Colleen Smith, an experienced trial lawyer and Global Vice Chair of the firm’s Securities Litigation & Professional Liability and Public Company & Board Representation Practices, represents emerging and Fortune 500 companies and their officers and directors in high-stakes complex litigation.

Ms. Smith has secured major trial victories for clients facing enterprise-threatening liability, including in the first securities class action to go to trial in over a decade.

Ms. Smith regularly defends companies and their executives against private plaintiffs claiming disclosure fraud, often achieving early dismissals on motion practice.

Representing a technology company CEO in one such matter pursued by the SEC, Ms. Smith helped secure a unanimous defense verdict following a three-week jury trial — a Daily Journal Top Defense Verdict of 2014.

Before becoming a lawyer, Ms. Smith served as a US Naval Surface Warfare Officer on the guided missile destroyer USS Decatur (DDG 73), and was one of the first women to serve in a combatant role. After law school, she served as a law clerk for Judge David R. Thompson of the US Court of Appeals for the Ninth Circuit and Judge James H. Michael of the US District Court for the Western District of Virginia.
