeling," said a former White House official, who is frequently in touch with the residence staff and requested anonymity to describe the personnel situation.
Anita McBride, who served as chief of staff to Laura Bush, spoke highly of Reid but said her background in the hospitality sector may have left her less prepared for the transition between administrations than other White House residence staff members, who had served both Democrats and Republicans in course of their careers.
"These are the people that have the most intimate details and knowledge of how you live your life," McBride said of the relationship between the household staff and the first family. "You just come on board and you have to click, in the past it would not have occurred to [a first family] to make a change at the top like that. . . . There was more of an expectation that there are certain things that come with the White House."
