My company had to use Dave Cohen’s services as part of a state application process. I had spoken to several other investigative firms but none could really provide me what I needed despite clear parameters. When I spoke with Dave, he knew exactly what I needed to have investigated (which was absolutely incredible) and was able to give me a very fair and reasonable price for his services. He always communicated with me as to the status of his progress and answered all my emails within a couple hours if not minutes. Investigative Resources will be my first stop should I need a similar service again. If you’re reading this review and looking for a good PI – call Dave. You won’t regret it.
