I was very pleased with Kgriff private investigators. I highly recommend Ryan Coleman, he solved a breach at our company that no else we had engaged previously could.

This is the a great company with a kind and caring attitude. I spoke with Kathy several times while looking into hiring a PI company. I went with Kgriff because they really cared about my situation. The job was done in the same day and could not ask for more attentiveness. Anyone needed this type of service would be wise to check out Kgriff Investigations.

BEWARE! Hired Kathy to do a simple surveillance job at the end of August. I was charged over 150.00 an hour and I put down 2000 dollars on a retainer, after 2 weeks, I didn't receive any surveillance photos or anything. Not only are these prices ridiculous, the investigator lied and said they were at the locations but never took pictures? I tried to talk to Kathy about getting some of my money back, she won't even return my calls. Do not use this firm.

Highly recommend Kathy - she reached out immediately and offered assistance and was able to complete what we needed in a quick turnaround time. She went above and beyond and offered more in service than we expected. I would recommend her and would use her again. This was my first time using an investigator or their services and she made it easy and effortless. Thank you!
