In February 2026, during her first week as New York City’s Emergency Management (NYCEM) Commissioner, Christina Farrell (ELP2101) walked into a historic blizzard.
Just days into the role, a winter storm (dubbed Winter Storm Fern) rapidly intensified, shutting down parts of the city and forcing decisions which hadn’t been made in years: a travel ban, a state of emergency, and a citywide wireless emergency alert.
Within 48 hours, Farrell was coordinating the response to one of the largest blizzards New York City had seen in nearly a decade, all the while settling into the commissioner’s chair. The storm dumped roughly two feet of snow, which was the city’s heaviest in 10 years, with temperatures below those recorded in parts of Antarctica. For weeks, the city contended not only with recovery, but with heightened risk to unsheltered New Yorkers, which would include multiple fatalities.
“The city has to keep running,” Farrell said. Her agency, NYCEM, is a relatively small agency by city standards, but responsible for coordinating some of the largest, most complex operations in the country.
Increasingly, many of the people at the NYCEM share something in common: an education at the Center for Homeland Defense and Security (CHDS).
Across NYCEM, CHDS alumni are shaping how the agency thinks and operates. What began as individual professional development became an informal, powerful pipeline for leadership, collaboration, and succession planning in one of the most demanding emergency management environments in the world.
For Farrell, the value of CHDS was clear long before she attended the Executive Leaders Program.
“I had been aware of the program for years because so many of my colleagues went through it,” she said. “They came back talking about collaboration at the federal, state, local levels, and with the private sector. That’s what emergency management is.”
She joined CHDS in 2021, seeking a challenge beyond daily operations. She looked for an opportunity to think differently about leadership, risk, and governance.
“It was really fantastic,” she said. “The professors, the material, but also the people. You had very different viewpoints and could sit down and have real conversations.”

Those conversations extended well beyond the classroom.
“You’d have spirited disagreements during the day, and then keep talking at night,” Farrell said. “That kind of environment is missing in a lot of places.”
After completing the ELP at CHDS, Farrell’s career spanned a period of escalating risk for NYC marked by extreme weather, increasingly dense event schedules, and emergencies which lasted from days to months. The most profound event happened between 2022–2023, when the arrival of thousands asylum seekers required the city to rapidly design and operate a humanitarian shelter system, all while continuing to manage its everyday emergency responsibilities.
“We ended up setting up about 17 shelters for roughly 6,000 people,” Farrell said. “That’s something we had never done before outside of hurricanes.”
These experiences have shaped how NYCEM now develops its leadership. Today, NYCEM has at least 10 CHDS alumni on staff, with additional employees participating in the Master’s, Emergence, and Executive Leaders programs.
“It’s definitely the gold standard,” Farrell said of CHDS programs. “All the executives here want to do it.”
One of the clearest examples is Ira Tannenbaum (ELP1402), a longtime NYCEM leader and 2015 ELP graduate, who now serves as an Assistant Commissioner, overseeing external affairs and strategic partnerships.
By the time he attended CHDS, Tannenbaum had already spent years building connections between NYCEM and the private sector. He said the program enhanced his understanding of how networks function. One of the key takeaways from the CHDS classroom was how people collaborate under pressure.
“A lot of the discussions were about terrorism,” he said. “But really, what stuck with me was human behavior: how people form networks, how they communicate, how they work across differences.”
Those insights now shape his daily work. His portfolio has expanded significantly since CHDS, moving beyond private‑sector outreach to encompass regional, intergovernmental, and cross‑sector coordination.
“Collaboration isn’t optional anymore,” he said. “It’s how you solve complex problems.”
That perspective echoes across the agency. Ryan Dwyer (MA2303/2304) is an NYPD sergeant who transitioned into a planning role at NYCEM. He credited CHDS with reshaping his career trajectory. Before joining NYCEM, Dwyer’s work was tactical security, where he was assigned to City Hall protection and major events.
For Dwyer, the CHDS’s Master’s Program reframed emergency management as a strategic discipline focused on anticipation, rather than moment‑to‑moment response. Midway through the program, Dwyer moved into a citywide planning and coordination role at NYCEM, which expanded both his scope and influence.
“I started the program working security at City Hall. Now I’m involved in planning at a level I didn’t think I’d get to,” he said, adding that the multidisciplinary aspect of CHDS was integral to him professionally. “I was exposed to practitioners from across the country. You realize there are different ways to do things, especially when people don’t have the same resources.”
“A lot of the discussions were about terrorism. But really, what stuck with me was human behavior: how people form networks, how they communicate, how they work across differences.”

That broader perspective is essential to the safety of New York City, as NYCEM is currently preparing for one of the most complex operational periods in its history. In Summer 2026, NYC plans to manage multiple, overlapping events which will strain every element of the emergency management system: transportation, public safety, health, communications, logistics, and regional coordination.
“When everything is happening at once, you don’t get the luxury of focusing on a single event,” Farrell said. “You’re managing the city as a system, all under pressure, at the same time. The work is making sure those systems don’t just respond, but hold together.”
The first major event the NYCEM will support is the FIFA World Cup, which is being hosted five miles away from NYC at the MetLife Stadium in East Rutherford, NJ. Farrell and her team are preparing to handle the secondary effects which inevitably spill into the five boroughs after major sporting events, including fan zones, mass transit surges, spontaneous celebrations, high‑profile visitors, and heightened security postures.
The MetLife Stadium will host eight FIFA matches, including the Final on July 19, 2026. Dwyer explained that the city will continue to execute its regular summer calendar of large‑scale events, including Pride Week, the Puerto Rican Day Parade, outdoor concerts, street festivals, and professional sporting events. Many of these events occur on the same weekends, even within blocks of each other, which can shrink planning timelines and stretch operational capacity.
“From the outside, events look separate. On our end, they stack,” Dwyer said. “You’re planning Pride, a parade, and a major international event at the same time, often in the same geography. That’s where coordination becomes the operation.”
This summer, New York City will also play a central role in the United States Semiquincentennial, including a specialized Navy/ Coast Guard Fleet Week, and an International Naval and Aerial Review which will bring ships, aircraft, international partners, and global attention to New York Harbor.
“It’s going to be a Fourth of July like nothing ever before,” Dwyer said.
Preparing for that convergence requires more than incident command structures or event‑specific playbooks. It requires leaders who already understand how to operate across agencies, jurisdictions, and sectors, because they’ve been doing it together for years.
Inside the NYCEM, the network effect is visible. Participation in CHDS has become both a professional aspiration and an institutional norm. Over time, that dynamic has created a self-sustaining pipeline.
For Farrell, that conduit is essential for the future of the agency. Hazards are evolving. Events are getting larger. Local agencies are becoming more self-reliant.
“What we’re planning for now isn’t just this summer, it’s the next era of events in New York City,” Farrell said. “The scale is bigger, the timelines are tighter, and the expectations are global. That means our preparation has to be smarter, not just larger.”
From the blizzard that marked Farrell’s first week as commissioner to an upcoming summer stacked with numerous major events, the NYCEM knows that readiness doesn’t happen all at once. It is built over time, through shared experience and a common approach to problem‑solving. And those lessons were learned in a CHDS classroom.
“CHDS reinforces the way we want this agency to think: strategically, collaboratively, and ahead of the curve,” Farrell said. “That’s how we prepare for what comes next.”
