Zohran Mamdani has tapped Elle Bisgaard-Church, his long-time adviser, to run his incoming staff and shepherd a controversial public safety plan that would send social workers to many 911 calls in New York City. This hire elevates a close campaign strategist with deep ties to progressive organizing and places her at the center of a proposal that cuts police responses to certain non-violent incidents. The move has big implications for how the city will balance public safety, mental health services, and accountable leadership at City Hall.
Mamdani’s pick is being described inside the campaign as the architect of a sweeping Department of Community Safety plan that shifts many non-life-threatening emergency responses away from uniformed officers. That blueprint aims to station mental health professionals and social workers in places like subway stations and other public spaces, signaling a radical rethink of who answers certain 911 calls. Republicans will see this as a direct challenge to traditional policing and a risky experiment in public safety policy.
Bisgaard-Church comes out of an Ivy-adjacent background, with credentials tied to Swarthmore College and Columbia University, and time spent in nonprofit and public affairs roles. She’s been a quiet, effective operator who preferred organizing and policy work to public attention, which is now changing as she takes a visible leadership role at City Hall. Observers note her influence on messaging and on building the coalition that propelled Mamdani’s rise.
The Department of Community Safety plan, as described by the campaign, would reallocate roughly $1.1 billion to stand up a new civilian response system staffed by mental health professionals and social service teams. When designing the proposal, Bisgaard-Church reportedly consulted mental health experts, officials from other cities, and former NYPD leadership to try to shape operational details. That mix of outside advice matters, but critics worry that replacing trained police officers for complex emergency calls risks slower responses and unclear chains of command.
Her role during the campaign extended beyond policy drafting; she organized regular meetings with the local chapter of a national democratic-socialist organization to fold movement priorities into the campaign platform. Bisgaard-Church helped form internal policy tools for that group and played a part in securing its endorsement, which brought organizing power and volunteers to the campaign. For many voters, the visible collaboration between a mayor-elect’s team and movement organizers raises questions about whom City Hall will ultimately answer to.
On her motivations she has been blunt: “I still feel daily, deeply ashamed to live in a place where we allow people to sleep on concrete at night … and I fundamentally believe it doesn’t have to be that way. It represents (a) political choice,” she said in a prior interview, pointing to movement organizations as the place where she found shared outrage and direction. That sentiment frames the new administration’s priorities around social justice and housing, but it also signals a governing philosophy that treats public policy as a corrective moral project rather than a pragmatic balancing act.
Bisgaard-Church has kept a low public profile, rarely posting on social media and speaking infrequently to the press, yet she was widely credited inside the campaign with managing strategy and shaping the affordability agenda. In her own words, taking on the campaign role was “the honor of a lifetime,” and she now positions herself to translate campaign promises into City Hall operations. For residents worried about safety and effective service delivery, hidden hands and back-room coordination are not reassuring.
Republican critics will press for clear metrics, oversight, and pilot programs before redirecting police functions to civilian teams, and they will push for accountability if the city chooses to proceed at scale. The coming weeks should show whether this hire signals careful, evidence-based reform or a wholesale transfer of critical city services to unelected movement partners. How Mamdani’s team implements the Department of Community Safety will be a litmus test for whether this new approach protects New Yorkers or leaves crucial gaps in the city’s emergency response system.
