Her clients value her pragmatic advice and creativity informed by decades of experience navigating them through crisis situations. In court, Carrie leads clients’ defense and overall strategy, particularly as part of joint defense groups, owing to her proven ability to counter complex antitrust theories in some of the largest class actions and multi-jurisdictional cases ever litigated, including seminal cases in the poultry, hospitality, and private equity sectors. Carrie also works closely with clients to secure approvals of proposed transactions from the DOJ and the FTC, as well as favorably and confidentially resolve non-public FTC investigations.
