“I have worked with investigators from Kirby Investigations for over 20 years on a wide variety of cases and am continually impressed with their top notch investigative work. Whatever the assignment is, they complete it thoroughly, on time and within budget. They are excellent communicators, making sure to properly manage expectations and explain results. They have handled undercover work, surveillance, photographic documentation, financial analysis, asset discovery, and courtroom testimony for me and all of their investigators have provided excellent work product and exhibited complete professionalism. I recommend them completely.”
