Mark Miller

Mark Miller directs litigation and policy for Pacific Legal Foundation’s Environment & Natural Resources (ENR) practice group, advancing an abundance-first legal narrative that defends Americans’ right to use land and resources as a matter of right, not by agency permission. He has served as lead or second-chair counsel in three unanimous wins at the U.S. Supreme Court protecting landowners from government overreach.

Before leading the PLF ENR team, Mark served then-South Dakota Governor Kristi Noem as general counsel and later chief of staff, directing constitutional litigation strategy and managing the machinery of state government to ensure executive action stayed within constitutional bounds and statutory authority.

In 2025, Florida Governor Ron DeSantis appointed him to the Florida Commission on Human Relations, where he serves as chair, presiding over statutory enforcement of Florida’s civil rights laws. He previously served on a Florida appellate Judicial Nominating Commission appointed by then-Florida Governor Rick Scott.

Mark serves on the Board of Trustees for the University of Florida College of Law, his law school alma mater. He also serves on the board of Farm of the Child USA, a non-profit organization that supports Finca del Niño, a Catholic orphanage and school in Honduras that provides housing, education, and long-term care for children in need.

Early in his career, Mark apprenticed as an elbow law clerk for both United States District Court Judge Henry Lee Adams Jr. of the Middle District of Florida and Judge Emerson R. Thompson Jr. of Florida’s Fifth District Court of Appeal in Daytona Beach.

A double Gator with degrees from the University of Florida and UF Law, Mark lives in South Florida with his wife, Mindy, a Catholic school principal. They are the proud parents of two UF grads like their dad, and two Notre Dame Golden Domers like their mom.

Mark is admitted to practice law in Florida and New Jersey.
