Zachary Iscol, Commissioner

Commissioner Zach Iscol

A crisis tested leader, Zachary Iscol has led in settings ranging from combat operations in Iraq to the frontlines of COVID-19 pandemic and Hurricane Sandy here in New York. His experience includes building a pioneering nonprofit mental healthcare provider, leading one of the premiere military journalism outlets, and serving as a strong advocate for immigrants and underserved communities. Two of his former commanding officers cited him as the officer they would personally select to lead their sons into combat.

As a Marine, he served two tours in Iraq and on other assignments throughout Africa and the Middle East. During his second tour of duty, he led a combined unit of US Marines and Iraq soldiers in some of the heaviest fighting of the Iraq War during the Second Battle of Fallujah, where he was awarded a Bronze Star for valor. He later helped build many of the components of the Marine Corps' first special operations command and deployed on one of the first MARSOC teams to deploy overseas.

Over the past decade, Iscol has built and led businesses and a nonprofit mental healthcare provider, the Headstrong Project. The Headstrong Project now cares for over 1,000 veterans a week in 30+ cities and counting to provide world-class, cost, and bureaucracy free mental healthcare veterans and service members need to recover from hidden wounds and get back to the best versions of themselves.

At the height of the COVID-19 pandemic in New York City, Iscol led over 40 federal, state, and city agencies as the deputy director of Joint New York Medical Station, one of the largest and only successful COVID field hospitals in the country.

A 2001 graduate of Cornell University, he was the youngest recipient of Phillips Exeter Academy's John Phillips Award, a member of the 2013 Team USA for USA Triathlon, and a grand marshal of the 2019 New York City Veterans Day Parade. In 2007, while still on active duty, he testified before the United States Senate about the need to protect Iraqi refugees, especially translators and others who put their lives in danger to help US forces.
