Stacey’s practice focuses primarily on antitrust and other commercial litigation, with an emphasis on handling complex legal and factual issues that require careful research, analysis, and strategy. In her more than ten years of trial practice, she has litigated antitrust cases involving claims of price- and supply-fixing, group boycott, exclusive dealing, tying, monopolization, and conspiracy. In addition, she has handled contractual and business tort disputes and suits involving Lanham Act, RICO, ERISA, and federal tax claims. Stacey’s clients include Fortune 150 corporations and other major companies in a variety of industries, such as petrochemical, petroleum, telecommunications, grocery, agriculture, and health care.
