Brianne Kucerik

Brianne has extensive experience obtaining regulatory clearance for complex, cross-border transactions and is regularly recognized among the top U.S. antitrust practitioners by Global Competition Review, Legal 500 for Antitrust: Merger Control (2018-2024), and Who’s Who Legal for Competition (2018-2024). In addition, Brianne has been consistently recognized by LMG Life Sciences as a “Leading Life Sciences Lawyer” (2022-2024) for her work representing pharmaceutical and medical device companies. She counsels clients on all aspects of the antitrust merger review process, including advising on antitrust risk, working with economic experts, negotiating remedies where necessary, coordinating with local counsel outside the United States, and advising on due diligence information exchange and pre-closing integration planning. Most recently, Brianne played a lead role in securing antitrust clearance for a number of multi-billion dollar transactions involving well-known pharmaceutical, medical device, retail, hospitality, and private equity clients.

Brianne also has undertaken significant work for clients involved in antitrust government investigations and litigation, including persuading the antitrust enforcement agencies not to bring enforcement actions in non-merger matters and securing dismissal for clients in private antitrust class action litigations.

Brianne is described by clients as an advisor with a “great deal of business acumen” who “offers top notch client service” and the “ability to bridge the regulatory requirements with [clients’] business objectives.” The multi-faceted nature of Brianne’s work, combined with her creative, technical, and strategic expertise earned her a spot on Global Competition Review’s “Women in Antitrust 2021,” a select list of the world’s foremost female leaders in antitrust and competition law. Additionally, she has been named to Lawdragon 500’s “Leading Global Antitrust & Competition Lawyers” list and to its “Leading Litigators in America” guide which recognizes “all-star litigators” from across the U.S. Previously, Brianne was recognized as a “D.C. Rising Star” by the National Law Journal on a list of “game-changing” attorneys aged 40 or under practicing in Washington, D.C. who have “wielded great influence in their practice areas in the D.C. area and beyond.”

Prior to law school, Brianne was a paralegal at the U.S. Department of Justice Antitrust Division, where she worked on merger and non-merger investigations in the telecommunications and media industries.
