With headquarters in St. Louis, Missouri, Whelan Security is a privately-held, family-owned company providing contract security services across many diverse industries and vertical markets including corporate headquarters, commercial real estate properties, financial institutions, educational campuses, manufacturing & industrial facilities, retail shopping centers, residential communities, and sensitive government facilities throughout much of the United States.
In addition to traditional security service, the company also offers uniformed security and staffing services to major events (including collegiate and professional sports venues, convention centers, and political conferences) and provides emergency response services to natural disasters, labor disputes (including strikes and work stoppages), plant shutdowns, and industrial accidents.
Founded in 1949, Whelan has enjoyed a rich heritage of service excellence rivaled by few in the contract security industry. While other security companies have merged, consolidated, downsized, or sold, Whelan is still owned by the same family and driven by the same principles of integrity and conservative business ethics that it was founded upon more than six decades ago. Driven by an employee-centric culture and a performance based business model, the company has grown to become one of the largest security companies in the United States.
