Leah Greenberg and Ezra Levin are the coauthors of the Indivisible Guide and co-Executive Directors of Indivisible, where they lead a national staff in Washington, DC, and across the country supporting the Indivisible movement in advocacy, elections, and grassroots organizing. The two have been listed in the Politico 50 list, GQ&;s 50 Most Powerful People in Trump&;s Washington and Roll Call&;s People to Watch in 2019.

Leah was a human trafficking policy advocate before joining the office of Congressman Tom Perriello on Capitol Hill. Working for a progressive in the red fifth district of Virginia at the rise of the Tea Party, she saw firsthand the power that organized constituent power could have&;and she took notes. After Perriello&;s loss in 2010, she returned to human trafficking policy&;until the 2016 election, when she started writing a quick guide to constituent power with her spouse Ezra.

Before Indivisible, Ezra was a congressional staffer and anti-poverty advocate. He started out working on local homelessness issues, and during the late Bush II and early Obama eras he served as a senior legislative and campaign staffer for Congressman Lloyd Doggett (D-TX). He escaped Capitol Hill and spent a few years as a think tanker and advocate, writing papers on progressive tax policy that Leah begrudgingly edited and trying to get Congress to listen about anti-poverty reforms.
