With unparalleled professionalism, discretion, and confidentiality, Quest provides its services to multinational corporations, law firms, financial institutions, labor unions, government agencies, educational institutions and regional school districts, and private clients.

One of the most unique and integral aspects of Quest is that its team of expert consultants is comprised almost entirely of former FBI Agents, each with more than 20 years experience in federal law enforcement. Each former agent serves in a consulting area of investigative expertise, creating in Quest, one of the most comprehensive offerings of forensic consulting and business intelligence services in the world.

Other specialists perform additional consulting, technical, and research services in support of Quest's team of experts. Further, Quest's expert consultants network with select former law enforcement officers and intelligence service agents around the world. These highly experienced, multitalented specialists combine their intimate local knowledge and high-level contacts with expertise in specific investigative and intelligence areas.

Quest's consultants have appeared as expert witnesses in federal courts more than a thousand times combined. They also appear regularly on television and radio, and in print, as experts on terrorism, profiling, kidnapping, extortion, organized crime, murder, theft, and espionage.

Founded in 1996, Quest was formed by four former special agents for the FBI to meet the growing demand for corporate security consulting, investigations, information security and computer forensics, and business continuity. A global consulting firm headquartered in the Chicago area, Quest has associate offices located nationally and throughout the world. Quest's comprehensive services are a combination of experience and knowledge brought to the firm by its team of expert consulting investigators.
