Edward T. Decker

I believe that understanding my clients’ businesses is the key to providing effective and proactive advice. One of the most rewarding parts of my practice has been learning the unique nuances of how my clients do business—whether that story is how the client executes an IPO, syndicates bonds, or makes solar panels.

About Edward

Edward Decker counsels companies, financial institutions, and individuals in disputes with other companies, government regulators, and class-action plaintiffs. Edward has experience representing clients in complex commercial matters, ranging from antitrust and securities class actions to corporate governance, M&A, and contract disputes. He also regularly represents clients, including banks and broker-dealers, in responding to investigations conducted by the Department of Justice, Federal Trade Commission, Securities and Exchange Commission, FINRA, and other regulators covering a range of substantive topics, including anticompetitive conduct, corporate scandal, bribery, and financial crimes.

In addition to counseling clients already involved in disputes, Edward advises clients on pre-dispute risk management, including advising on the antitrust components of contemplated transactions, developing policies and procedures to ensure best practices, and running internal investigations in response to possible employee misconduct.

Before joining Miller Nash, Edward practiced as a litigation associate in the New York office of Shearman & Sterling LLP.
