Casselle counsels individuals and entities in high-stakes matters across a variety of sectors and routinely represents clients in connection with allegations of wrongdoing that have enterprisewide implications and the potential for significant reputational harm.
Casselle represents publicly traded and closely held companies in sensitive, high-stakes internal and regulatory investigations and enforcement matters across a broad spectrum of commercial enterprises and industries – including financial services, energy, and health sciences. These matters often involve allegations of corporate malfeasance, professional misconduct, market manipulation, compliance and operational failures, and violation of the federal securities laws.
Casselle takes on matters at every organizational level, ranging from discrete matters involving sensitive allegations made by and about frontline employees to “bet-the-company” matters involving credible allegations of misconduct by officers, directors, and entire divisions of publicly traded companies. In addition to investigating the merits of alleged misconduct, Casselle offers strategic direction to help clients anticipate and mitigate regulatory exposure, develop remediation plans, and strengthen their compliance programs.
A significant aspect of Casselle’s practice involves representing public companies and senior executives in connection with SEC investigations – including recent matters concerning cybersecurity intrusions, SPAC mergers, initial public offerings, and off-channel communications. Casselle also has extensive experience representing major broker-dealers and investment advisers in regulatory investigations involving all facets of their respective operational footprints — including matters arising from routine regulatory exams and more targeted investigations triggered by acute concerns of customer harm.
Casselle is a graduate of Harvard Law School, where she served as president and chaired the governing board of the Harvard Legal Aid Bureau — the nation’s oldest student-run legal services center, and one of the law school’s three historic honors societies. Previously, Casselle was an investigator for the Public Defender Service for the District of Columbia.
