I started this investigation on a fixed budget and toward the end of it I could not afford to spend any more money. After speaking with the investigator joe he told me that he would finish it with out any further cost to me. Anyway the investigation got me all the information I wanted. Thanks joe

Though we are across the country from Chart House, we experienced quick response to our initial inquiry. This response was professional, comprehensive, and thoughtful. Further communications built on this initially good impression. Adam is an impressive investigator, from his initial response to his detailed, timely responses. Thank you Adam!!! Dennis I

Mr. Paul Graf assisted us with a multi-state investigation commencing 2012. He was highly professional, on time and detailed in his work. Our case was complex and required an in-depth understanding of Federal as well as various States' respective criminal, cyberbullying and anti-trafficking laws. He exhibited patience during the entire process. We were so pleased with his work that we asked him to do a second report for us. I highly recommend Mr. Graf for work from a domestic (or overseas) background check to a more in-depth and complex analysis and investigation.

Ken is a phenomenal private investigator. He got video proof that my husband was cheating on me. He also ran a background check on the mistress that revealed a history of drug problems with court intervention. This information was helpful to secure full custody of my children. He was very professional and understanding with my sensitive situation.

I was really upset over an issue which had happened the morning I spoke to Glen. He talked me off the ledge, so to speak. I think we spoke for about 2 hrs. I found him understanding, kind and a great listener!
