Success Stories


I just wanted to send you another huge thank you.  I was able to get ahold of Mr. Dean and reconnect him with my father tonight.  Your kindness means the absolute world to me and my family.  I already left a Google review and told everyone I know on Facebook, I'll hit up Yelp tomorrow.
Thank you,

Well I want to say Dave Cohen and Investigative Resources is the best, most thorough and honest private investigator there is! He is affordable and has a real compassion for his clients. He is extraordinarily talented and just superb at what he does! I couldn't ask for a more professional and competent person than Dave and his company! I wholeheartedly recommend him!

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.

David Cohen is incredible. He is a very compassionate gentleman who does business is a very straight forward way. I would recommend his services to anyone who wants to deal with a legitimate business man who genuinely cares about people. Also, I rarely use yelp and I am writing a review for David because I truly believe he is a gifted and professional businessman.

I have used Investigative Resources of Texas for surveillance on a problem employee and the results were very beneficial. Dave Cohen is a honest and capable investigator. The next time I need a Private Investigator, for any reason, I will call Investigative Resources of Texas.

Dave Cohen is extremely detailed, knowledgeable, and energetic professional. His background checks, that one would use in reviewing candidates for different levels of employment, are very in depth and use all current data...not dated data like many use. When it comes to investigation, Dave's experience will get you all information possible. I am always pleased to refer him and have done so on numerous occasions.

Wanted to let you know that we received confirmation today that the passports for our niece and nephew have been issued in Canada for American citizenship.

This was due in large part to your assistance and ability to get us the information we required on time and in particular with the precision necessary.

We are grateful to you and would highly recommend you to other clients.

5 Stars for Investigative Resources of Texas

My company was involved with a single motor vehicle (a motorcycle) accident in one of our work zones. We were notified by the injured driver’s attorney that we were being sued for a multitude of different issues. The case appeared to be one of those that we had no chance of winning and our insurance company was ready to talk about settlement.

As a last resort we requested a professional investigator to take statements from all parties involved and were fortunate to get David Cohen.

David Cohen exceeded company expectations through his superior efforts. He was able to prove that the driver was negligent in his actions and that my company was not liable for injuries and damages. His efforts resulted in a savings of approximately $80 k!

I highly recommend David Cohen, Investigative Resources of Texas to anyone who has investigative needs.
