Jeff Trevillion is a director in the firm’s Oklahoma City office assisting clients as a member of the Taxation Practice Group. An experienced trial lawyer and certified public accountant, Jeff develops comprehensive strategies for clients facing civil and criminal tax controversies, litigation, and federal criminal defense. He also focuses his practice on highly regulated industries, and routinely represents clients before numerous law enforcement and regulatory agencies including, the U.S. Department of Justice (DOJ), the U.S. Attorney’s Offices, the Internal Revenue Service (IRS), the Oklahoma Tax Commission, and the State Attorney General.
His extensive knowledge of U.S. tax law and civil tax procedure allows him to provide clients with invaluable representation in all phases of federal civil tax controversies regarding sensitive matters and bet-the-company cases. Jeff defends investigations conducted by the IRS Criminal Investigation Division (CID) and grand jury proceedings. He also defends civil tax suits by the DOJ Tax Division and criminal prosecutions by U.S. Attorney’s Offices, and advises clients with sensitive “eggshell” audits that could potentially result in a criminal referral to the DOJ.
Active in the community, Jeff has served on the board of directors or as a trustee for several legal organizations including, the Oklahoma County Bar Foundation, the Oklahoma City Association of Black Lawyers, the OBA Young Lawyers Division, and currently serves as the Past Board President of the Oklahoma Bar Foundation.
