John A. DiLorenzo Jr.
Partner
Co-chair, Government Relations Practice
John DiLorenzo's practice emphasizes change. Even if the law does not support a client's position, there may be good policy reasons to support change to the law. John's practice designs and implements strategies to change the law by lobbying legislative and executive branch officials, initiating administrative rulemaking, or litigating to clarify what the law means. John has authored and been a primary advocate for major legislation in the areas of state and local taxation, tort reform, natural resources, and economic development and environmental insurance recovery. John also assists clients in campaign finance, government ethics, initiatives and referendums, appellate cases, and a variety of government-related litigation matters. In November 2019, John was lead counsel on a trial against the State of Oregon resulting in the largest jury verdict in state history.
