Brian Mosteller

Mosteller was born in Akron, Ohio, and graduated from Revere High School.[1] He attended DePaul University in Chicago, Illinois, and the Ohio State University in Columbus, Ohio, where he graduated summa cum laude with a degree in international business.[2] He joined the Clinton administration in 1998. There, he traveled consistently for two and a half years advancing President Clinton and then-First Lady Hillary Clinton around the world and domestically.[3] In 2001, he was part of preparations for the 2002 Winter Olympics in Salt Lake City, organizing the bobsled, luge and ski jumping competitions in Park City. His Olympic experiences continued as Operations and Logistics Manager for a private entity at the 2004 Summer Olympics and 2006 Winter Olympics.[4]

Residing in Chicago, Mosteller assisted with the Obama presidential campaign at its inception in February 2007.[5] Working in Iowa, New Hampshire, and other pivotal states, he developed many of the policies and procedures used by the teams organizing the candidate's travels and events.[6] He was involved in the on-site organization of the 2008 primary debates and executed the senator's role at the Democratic National Convention in Denver. Following Obama's election, Mosteller moved to Washington, D.C. and started in the Oval Office hours after the inaugural.[7] Mosteller was one of the longest serving staff members in the administration.[8][9] Anonymous colleagues noted that "if you [want a meeting] at two in the morning, you go through him." [10] In a 2017 interview, Obama said of Mosteller, "He’s a tireless manager and leader with a knack for sweating the small stuff."[11] In West Winging It, a memoir published in 2018, the author references him as "responsible for maintaining dignity throughout the West Wing."[12]

Mosteller is openly gay.[13][14] On August 1, 2016, at his official residence, Vice President Joe Biden officiated at the wedding of Mosteller and Joe Mahshie,[15] a member of First Lady Michelle Obama's White House staff.[16][17]

As of early 2021, Mosteller was the Managing Director of a private family office in Palo Alto, CA.[18]
