Claudius Modesti

Claudius offers extensive enforcement experience across a broad range of capital market regulatory and corporate governance matters, including representing corporations, accounting and other professional services firms and financial firms before the DOJ, SEC, PCAOB and other regulators. He also conducts internal investigations on behalf of board of directors, audit committees and senior management. Claudius’s practice builds on 25 years of government and regulatory service, including as a DOJ prosecutor, an SEC enforcement attorney and, most recently, as the PCAOB’s first enforcement director. As PCAOB enforcement director, he led investigations of U.S.- and foreign-based accounting firms, many of which involved parallel SEC investigations. He also played a key role in the PCAOB’s collaboration with its foreign audit regulator counterparts.
