Kathy O’Neill, former senior director of investigations and litigation at the US Department of Justice Antitrust Division – the division’s highest career civil enforcement position – has joined Cooley’s Washington, DC, office as a partner in the antitrust & competition practice group.
In her role at the DOJ, O’Neill oversaw every civil investigation and litigation initiated by the Antitrust Division, helped to pioneer a robust approach to antitrust enforcement pursuing cutting‐edge legal theories, and played a key role in developing agency enforcement policy.
Before joining the Antitrust Division, O’Neill served as assistant attorney general to the New York attorney general and as an attorney adviser at the Federal Communications Commission. O’Neill joins Cooley with more than two decades of government experience.
“The antitrust enforcement environment is red-hot in the US and across the globe, with high tech and life sciences directly in the crosshairs,” said Jacqueline Grise, chair of Cooley’s antitrust & competition practice group. “Cooley provides highly sophisticated antitrust services to advance the success of our clients’ most imperative business strategies, and with the addition of Kathy, we expand our ability to take on any antitrust challenge on behalf of our innovative client base.”
