MOST SECURITY COMPANIES SEND WHOEVER'S AVAILABLE.
WE SEND WHOEVER'S RIGHT.
Clayton is the region’s premier business address, and it shows. As the St. Louis County seat, Clayton’s Central Business District packs 7 million square feet of office space and 1 million square feet of retail into just two and a half square miles, home to Fortune 500 headquarters, major law firms, and institutions like Washington University’s West Campus and Fontbonne University. That density means constant turnover of employees, students, and visitors, all moving through the same footprint.
Clayton’s residential streets carry their own demands too. Private neighborhoods here hold some of the highest property values in the region, and homeowners expect a level of discretion and consistency that a rotating, anonymous guard rotation simply can’t deliver. GCI builds career-driven security officers who stay on your property, know your tenants, campus, or neighborhood, and take ownership of it like it’s their own.
