Pick the wrong investigative firm because you think one size fits all-or because it's in the neighborhood or the price is right-and you could make a huge, costly mistake that's equal to ill-fitting shoes and ignoring customers. Welcome to Investigative Resources of Texas, the hometown team serving the Lone Star State exclusively for over two decades.

It was only after we became a "tried and true" brand that we branched out to other locations because we wanted to be sure we wouldn't compromise on our existing clients by over-extending ourselves.

Few subjects get a conversation pushed into third gear faster than the topic of wire taps. The nation is particularly aware of shenanigans employed by Edward Snowden and the ongoing turmoil resulting from his proclivity to spy and share-first from his desk in Washington D.C. and now from his place in Moscow.
As a role model for the industrialize world, this nation sets a perpetual poor example: in 2012 alone, more than four children died every day as a result of mistreatment. These statistics continue to paint a grim portrait as child abuse reports transect every strata of society: rich and poor, educated versus poorly educated and no religion escapes unscathed when reports of child abuse cases are analyzed by law enforcement authorities attempting to figure out ways to lessen the number of cases brought to their attention.
We Test: When clients suspect computer-related problems, we immediately run a vulnerability assessment to determine penetration damage. Typical of the tests we undertake to increase network uptime are: All WASC, OWASP Top 10, CVE/NVDB/SANS Top 20 vulnerabilities, including data-in-motion leakages, PCI and ISO27001 compliance-friendly reporting, web application VAPT and network vulnerability.
Even if you live in Texas, you may not recall the 2001 Enron scandal - an event considered by many to be the corporate crime of the century. The Houston-based company wound up in bankruptcy, bringing down everyone from highly-placed executives to the Arthur Andersen brand. Shareholders lost fortunes and landmark federal legislation-the Sarbanes-Oxley Act-was passed by Congress to prevent this type of situation from happening again.

Dave is an amazing investigator and person. After several years of searching for a long lost friend of my dad's, I took a chance and sent Dave an email. Just a couple of emails later and he found him! There are no words to express how grateful I am.

My experience with Investigative Resources exceeded all of my expectations. Mr. Cohen took the time to really assess my needs and the situation at hand to make sure no time would be wasted. He was thorough, quick to respond, and more importantly, he got the job done in a timely fashion and put my issue to rest. If anyone is in need of any investigative work, David Cohen is your man. He is a true expert!

My law office used David Cohen's company, Investigative Resources of Texas located in Dallas, Texas in a high profile workers' compensation case spreading from Texas to Pennsylvania with fabulous and outstanding results. Mr. Cohen and his staff offered devoted and persistent investigative measures that revealed the fraudulent nature of the workers' compensation claim that we were defending. Mr. Cohen and his company are extremely reliable and provide services with specificity and integrity. I highly recommend Mr. Cohen and his company fo rany investigative services. Dale Cable, Esq.

David Cohen was very understanding and helpful when I engaged him for support. His team provided professional feedback which covered my request and were very responsive when I had queries/concerns during the period in which I engaged them. I would recommend Dave and his team for investigative services and would happily use his company again if the requirement arose.

It is with high praise and great pleasure that I endorse Investigative Services / David Cohen. I met David Cohen of Investigative Resources, on a Sunday flight to Dallas/Ft Worth. His personable demeanor helped to initiate a conversation that revealed to me that he was a private investigator. At the urging of my friend, I related to David the story of my estranged nephew that I had not seen in more than 30 years and had no luck finding him.

I had pretty much given up. Speaking with David reignited my desire to search for him again. As expected, David offered his services. What was unexpected was what followed. David asked me several routine questions about my relative that I was unfortunately unable to answer with any degree of certainty. For example I did not know my nephew's full birthdate, just the approximate month and year.

I knew his mother's name, but not her birthdate or any previous addresses. I knew the names of two of his siblings, but nothing more. Within two days, David contacted me with positive phone number and address matches for both my nephew and his mother. I was completely blown away by the speed with which he supplied this information given the amount of information I provided him.

With only a partial birthdate and a few related names, David sent me on my way with more than enough to further the search. It then became my responsibility to use the information I was provided to continue the search. Despite several of the phone numbers being disconnected (as expected), I still have sufficient information to continue the search and sustain my hope of reconnecting with my nephew soon.

To say that I appreciate him would be an understatement. He is a compassionate individual with a heart of gold. He proved himself to be quite resourceful and a man of his word. He has provided me a renewed confidence that I can finally provide closure to a situation that has loomed for more than three decades. It's for these reasons that I highly recommend his services.

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.

Dave Cohen provides great service. I've used him more than once and would definitely recommend him to anyone looking for a good P.I. He has a lot of experience, his pricing is fair and reasonable, and he's very responsive and provides quick service.

Dave did a fantastic job on a very difficult assignment. My son-in-law deliberately took himself off the grid to avoid being served with divorce papers and having to pay child support. With minimal information Dave found him in only a couple of days and served the papers. He kept us informed throughout and we could not have been more pleased with his quick and professional response.

Wow! I cannot begin to say how happy I am with the results of David at Investigative Resources of Texas. He was able to not only talk with me about my situation, but handled everything in a very professional and timing manner. He always kept me informed how his status and showed how he is second to none in the business. If I am ever in need to services, he is the first and only call I will make.

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.
