Cullen Investigations is a full-service licensed and bonded private investigations agency based in Tulsa, Oklahoma. We offer a wide array of investigative & consulting services, including domestic relations (custody, infidelity), background checks, crisis management, complex litigation, and criminal defense investigation from pre-filing to post-conviction relief and death row appeals.

Owner Eric Cullen and his team of investigators are nationally recognized for delivering effective, honest results. Cullen's work has led to the exoneration of seven wrongly convicted Oklahomans who would have spent the rest of their lives in prison. He's been featured on Dateline NBC, Washington Post, and the podcast "Wrongful Conviction with Jason Flom", among others. In 2019 he was named a Tulsan of the Year by the Tulsa World.
