Bill Martin’s nearly two decades of government and private practice experience enables him to guide financial services companies, blockchain and other fintech companies, audit and special committees, officers and directors, and others in connection with internal investigations, government and regulatory inquiries and enforcement actions, and litigation.

A former senior counsel in the US Securities and Exchange Commission’s Market Abuse Unit, Bill has investigated and prosecuted securities cases involving insider trading, market-structure practices, the Foreign Corrupt Practices Act (FCPA), failure to supervise, investment advisors, and cybersecurity. In these matters, Bill worked closely with the Justice Department, FBI, IRS, FINRA, and other regulators.

Before entering public service, Bill spent six years in the litigation practice of a major New York law firm, advising clients in shareholder derivative and securities litigation and investigations. He frequently advised on cross-border matters and on litigation involving accounting fraud, internal controls, and other issues connected to the FCPA.
