Oklahoma applies the Daubert standard for the admissibility of expert opinion testimony. Oklahoma adopted Daubert in Christian v. Gray.
Economic damages framework
Economic damages in Oklahoma are generally recoverable in personal injury, wrongful death, medical malpractice, product liability, and commercial matters. The recoverable categories typically include past and future lost earnings, lost earning capacity, lost employer-provided fringe benefits, lost household services, and the present value of reasonable and necessary future medical and attendant care.
Methodology that travels
Dr. Pettingill builds his reports around the same methodology in every jurisdiction: U.S. government data sources, peer-reviewed forensic economic literature, and transparent reporting tied to the underlying record. That methodology has survived Daubert and Frye-equivalent challenges across 29 states and the US Virgin Islands — including Oklahoma.
Working with Oklahoma counsel
Whether the matter is venued in Oklahoma state court or in the federal district court for Oklahoma, the engagement process is the same: an initial inquiry and conflicts check, a scope conversation, a written engagement letter, a Rule 26-compliant report, and where required deposition and trial testimony.
