O'Malley Dillon served as White House deputy chief of staff for the first three years of Biden's presidency, after managing his 2020 presidential campaign.

## Early life and education

O'Malley Dillon's great-grandparents were Irish Catholic immigrants from Gorumna Island, County Galway. Born in the Jamaica Plain neighborhood of Boston, she has three siblings. Her parents are Kevin O'Malley, a school administrator, and Kathleen O'Malley. When she was a child the family relocated from Jamaica Plain to Franklin, Massachusetts, to be closer to her father's job.
O'Malley Dillon graduated from Franklin High School in Franklin, Massachusetts. In 1998, she graduated with a bachelor's degree from Tufts University, where she majored in political science and captained the softball team. O'Malley Dillon decided she wanted to work in politics while on a family vacation to Washington, D.C.

## Career

O'Malley Dillon's first role in politics was answering phones for Massachusetts attorney general Scott Harshbarger. She joined Al Gore's 2000 presidential campaign as a field organizer in 1999 and rose to become a regional field director by the end of the campaign. She worked as a field director for the U.S. Senate campaigns of Tim Johnson and Mary Landrieu. In 2003, she worked as Iowa field director for John Edwards's 2004 presidential campaign, and, after Edwards left the race, became deputy campaign manager for Senator Tom Daschle's reelection campaign.
In 2007, O'Malley Dillon again went to work for John Edwards on his 2008 presidential campaign as his Iowa state director and later deputy campaign manager. After Edwards was again eliminated, she joined Barack Obama's presidential campaign for the general election as battleground states director. After Obama's election, she worked on the presidential transition as associate director of personnel, and then was hired as the executive director of the Democratic National Committee under Tim Kaine.
In 2011, O'Malley Dillon joined Obama's 2012 reelection campaign as deputy campaign manager, contributing to Project Narwhal. After Obama's reelection, she co-founded the political consulting firm Precision Strategies with fellow Obama campaign alumni Stephanie Cutter and Teddy Goff. She led Precision's consulting effort for the Liberal Party of Canada in the 2015 Canadian federal election.
After the 2016 United States presidential election, O'Malley Dillon chaired the Democratic National Committee's Unity Reform Commission. In 2019, she was involved in an effort by Democratic Party data and political personnel to create a data exchange to allow for greater information sharing between Democratic campaigns and allies, a project that party leaders see as crucial for catching up with the Republican data program. Later in 2019, she was hired as manager of Beto O'Rourke's 2020 presidential campaign.
Through Precision, O'Malley Dillon also advised Gates Ventures, a venture capital firm founded by Bill Gates; the Chan Zuckerberg Initiative, founded by Mark Zuckerberg and his wife, Priscilla Chan; General Electric; and Lyft; her deferred compensation and severance from Precision was at least $420,000.
In April 2020, O'Malley Dillon was announced as the new manager for Biden's 2020 presidential campaign. She succeeded Greg Schultz and Anita Dunn, who had shared campaign management duties for the previous month and remained with the campaign as senior advisors. O'Malley Dillon was the first person to serve as Biden's campaign manager who was not related to him. Biden's sister, Valerie Biden Owens, had served as Biden's campaign manager for all his previous campaigns, but only served in a senior advisory role in his 2020 presidential campaign. On November 16, 2020, it was announced that O'Malley Dillon would assume the role of White House deputy chief of staff in the administration.
In January 2024, it was reported that O'Malley Dillon planned to leave the White House to become Biden's 2024 reelection campaign chair.
On July 1, 2024, in response to worries about Biden's performance in his June 27 presidential debate with Donald Trump, O'Malley Dillon told members of the Biden campaign's National Finance Committee that he was "probably in better health than most of us".
On July 22, 2024, the day after Biden announced that he was ending his 2024 presidential run, Vice President Kamala Harris announced to campaign staff that O'Malley Dillon would manage her campaign for president. O'Malley Dillon oversaw campaign finances and played a key role in most major decisions, with the campaign spending around $1.5 billion over 15 weeks. Harris lost the general election to Trump.
