Before that, Mr. Strickland served as US Attorney for Colorado, where he led the federal investigation of the Columbine shootings. His substantive expertise includes natural resources and environmental law, health care regulation, and securities law.

“WilmerHale is the perfect fit for me because it has the full range of top policy, regulatory and litigation practices necessary to assist clients with high-stakes matters involving government oversight and policy,” said Mr. Strickland. “I had the privilege of working with a multi-disciplinary team at WilmerHale when I was with UnitedHealth, and was greatly impressed with the firm’s quality and depth, collaborative approach, and sophisticated understanding of how government works.”

Mr. Stricklandearned his BA in English literature, with honors, from Louisiana State University in 1974 and received his JD, with honors, from the University of Texas School of Law in 1977.
