"Having managed the Public Defender’s Office in Rockingham County for a number of years, I had the opportunity to work with a large number of private investigators. When I opened my own office and asked other attorneys on who they use for private investigations, they highly recommended Investigative Services. I have now used the “team” that Investigative Services has put together at least a dozen times and remain pleased with the quality of work being done. I know of no other group of private investigators agency in New England that even comes close to providing the depth of knowledge and commitment to follow through that Investigative Services has been able to provide my clients."

"I have been a criminal defense lawyer for over 30 years, and have used the team at Investigative Services on many cases. Not only have I used them to interview witnesses, but they have become part of the defense team in many cases, helping to strategize and reenact events. I often utilize their services as soon as I am involved in a case, to obtain evidence that exonerates my client or creates doubt in the prosecution’s case, which has led to many clients avoiding prosecution all together. Their work has also helped me win cases at trial, and I am always able to rely on the accuracy of their work and their ability to communicate with judges and juries. I highly recommend Investigative Services LLC."
