Lin Kahn has more than a decade of experience defending against and prosecuting antitrust matters in private practice and public service. Lin recently spent five years at the Federal Trade Commission (FTC), where she served as lead litigation and trial counsel in the agency's successful price-fixing and anticompetitive conduct lawsuit against major players in the dental industry. During her tenure at the FTC, she also led a number of merger investigations in industries such as technology, pharmaceuticals, consumer products, and health care.

Lin helps clients navigate high-stakes antitrust litigation, merger review, and government investigations. Drawing on her experiences as a first-chair trial lawyer and former government enforcer, she has led clients through claims arising from a broad range of issues, including conspiracies to eliminate nascent competition, no-poach agreements, monopolization, group boycotts, killer acquisitions, and vertical merger challenges. Lin was one of only five antitrust lawyers in the country to receive the honor of "Top Attorneys Under 40" from Law360 in 2021.
