Emery began his career at the White House as a computer specialist after answering a job advertisement in The Washington Post. Soon, White House Chief Usher Gary J. Walters hired him to replace the retiring Nelson Pierce as an assistant White House chief usher. Emery served as an usher in the Reagan Administration beginning in January 1986. In this capacity, he worked in a four-person office to oversee the White House estate, including managing the 89 residence staff. In addition, part of Emery's job was to carry out White House functions such as receptions, dinners, and conferences. In so doing, Emery worked in tandem with the First Family, the White House staff, the chief usher, the press office, the Secret Service, and military leaders. Emery gave personal tours of the White House to private guests including some notable figures such as: Barbra Streisand, Dana Carvey, Ted Williams, Joe DiMaggio, Julia Roberts, Tom Hanks, Julie Andrews, Johnny Carson, and Melanie Griffith.
Bill Clinton years and firing
On March 3, 1994, Emery's unusually abrupt firing was the subject of nationwide news when Hillary Clinton dismissed him for communicating with former first ladyBarbara Bush. Despite passing several FBI investigations and background checks, Emery was fired by Hillary Clinton for "an incredible lack of discretion" after communicating twice with the former first lady. He was the first-ever White House usher to be fired. A White House usher does not typically change with administrations. White House Chief Usher Gary J. Walters, was not permitted by the White House to testify before a Congressional subcommittee on Emery's dismissal. This led to some suspicions on Capitol Hill that the White House was attempting to avoid scrutiny about the firing.
Post-White House years
Council Administrator
After his dismissal from the White House, Emery worked for eleven months as a computer consultant. In March 1995, he was appointed council administrator of Howard County, replacing former University System of Maryland assistant vice-chancellor Dr. Sheila Tolliver. As the council administrator, he oversaw a staff of 25 people with an operating budget of about $1 million. Views on his tenure are split along party lines. He has earned the praise of Republican Council Chairman Charles C. Feaga and Allan H. Kittleman. In June 1996, Emery publicly clashed with Democratic Councilman C. Vernon Gray over his misuse of county funds and resources to aid in his campaign for a position with the National Association of Counties. Weeks later, Gray wrongfully accused Emery of leaking NAOC campaign letters to The Baltimore Sun. Emery was vindicated by the Howard County Police Department; Gray subsequently found his letters in a different file in his office. Effective December 4, 1998, Emery resigned when Democrats regained the majority on the Howard County Council.
After his time as a council administrator, Emery returned to the federal government as a supervisory information technology specialist at the Architect of the Capitol where he later served as the director of information resources management. Emery was promoted to chief enterprise architect of the AOC beginning in 2007. In this capacity, he oversaw the enterprise and technology management of the U.S. Capitol, Senate, the House of Representatives, the Library of Congress, and the Supreme Court. He contributed, along with other information enterprise professionals from the federal government, private sector, and academia, to the publication of The Integrated Enterprise Life Cycle: Enterprise Architecture, Investment Management, and System Development. With colleagues at the AOC and the National Science Foundation, Emery also published a paper for the 40th Hawaii International Conference on System Sciences. In 2009, he became the chief information officer of the AOC. In 2010, Emery served as the director of portfolio governance in the Office of the Chief CIO for the U.S. Department of Homeland Security. Two years later, in December 2012, he became the first chief information officer of the United States Department of Justice National Security Division. There he served on the DOJ CIO Council to help develop the strategic plan for the Department's information and technology goals for fiscal years 2015–2018. Emery currently serves as the chief enterprise architect for the U.S. Securities and Exchange Commission.
