"I strongly endorse Mark Carlson for his superior work as a private investigator. I have utilized Mr. Carlson’s professional services in several very complicated and serious criminal cases in the past. I have always been very pleased with his comprehensive and thorough work on my cases. Few investigators have Mark’s exceptional ability to obtain interviews, formulate the right questions, and then draft timely accurate reports. More than just witness interviews, I have utilized Mark’s significant criminal law experience in formulating, modifying and delivering winning defense theories at trial. Mark has achieved an exceptional reputation within the defense community because of his significant body of defense work. On several occasions, Mark has identified serious issues which were overlooked by prosecutors and detectives that became focal points for jury acquittals. Similarly, Mark has often identified serious problems with defense witnesses that proved critical in defending substantial criminal allegations. There are not many investigators who I recommend that my clients hire to actually sit at defense table during trial, but Mark Carlson is one of them because his input during trial is so frequently valuable. If you are looking for an exceptional defense investigator to assist on your case I suggest you look no farther. Hire Mr. Carlson and you will see why he has earned a reputation among this state’s top defense attorneys as 'the very best'."
