The Securities and Exchange Commission has named Mark Cahn deputy general counsel for litigation and adjudication in the SEC’s Office of the General Counsel. In this new role effective next week, Cahn will help oversee enforcement matters, appellate cases, and adjudications.

Cahn fills a position previously held by Andrew Vollmer, who announced last month that he will soon be leaving the SEC to return to the private sector.

Cahn has been a member of the Securities Litigation and Enforcement Practice at WilmerHale, a firm he joined in 1988. He has worked on matters involving public companies, financial institutions, and individuals as well as the SEC, FINRA, and other regulatory bodies. His expertise in securities law and enforcement ranges from financial reporting, accounting, and disclosure issues to supervision matters and internal corporate investigations.
