About Chicago Private Investigators:
A Chicago Private Investigator is a professional trained in the art of investigations and surveillance. In most states, a license is mandatory. Like with an attorney or doctor, Illinois has mandated that certain qualifications, training and experience be required for licensure to protect the public from those who do not have the experience or qualifications to do the job correctly. An Illinois’ private investigator’s training is usually varied and tends to focus on a certain area, again much like a lawyer. Often times that experience comes from law enforcement including the Chicago police department and FBI, military police or research backgrounds. The crux of a Chicago private investigators capability is to take whatever information their client has and to go find whatever information or evidence the client needs to know. The work that a private investigator does is strictly confidential and stays between you and them.

What makes A.S.G. the best choice to be your Chicago private investigator?
Simply put, We Get You Proof, legally, ethically and at competitive prices. While most Chicago private detectives are retired law enforcement people from up north that retire to Chicago and open up a Chicago Detective Agency, working by themselves out of their homes on a part time basis. A.S.G. is the exact opposite. We are Chicago private investigators, working full time in this filed. We are trained, properly equipped and get our clients results. Equally as important, we will not take your case unless we are confident that we are suited to deliver precisely what you requested.
