A licensed, insured, and minority-owned firm specializing in small to large-scale event security, staffing, and safety management — built on a foundation of community trust and decades of frontline experience.
Founded in 2015 in Chicago, Greenroom Security Agency (GRS) began securing film and studio lots and green rooms — and has grown into one of the city's most trusted event security providers. Today we serve the City of Chicago, Special Olympics, the Chicago Park District, and dozens of high-profile event producers across Illinois and neighboring states.
GRS operates under the methodologies and standards of ASIS International, NIMS, ICS, and FEMA's Whole Community Approach — delivering measurable safety outcomes while prioritizing guest experience and professional presence at every deployment. The result: a zero-incident record across more than 300 events.
Eugene Posey is an accomplished Security Director and Licensed Private Security Contractor with over 30 years of experience — including 18 years as a Chicago Police Department patrolman. He holds an MPA in Public Safety Administration from Calumet College of St. Joseph.
As Founder and Director of Security for Greenroom, Eugene has led operations across high-attendance festivals, citywide special events, amphitheaters, and hospitality venues where safety, guest experience, and brand protection must operate in lockstep. He commands deployments of up to 100 personnel across multi-day events serving 25,000+ attendees per day — overseeing unified command, staffing logistics, credentialing, ingress and egress strategy, and real-time incident response in continuous coordination with venue leadership, city agencies, fire, and EMS.
Greenroom and its leadership maintain the licenses, certifications, and affiliations that serious event organizers and city agencies require.
From planning to the final encore, Greenroom keeps your event safe. Let's talk.
