Retirement of a Respected NYPD ESU Sergeant Marks Over Two Decades of Service

A distinguished instructor and leader within the NYPD’s Emergency Service Unit (ESU) recently concluded an over 20-year career with a heartfelt farewell ceremony. The event drew numerous colleagues and officers who honored his contributions to the department.

The farewell walk took place at Floyd Bennett Field in Brooklyn, a historic training site where many current ESU officers received their foundational skills. Sergeant John Flynn, a beloved figure in the unit, received recognition for his dedication and numerous leadership roles, including leading 11 ESU training courses.

Flynn was celebrated for his involvement in high-stakes rescues and critical incidents. One memorable rescue involved a rattlesnake bite on Bear Mountain, where he assembled a team, assisted in stabilizing the victim, and coordinated her rescue via helicopter—all while ensuring she received vital antivenom treatment to save her life. Flynn expressed pride in safeguarding a fellow New Yorker, emphasizing the thrill and impact of his work.

Throughout his career, Flynn responded to a diverse array of emergencies, from rescue missions to tactical operations. He credited his team and fellow officers for the city’s safety, highlighting the heavy responsibility they carry each day. “It’s a tremendous obligation,” he said, “but absolutely worth it.”
