Linda Chatman Thomsen
Ms. Thomsen, who was the first woman to serve as the Director of the Division of Enforcement at the Securities and Exchange Commission, is a partner in Davis Polk’s Litigation Department and practices in the Washington DC office. Her practice concentrates in matters related to the enforcement of the federal securities laws.
She has represented clients in SEC enforcement investigations and inquiries, in enforcement matters before other agencies, including the Department of Justice (various U.S. Attorneys Offices) and the Commodities Futures Trading Commission, in investigations and inquiries from self-regulatory agencies, including FINRA, and in internal investigations.
These matters, which are typically nonpublic, have covered a broad range of securities-related subject matters, including insider trading, foreign corrupt practices, financial reporting, manipulation and regulatory compliance. Her clients have included major financial institutions, regulated entities, public companies and senior executives.
Ms. Thomsen returned to Davis Polk in 2009 after 14 years of public service at the SEC. While there she held a variety of positions and ultimately served as the Director of Enforcement from 2005 through February 2009.
