Mayor Zohran Mamdani, who was inaugurated on January 1, 2026, has indeed appointed a key figure, Elle Bisgaard-Church, to lead the implementation of his public safety overhaul. Bisgaard-Church, who served as the "chief architect" of Mamdani's campaign platform, was recently named his Chief of Staff (or chief advisor). She is the primary driver behind the creation of the Department of Community Safety (DCS), a new agency designed to shift certain responsibilities away from the NYPD.
