In the last three terms, she has argued five cases before the U.S. Supreme Court and obtained one summary reversal. Sarah has presented many arguments in federal courts of appeals and state appellate courts. Her cases have run the gamut of substantive areas, including constitutional law—especially First Amendment and separation-of-powers issues—as well as administrative law, arbitration, class actions, antitrust, False Claims Act litigation, commercial litigation, and federal civil procedure. 


Sarah is widely recognized for her appellate advocacy. Chambers USA has recognized her nationally as a leading lawyer in Appellate Law, and reported that clients describe her as “a superb advocate at the Supreme Court,” “very collegial and collaborative,” and “prevails in her arguments.” The Legal 500 reported that Sarah “is brilliant, incisive and collegial.” Law360 ranked her as one of five 2021 “MVPs” in Appellate Law. She has been named to Bloomberg Law’s 40 Under 40 list of top lawyers nationwide and to Benchmark Litigation’s “40 & Under List,” as well as an appellate “Rising Star” by The National Law Journal and Law360, a “Next Generation Partner” by The Legal 500, among Lawdragon’s “500 Leading Lawyers,” and as one of Bloomberg Law’s “Five Fresh Faces to Know in Appellate.” 


Sarah clerked for Justice Clarence Thomas on the Supreme Court of the United States, Judge Laurence Silberman on the United States Court of Appeals for the D.C. Circuit, and Judge Sandra Lynch on the United States Court of Appeals for the First Circuit.  Before joining Williams & Connolly, she served as a Deputy Assistant Attorney General in the Department of Justice’s Office of Legal Counsel.


Sarah received her undergraduate degree summa cum laude from Princeton University, and her J.D. magna cum laude from Harvard Law School. She also holds a Ph.D. and M. Phil. from the University of Cambridge.
