J. William Piereson (Will) first joined Ropes & Gray’s litigation and enforcement practice group as an associate in 2017. He returned to Ropes & Gray in 2021 after completing a clerkship with the Honorable Loretta A. Preska of the United States District Court for the Southern District of New York.
Will’s practice covers a wide range of civil litigation in both federal and state courts—including complex commercial disputes, securities litigation, shareholder and corporate governance disputes, and deal-related litigation—as well as government investigations and enforcement matters. Across those matters, Will represents sophisticated clients such as financial institutions, private equity firms, investment advisers, public companies, and individual officers and directors. Will also maintains an active pro bono practice, representing asylum-seekers in proceedings before immigration courts as well as criminal defendants in trial court proceedings, appellate matters, and in connection with petitions for post-conviction relief.
During law school, Will served for two years as an executive editor of the Harvard National Security Journal. He also interned on Capitol Hill as a law clerk for two United States senators. Prior to attending law school, Will worked at a leading consulting firm in Washington, DC, where he primarily assisted clients in the United States intelligence community in analyzing state and non-state actor use of social media platforms and other emerging technologies.
