San Francisco – Sidley is pleased to announce that David L. Anderson and Sheila A.G. Armbrust have rejoined the firm as partners in its San Francisco office after serving as the U.S. Attorney and Assistant U.S. Attorney for the Northern District of California, respectively. Mr. Anderson and Ms. Armbrust are members of the firm’s White Collar: Government Litigation and Investigations practice.
Productivity soared at the U.S. Attorney’s Office under Mr. Anderson’s leadership. Criminal filings rose across all case categories with a special focus on public corruption, corporate fraud, economic espionage, and organized crime. In numerous public appearances as U.S. Attorney, Mr. Anderson emphasized the importance of professional law enforcement to the safety of the community and the rule of law.
“We are thrilled to have Dave return to Sidley now that he has finished his tenure in the U.S. Attorney’s office,” said Sharon Flanagan, managing partner of Sidley’s office in San Francisco and a member of the firm’s Management and Executive Committees. “As one of the nation’s leading trial attorneys, we welcome him back to the firm.”
Prior to his appointment as U.S. attorney, Mr. Anderson was a partner at Sidley with a far-reaching trial practice. Throughout his career, he has successfully tried challenging cases including complex securities fraud and intellectual property cases. His clients have ranged from leading cellular carriers and large financial institutions to individuals targeted in criminal, SEC, or other investigations.
Earlier in his career, Mr. Anderson was the First Assistant U.S. Attorney in the Northern District of California and an Assistant U.S. Attorney. At the outset of his career, he clerked under former Supreme Court Justice Anthony Kennedy; for the Honorable J. Clifford Wallace of the United States Court of Appeals for the Ninth Circuit; and the Honorable George H. Aldrich of the Iran-United States Claims Tribunal in The Hague, Netherlands.
While at the U.S. Attorney’s office, Ms. Armbrust was part of the corporate and securities fraud section with an emphasis on investigating and prosecuting crimes affecting the safe delivery of healthcare, including mail and wire fraud, securities fraud, violations of the FDCA, trade secret theft, trademark violations, computer fraud and abuse, money laundering, and drug trafficking. She was also chair of the criminal division hiring committee where she led the hiring of more than 30 attorneys in 18 months.
Ms. Armbrust was an associate at Sidley prior to joining the U.S. Attorney’s office working on a range of litigation matters including white-collar defense and investigations primarily for healthcare and life sciences clients. She also has considerable experience in both cyber and trade secrets investigations.
“Sheila was a rising star at the firm before she joined the public sector,” added Sharon. “With her trial experience and further developed investigations skills, we know she will be a highly valued resource to our clients.”
