Sarah R. LaFreniere

Sarah is an associate in Hausfeld’s Washington D.C. office focusing on complex litigation and antitrust enforcement. Sarah represents clients in litigation for harm suffered throughout the world, using innovative solutions to provide exceptional advocacy. Sarah has been awarded the American Antitrust Institute’s award for Outstanding Antitrust Litigation Achievement by a Young Lawyer for her work in In re Foreign Exchange Benchmarks Rates Antitrust Litigation. That case has secured over $2.3 billion in settlement funds for class members who allege the world’s largest banks conspired to manipulate the foreign exchange market.

In addition to her work on the Foreign Exchange matter, Sarah represents the interests of European consumers seeking damages from Volkswagen AG in relation to that company’s massive “clean-diesel” fraud. Sarah has been at the forefront of litigation pursuant to 28 U.S.C. § 1782, seeking to obtain evidence through U.S. discovery mechanisms for use in the European litigation. In addition, Sarah’s recent representative matters include:

  • Representing specialty-film exhibitors in various metropolitan markets who collectively allege a nationwide theater chain abused its national circuit power;
  • Representing a whistleblower in a qui tam action alleging medicare and Medicaid fraud;
  • Representing a leading software manufacturer in copyright-infringement litigation against the federal government;
  • Negotiating a favorable settlement for a royalty-rights holder in the college athletics space;
  • Submitting an amicus brief in the Ninth Circuit Court of Appeals arguing Idaho’s “ag-gag” laws violated the First Amendment.

Sarah graduated summa cum laude from American University Washington College of Law. After law school, Sarah worked as a judicial law clerk to the Honorable Victor J. Wolski on the United States Court of Federal Claims. In addition to her studies at the Washington College of Law, Sarah obtained a J.D. from the University of Ottawa.
