“I highly recommend RCM Investigation. They are extremely professional and are the most complete team of investigators with whom I have worked.

RCM Investigation have proven to be capable of working on multiple major criminal cases simultaneously, with limited supervision. They provide great work product. Using RCM Investigation is comparable to having another attorney on board, especially given that they understand the notion of relevant evidence. I always get effective, ethical, accurate and affordable results.”

"We retained RCM Investigation three years ago to investigate a troublesome case file. As a result of our ongoing case file, RCM Investigation has worked with our attorney to help defend us and has given reassurance they will go to the legislator to battle for our small business, its rights, its integrity & justice. Since then, we regularly used RCM Investigation to run background checks of prospective employees & request assistance with multiple unanswered questions. Our information requests are handled accurately & without delay. We have recommended RCM Investigation to our friends and recommend them to you without hesitation."
