About Us

Advanced Surveillance Group is one of Chicago’s premier private detective agencies. Founded in 1999, the agency has established a reputation for investigative excellence in surveillance, information gathering, computer forensic investigations and background investigations.

Our clients range from private individuals in Chicago who may need help on one specific occasion to large Chicago law firms, corporations and national insurance companies.

The Chicago private investigators we work with are experts in their respective fields which include:

  • Computer Forensic Investigations
  • Surveillance
  • Alimony, Cohabitation and Support Investigations
  • Background Checks and Pre-Employment Screening
  • Security and Threat Assessment
  • Interviewing and Statement Taking
  • Locating Witnesses and Parties to Litigation
  • Due Diligence Investigations
  • Asset Searches

We feel that the most important element of our ability to succeed for our clients is our focus on getting you the results that matter to you. Your case is unique, your concerns are real and we treat those concerns as if they are our own. We know that many within our profession are more inclined to provide cookie cutter investigations that are easy to produce, but fail to truly help their clients. We strive to truly deliver the type of evidence and information will truly be of benefit to you.

Finally, we do not conduct investigations of politicians or locate lost loves. We also will not engage in any illegal or unethical techniques as part of any investigation.
