I contacted this agency concerning an international, crypto currency fraud scheme. After a good consultation with Kevin, he discussed it with their digital investigations team and decided that I would be better served by an expert in Crypto Currency Fraud and tracking. They spoke with several such colleagues and provided me with solid referrals, domestic and international. An ethical and professional outfit.

I hired INTERPROBE to help locate a lost friend from almost 40 years ago who I met while stationed overseas. I had a common name and approximate age but not much else. They located her in a few days and provided full contact information. They were very fair with me and I highly recommend them.

I am happy to have found this company and I highly recommend them to anyone in need of a really good private investigation service.

Where do I begin. I was referred to Interprobe a few years ago by a good friend. I needed some assistance with a fraudulent trucking deal that span over 4 years in tracking down in 4 states. Interprobe was instrumental in locating 4 individuals, process serving each individual in different states and helping me put together the necessary information for the FBI, US District Attorney and SBA. This information led to a recent 17.5 year conviction. I am very thankful for Interprobe services and the work they performed for me. They were very professional, responsive and fair in pricing for all of the

Aug 26, 2019 Report

When I suspected the very worst was happening, I needed someone in my corner to help me confirm it so that I could make some decisions. Hiring Kevin and his team was the best decision I made. From our very first phone call, Kevin was professional and efficient but compassionate. I was kept abreast of progress in the case and billing was clear. If you need these services, I highly recommend Interprobe.

INTERPROBE was recommended by my attorney. They did a superb job of surveillance work for me. My case was especially difficult because of the preexisting suspicions of the people involved, but this group got it done.
Further, Kevin is the consummate professional and provided me significant support as I traversed this difficult life changing event. Kevin kept me balanced and focused and for that I am forever thankful for his support!
