U.S. District Court for the Eastern District of Virginia, Judge Claude M. Hilton

Will joined Becket as Counsel in 2019. Since joining Becket, Will has drafted briefs supporting a faith-based foster agency defending its ministry in the Supreme Court of the United States (Fulton v. City of Philadelphia), argued before the Supreme Court of Texas on behalf of a diocese defending its right to speak transparently about its clergy (Diocese of Lubbock v. Guerrero), successfully defended Orthodox Jewish schools and synagogues against discriminatory lockdown orders, and assisted litigation on all manner of religious exercise nationwide.

Prior to joining Becket, Will practiced law at two international law firms, Shearman & Sterling LLP and Hunton & Williams LLP (now Hunton Andrews Kurth LLP). While in private practice, Will successfully argued on behalf of a major oil and gas company protecting its intellectual property in the U.S. Court of Appeals for the Fifth Circuit, a major paint company protecting its confidential information in an FTC-challenged merger in the U.S. District Court for the District of Columbia, second-chaired a complex commercial arbitration, and handled critical motions and jury preparations in a successful trade-secrets trial in Cook County, Chicago, where his client received a $44 million damages award. He also served as the principal brief writer and/or counsel of record on behalf of international businesses, business leaders, current and former Governors, a U.S. Senator, U.S. Congressmen, high-profile law professors, and religious non-profits in an array of prominent Supreme Court and federal appellate court cases—often raising First Amendment or other constitutional questions. His brief on behalf of the National Catholic Educational Association in St. James School v. Biel was cited six times by nine Ninth Circuit judges disagreeing with the Ninth Circuit’s decision.

In addition to his private-practice experience, Will served as a law clerk to Judge Janice Rogers Brown of the U.S. Court of Appeals for the D.C. Circuit and Judge Claude M. Hilton of the U.S. District Court for the Eastern District of Virginia. He also was an attorney-advisor to an administrative law judge at the U.S. Department of Labor. Will’s writing experience includes a book chapter co-authored with a former member of Congress, and articles on constitutional law and policy appearing in the Catholic University Law ReviewNational AffairsLaw & LibertyForbesNational Review OnlinePublic Discourse, The Washington Post, First Things, and other outlets. During law school, Will served as a research and teaching assistant to Professor Mark Rienzi—thereby aiding numerous religious liberty and First Amendment cases and articles—and is regularly invited to speak on matters of constitutional law.

Will lives in Maryland with his wife and children. They enjoy sailing on the Eastern Shore, spending time with close friends and family, and cheering on their favorite baseball teams.
