Alexa Herzog

Criminal Justice Manager

Alexa identifies and manages philanthropic opportunities for the Criminal Justice team, focusing primarily on community supervision. Before joining Arnold Ventures, she served as a program manager at the New York City Mayor’s Office of Criminal Justice. In that role, Alexa managed a number of New York City’s efforts to safely reduce the pretrial detention population, including the nationally recognized Supervised Release program, and alternative to detention programs for adolescents. In addition, Alexa supported city implementation of state legislation, including Raise The Age, which raised the age of criminal responsibility from 16 to 18, and the 2020 implementation of the sweeping justice reforms that included overhauling New York’s discovery and bail practices.

Previously, Alexa worked as a senior program associate for the New York City Board of Correction on Rikers Island, the agency charged with regulating and providing oversight for the City’s jails. She also supported the Board’s sexual safety rulemaking process informed by the Prison Rape Elimination Act, and led the Board’s monitoring of Department of Correction compliance with standards limiting the use of punitive segregation. Alexa holds a bachelor’s degree in Social Policy and International Studies from Northwestern University, and served as a New York City Urban Fellow at the Board of Correction and a FELPS (Fellowship for Emerging Leaders in Public Service) Fellow at New York University’s Robert F. Wagner Graduate School of Public Service.
