Welcome to

Now is the time to get to the TRUTH of the Problem.

You're not alone. ASI's team of highly trained private investigators, specializing in Matrimonial Investigations, offer personal coaching and sound advice. When Infidelity happens in a relationship it can be devastating. But don't lose hope, many couples can recover. Recovery can start only if you know the TRUTH and sadly, your spouse is not going to confess to the affair. We will work on getting to the truth together and provide you with the facts in an accurate swift manner.

”Getting answers meant Peace of Mind for me." says Carol, a recent client of ASI. "I am 47 years old. I look good, but my husband made me feel like I was the one who was doing something wrong.”

Carol's story only skims the emotions felt when you suspect someone is cheating on you. People experience denial, hurt, embarrassment, anger, frustration, and depression. Infidelity in a relationship stems from another underlying problem. Whether it be, the couple's first child, money problems, unemployment, role changes, sickness of self or parent; caretaker; taking over the primary role in disrupting the family unit.

You can forgive, but never forget. After ASI does the investigation and discovery of the affair, actions, lies and mistrust come to light and it can ruin the relationship. It will be your decision if you can live with the deceit. Your partner must remain wholehearted to repair the relationship.

You know the situation better than anyone else. You are the one who we strategize with to get the job done. We don't just put an agent out on the case without the proper strategy behind it. We are not a mom & pop agency that only has one man doing all of the work. We don't need to juggle cases. Because we have been in this industry for over 60 years, we have over 600 agents and researchers throughout the United States, Mexico, Canada, Europe and Asia. No island too small, no country too big.
