Insurance, Legal & Corporate Investigations Firm
Trusted investigative services since 1991
R&D Investigations is a highly respected private investigation agency known for quickly and effectively gathering accurate intelligence for its insurance, legal, and corporate clients. Each of our private investigators is licensed, insured, and carefully trained to manage each case with professionalism, discretion, and strong ethical standards.
Our firm was founded in 1991 by Don Dunn after he spent decades investigating exaggerated and fraudulent insurance claims. Today, R&D Investigations is owned and operated by Don’s daughter, Bri (Dunn) O’Neill, and Ryan Buhl, a long-time R&D investigator. We continue to support clients with the same level of care and attention we have long been known for.
When you work with R&D, you’re not just hiring an investigator. You’re hiring a team that takes your case seriously and shows up ready to get it right.
