William M. Treanor is the Executive Vice President of Georgetown University, Dean of the Law Center, and Paul Regis Dean Leadership Chair. Treanor joined Georgetown in 2010 and was reappointed to serve a third term as Dean and Executive Vice President on July 1, 2020.

Under Treanor’s leadership, Georgetown Law has hired 75 new faculty members; tripled the number of experiential offerings for students in its clinical, externship, and practicum programs; transformed its law and technology offerings into a world class program with 19 full-time faculty experts and over 80 courses in this area; and experienced its most successful era of fundraising, culminating in nearly $67 million in giving in the last fiscal year.

Treanor has also advanced Georgetown Law’s commitment to affordability and access. During his tenure, Georgetown has more than doubled financial aid; raised nearly $25 million dollars for the Law Center’s scholarship program for exceptional students with significant financial need; and launched the RISE program, which provides academic support for students from historically underrepresented groups. The Law Center also created the Early Outreach Initiative, which brings the Law Center’s dean of admissions, current law students, and alumni together to encourage students in underserved high schools to consider pursuing careers as lawyers.

In keeping with Georgetown Law’s motto, “Law is but the means; justice is the end,” Treanor has focused on increasing opportunities for students to pursue careers in public interest law. He is proud that nearly 1 in 4 graduates move straight into public service jobs – a ratio higher than any other top law school in America. The Law Center supports post-graduate fellowships that have enabled more than 400 graduates to work in public interest jobs, and, in combination with the law firms ArentFox Schiff and DLA Piper, it has launched the D.C. Affordable Law Firm, a “low bono” law firm where recent Georgetown Law graduates provide legal representation to people of limited means.

The National Jurist magazine has named Treanor one of the most influential people in legal education five times. He is a member of the Morristown (N.J.) High School Hall of Fame. In 2020, he was elected into the American Academy of Arts & Sciences for law and education. Most recently, he was selected for the inaugural Honorable Robert A. Katzmann Award for Academic Excellence by the Burton Awards.

Treanor’s areas of academic expertise include constitutional law, property law, criminal law, intellectual property, and legal history. At Georgetown Law, he has taught a first-year legal justice seminar, an upper-level course on the drafting of the U.S. Constitution, and leadership courses. His writings have principally been in the area of constitutional history, and he has been recognized as one of the 10 most-cited legal history scholars in the United States by the University of Chicago Law School’s Brian Leiter. His early work largely focused on the history of constitutional protections of private property. His article “The Original Understanding of the Takings Clause and the Political Process,” 95 Colum. L. Rev. 782 (1995), was recognized by the Land Use Professors Blog as the most cited land use article of the past 30 years. Treanor’s article, “Judicial Review before Marbury” was cited in the Moore v. Harper (2023) majority opinion written by Chief Justice Roberts. His recent article, “The Case of the Dishonest Scrivener: Gouverneur Morris and the Creation of the Federalist Constitution,” examined the changes that Gouverneur Morris and the Committee of Style made in preparing the Constitution’s final draft. W.W. Norton will publish his upcoming book, Fathers of the Constitution: Triumph, Tragedy, and the Creation of the American Republic.

Before coming to Georgetown, Treanor was Dean and Paul Fuller Professor of Law at Fordham Law School. He also served in a variety of positions in the government, including Deputy Assistant Attorney General in the Office of Legal Counsel, U.S. Department of Justice; Associate Counsel, Office of Independent Counsel during the Iran/Contra investigation. He was law clerk to the Honorable James L. Oakes, U.S. Court of Appeals for the Second Circuit. Treanor has a Ph.D. in history from Harvard University, a J.D. from Yale Law School, and a B.A., summa cum laude, from Yale College.
