Account Managers

At the heart of Chicago Five-O’s quality assurance program is a team of dedicated Account Managers who work on a daily basis with client management staff and security directors. Account Managers are involved in all phases of a client’s operation, as appropriate, and report directly to Chicago Five-O’s senior management.

Supervisory Team

The key to a successful security program is consistency and accountability. Both are achieved through quality supervision. Chicago Five-O places a great deal of emphasis on ensuring each client receives consistent quality service by accountable individuals—leading to a successful security program.

Our supervisory team includes roving security managers who provide immediate response to occurrences and provide Chicago Five-O management with information regarding the performance of the security officers assigned to a specific site. Chicago Five-O’s quality assurance program uses incentive and motivational activities to ensure a high level of performance and compliance with company, industry and state standards and requirements.

All Chicago Five-O supervisors meet rigid training standards prior to assignment. In addition to basic security training, they successfully complete supervisory training that pertains to their assigned worksite. Our supervisory personnel also receive management training on topics such as public speaking, developing and writing post instructions and advanced customer service with an emphasis on problem solving.
