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 very pleased with the quick and professional handling of my case. I was in a difficult situation developing over the weekend that needed fast attention and being overseas made it especially concerning that I would not only find a competent agency but a trustworthy one as well. I am happy to have found this company and I highly recommend them to anyone in need of a really good private investigation service.

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.
