Donald Klawiter has a career as an antitrust partner at three major international firms and as a prosecutor and senior official at the Antitrust Division of the U.S. Department of Justice. In June 2021, Don joined Sterlington, PLLC, one of the world's leading premium virtual law firms, where he serves corporate and individual clients and continues to contribute to today's lively antitrust debate. Because of Sterlington's structure, the firm can serve clients with great value and efficiency.

Don's practice focuses on antitrust investigations and litigation with primary emphasis on international cartel matters. He has represented accused corporations and executives from six continents. Don has also led corporate internal investigations in cartel and merger matters and advised corporate boards and executives on how to respond to investigations and enforcement actions. He has also developed innovative compliance training for clients. He counsels clients to seek - and obtain -- corporate leniency in the United States and other jurisdictions.

Don's most significant professional achievement was his tenure as chair of the ABA Section of Antitrust Law in 2005-06. He held that office as the international enforcement community came to life and worked aggressively, and the international competition bar responded creatively to this paradigm shift. Don was a founder and a twelve-time participant in the ABA's International Cartel Workshop, the premier cartel enforcement event worldwide.

Don has been a speaker or organizer at antitrust conferences in 18 jurisdictions, and he has testified before the U.S. Senate Judiciary Committee and the U.S. Sentencing Commission. He has written over 150 articles on antitrust issues.
