Costello Law Firm represents corporations and their executives facing external legal crises such as litigation or government investigations, and internal crises such as complaints of sexual harassment, theft, whistleblower claims, fraud, or non-compliance with government regulations. We conduct independent internal investigations and prepare reports of findings. We also provide risk management and compliance services designed to avoid future legal crises altogether. Our clients include:


We work with in-house counsel needing experienced litigation and trial support or facing potential conflicts of interest during government investigations, employee complaints and employee malfeasance investigations.


Our attorneys frequently work with large law firms representing corporations during government investigations. We represent company executives and employees, or serve as pool counsel for government witnesses. We also provide trial first chair and second chair services and trial consultation services to outside counsel.


Costello attorneys work with C-Suite Executives during litigation, government investigations, or city, state or federal enforcement actions. We also help executives build internal systems to ensure compliance with all business, employment and other regulations to help avoid the risk and cost of litigation and government investigations.


We often work with Boards of Directors when they need counsel for the board or individual members during investigations, litigation, and/or when they need counsel as a result of potential civil or criminal liability for decisions related to their work on behalf of their corporation.
