About Strategic Investigations and Executive Protection

Licensed Private Detective Agency serving Illinois

Nature of the Work

Private detectives and investigators are truth-seekers. We are brought in when the facts are hidden, the stakes are high, and ordinary means have failed. Our work spans a wide spectrum — from assisting attorneys building a legal case to helping businesses uncover fraud to giving individuals the answers they need to make life-changing decisions.

Surveillance is one of our most powerful tools. Our investigators conduct extended field surveillance from vehicles and carefully selected positions, using professional-grade still cameras, high-definition video equipment, binoculars, and secure mobile communications. We remain in the field as long as the case demands — patient, disciplined, and invisible until the moment the evidence speaks for itself.

We also leverage comprehensive database intelligence to surface information that most people never know how to find: arrest and conviction records, civil judgments, telephone histories, vehicle registrations, property records, and much more. When digital research and field investigation are combined, the results are difficult to dispute and harder to hide from.

Our team brings hands-on expertise to every stage of a case — conducting structured interviews, executing thorough background investigations, and assembling the evidence into clear, detailed, confidential reports. Whether your matter belongs in a courtroom or stays entirely private, our work product is built to the standard your situation demands.

Strategic Investigations and Executive Protection has been helping clients get the answers they need for over 26 years.
