One of the few great p.i. agencies with a immaculate reputation of integrity and a wealth of experience. Donna Snelling is exceptional.

Mar 05, 2016 Report
I enlisted Snelling Private Investigators' services because I was dealing with a very unscrupulous contractor business. There is a long list of other clients that this business ripped off besides me. They gave me all that I needed, including court records, and found the owner who has moved. They are professional, comprehensive and quick with results. I would definitely recommend their services and I would use them again should the need arise. It could have saved us a lot of money had I contacted them first about this business before doing business with them. Always know who you are doing business with!
Jim Landon

Snelling Private Investigators helped us with some private investigation at a crucial time. Among other things, they uncovered relevant background information that had been unknown to us
Tony Corrie
I was put in contact with Snelling Private Investigators for some investigation work I needed doing in the States. I found Donna to be very thorough, fast and above all, accurate in the information provided to me. I would have no hesitation in recommending Donna and her company.
