Big Dom, Philadelphia Eagles' Security Chief Domenico "Big Dom" DiSandro serves as the Chief Security Officer, Senior Advisor to the General Manager, and Director of Gameday Coaching Operations for the Philadelphia Eagles. He's been with the team since 1999, evolving from Assistant to the Chief Security Officer into a multifaceted role that keeps the organization running smoothly behind the scenes.

Core Security Responsibilities

Big Dom oversees all security and safety measures for players, coaches, and executives, including at the team's training complex, during travel, and logistics. He educates the team on the NFL's personal conduct policy, helping maintain a clean off-field record—no Eagles draft pick has faced suspension since 2020. Fans and media highlight his intimidating presence on the sideline, often in Eagles gear, Versace glasses, and a headset, acting as a protector during heated moments.

Draft Vetting Expertise

A key "secret weapon," Big Dom vets draft prospects for character issues, credited with the Eagles' success in avoiding problematic players. Howie Roseman and others praise his role in thorough background checks, contributing to the team's strong player acquisitions without drama. This behind-the-scenes work has made Philadelphia one of the NFL's best at sidestepping "character flaw landmines" in the draft.

Gameday and Sideline Role

As Director of Gameday Coaching Operations, he manages operations near head coach Nick Sirianni, a title added after his 2023 ejection for confronting 49ers' Dre Greenlaw over a hit on DeVonta Smith. Nick Sirianni calls him irreplaceable: "Nobody does their job better... I couldn't do my job without Dom." He's handled fan incidents too, like banning a disruptive supporter during a 2025 playoff game against Green Bay.

Fan Icon Status

Big Dom became a Philly legend post-2023 incident , spawning "Big Dom Security Co." t-shirts and deli sandwiches. Recent forum chatter, like on Reddit, debates his headset and unique sideline "bouncer" vibe—no other NFL team mirrors this. In 2026 discussions, fans speculate he's the ultimate "fixer" for anything from security to coaching logistics.
