As co-owners of Third Chair Investigations LLC, Miles Brissette and Bob Gill take the investigations business very seriously.  They set out in 2016 to build the best private investigations company in North Texas.  In two short years they have built a company that can handle any type of investigation from a simple DWI case to a capital murder case to a complex family or civil case.


Bob developed the expertise to handle private investigations through years of being in the trenches as a criminal trial attorney; from both the prosecution and defense sides of the bar.  He also spent over fourteen years on the felony district court bench.  Having been involved in the trial of hundreds of complex criminal cases, Bob knows what it takes to put together a successful case.


If you are looking for a private investigations company that understands what you need because they have been there themselves, you need look no further than Third Chair Investigations LLC.  Bob will be glad to assist you with your case by employing his full range of legal experience.
