What we do

We represent whistleblowers for the same reasons that courageous men and women come forward to expose wrongdoing, injustice, or cheating: we believe in accountability, justice, and fairness, whether that’s for taxpayers, investors, consumers, competitors, or the government.

Our Clients Trust Us

Whistleblowing can be a stressful process stretching over many years. Our clients often work for many years to effect change before they call us. From our first conversation, we’ll listen to your story. If we work together, our team of whistleblower lawyers will be at your side with support and expert legal guidance at every turn – through government investigations, legal filings, settlement, or litigation if necessary. All along the way, we’ll help you understand what to expect and the best legal avenues for you and your case.

WHISTLEBLOWER LAWYERS
WITH
DEEP EXPERIENCE AND INTERNATIONAL SCOPE

Our clients come to us because they can’t stay silent about wrongdoing such as corporate fraud, false claims, overcharging, cheating, investor deception, price fixing, kickbacks, bribery, defective products, and tax evasion.

Our cases arise from business and industry, as well as those working with government contractors. Our cases come from within the United States and overseas. In our globalized world, international wrongdoing falls under U.S. whistleblower statutes when companies do business in the United States, are traded on U.S. stock exchanges, or have government contracts. Our team works coast to coast and internationally, with a full-service London office. We can communicate across 17 languages.

Clients come to us because they know that we have a track record of working closely with government attorneys, agents, and investigators. We make sure that the right federal and state government officials clearly hear our clients’ stories, and that those officials know that they can rely on our attorneys and our clients for the kind of reliable information and analysis that’s needed for a successful outcome.

We take on whistleblower cases of all types, characteristics and sizes. And our clients range from minimum-wage earners to management. Each case is important to us.

Making a Difference

During the last two decades, our committed whistleblower lawyers have recovered more than $350 million in awards for whistleblowers. Monetary rewards for whistleblowers arise from the recognition that whistleblowers often put their careers and livelihoods on the line to expose wrongdoing, and should be compensated for their role in recovering funds for the government, taxpayers, investors and others.
Whistleblowers come to us because we understand the complicated, constantly changing landscape of state and federal whistleblower laws. We have a proven track record of working closely and effectively with state and federal governments on behalf of our clients. We bring to our cases the kind of resources and staying power that government sometimes can’t.
As whistleblower lawyers, we have successfully represented clients under the False Claims Act and whistleblower laws that apply to the Internal Revenue Service, Securities and Exchange Commission, the Commodity Futures Trading Commission, as well as state statutes and other programs.
