U.I.S. investigators have extensive experience in the industry and are committed to providing clients with high-quality investigation services. With a focus on delivering accurate and reliable results, United Investigation Services is dedicated to helping its clients find the truth and achieve their goals. U.I.S. provides surveillance and intelligence-gathering solutions for a variety of applications. If you are in a situation where you feel you’re being misled, manipulated, or otherwise put at a disadvantage due to insufficient information, we can help you build a better case, or simply make an informed decision.

By using our professional capacity for surveillance and reconnaissance, we can create a detailed picture of any scenario, empowering you with access to the knowledge required for an informed option. Our access to information on a professional scale enables us with the capability to establish informed solutions that ensure you are getting the best outcomes for your interests.

While we are a resource for a number of solutions requiring a professional scope of information, our firm specializes in criminal defense investigations. We have advanced experience in working with many defense attorneys, acquiring contracts called CSS's through the Office of Public Defense Services (OPDS).
