Arizona’s Private Detective

tucson, Arizona court house

Inter-State has been in business for over 29 years and we are proud to say we have an A+ rating from the Better Business Bureau. We are licensed and insured.

Since 1994 we’ve helped countless clients resolve their personal or legal matters with efficiency, accuracy, and empathy. Because we value the privacy of our clients greatly, our investigations are always conducted with the utmost privacy and discretion in mind.

Inter-State is staffed with an eclectic mix of male and female investigators with backgrounds in law enforcement, science, accounting and even licensed realtors. We also have Spanish-speaking investigators if your case warrants such a service. All investigators are experienced and receive continuous training.

We are a team of Arizona private investigators that handles cases not just state-wide, but across the nation as well. We maintain a vast network of trusted vendors and investigators across the country and therefore have the capacity to, and frequently do, perform investigations in different states.

We also have access to many records in Mexico and other countries throughout the world, and travel to other locations as needed.
