"Mark Carlson is more than just an investigator, he is an addition to your legal team.  He is responsive, complete in his work, and communicates well with both attorneys and their clients.  Mark has helped my law firm achieve great results."
- Jesse Weins, Attorney


"I have used Mark Carlson as an investigator on a number of serious and important criminal cases.  His diligence, intelligence and persistence has been invaluable in helping me in my criminal defense practice.  What makes him unique is he gives me his insight into my cases and helps me formulate defenses for my clients, often times making me aware of things I did not even think of when working my cases.  In short, he is someone who I would and do trust with investigating my cases.” - Marc Milavitz, The Alternative Law Office of Marc Milavitz


“I have used Mark Carlson as an investigator for over a decade now.  I cannot recall a time when I was disappointed with his work product or the timeliness of the work.  When you give Mark a task he gets it done and done ahead of schedule.   Mark’s prior experience as a police officer has proven invaluable on many cases over the years.  Having the ability to know what the investigators should have done and knowing what they didn’t do has resulted in great outcomes for our clients.  I highly recommend Mark Carlson if you need a private investigator.  He will find the answers you need in your investigation.” - Scott Reisch, The Reisch Law Firm, LLC


“As a former member of law enforcement, Mark instinctively sees the prosecutor's strengths and weaknesses in every criminal case.  This experience has been invaluable to my clients.  Mark knows exactly what needs to be done to deconstruct the case to build a winning defense.  Mark has conducted countless interviews on my behalf.  He always knows exactly how to phrase his questions to ensure that I obtain the winning information to allow me to attack the specific elements of the crime in a trial.  Witness interviews, social media monitoring and obtaining the surveillance video that law enforcement neglected to find are just some of the ways Mark has obtained dismissals in my cases.  Technology has changed the way criminal cases are now prosecuted and defended.  Mark’s social media monitoring has single-handily won a life-sentence trial by obtaining a tweet that was subsequently deleted.  Mark has been an integral member of my office for over a decade.” - M. Colin Bresee, Attorney at Law


"On several occasions, I have enlisted Mark's services for various investigative tasks, such as process service, witness interviews, or criminal background research.  Mark performs his work professionally, timely, and with integrity.  Mark's experience with the Colorado legal system has proven invaluable, as his work has directly led to positive results for my clients.  Mark knows where to look, and what to look for.  I wholeheartedly would recommend utilizing Mark's professional services when the need arises."
- Jonathan Datz of The Datz Law Firm, PC, Broomfield, CO 


"I've known Mark Carlson for several years in his previous career as a police detective. I've worked with him on many cases and can say he is the most thorough, professional, and detailed investigator I've used in my practice."
- Steven Barnes of Fossum, Mastro, Barnes & Stazzone, P.C.


"We have to thank you for doing what seemed to be the impossible. With so little to go on, you found our man on the first try. You were so great at keeping us informed with daily updates. You are a true professional! If anyone should find themselves in a situation like ours, I hope they are lucky enough to have you help them. We can't thank you enough Mark for all you did for us."
- David and Ashley from Indiana


"Thank you again for finding her. I did speak to her today after thirty-two years. I appreciate your efforts and honesty for time spent and accountability."
- R.D. from Colorado


"Mark's prior work as a police officer has proven invaluable in assisting us with our civil litigation clients. He is thorough, detail oriented and does, with integrity, whatever it takes to get the job done."
- Irwin & Boesen, P.C.


"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'."
