Oklahoma Policy Institute announced today that David Blatt, its longtime Executive Director, will leave the organization later this year. Blatt intends to remain with the Tulsa-based think-tank through the transition process to a new Executive Director. “We are extremely grateful to David for the great success he has had in building OK Policy into an organization that is widely recognized and respected for its quality, credibility, independence, and integrity,” said Don Millican, who serves as OK Policy’s Board Chair.
