Steve W. Berman, Managing Partner

Steve_W_Berman_mediumSteve Berman co-founded Hagens Berman in 1993 and is the firm’s managing partner. He leads the firm’s whistleblower practice, and has represented a number of relators under the False Claims Act. Widely considered one of the most successful attorneys in the country, Mr. Berman also represents consumers, investors, and employees in large, complex litigation in state and federal courts.

In the 1990s, Mr. Berman worked with a whistleblower, former Brown & Williamson executive Jeffrey Wigand, who helped expose Big Tobacco’s knowledge of the dangers of cigarettes. The disclosure of Mr. Wigand’s information ultimately helped lead to a $206 billion settlement on behalf of plaintiffs in 13 states.

Today Hagens Berman represents whistleblowers under a number of statutes, including the federal and state False Claims Acts and programs administered by the Securities and Exchange Commission (SEC), the Commodities Futures Trading Commission (CFTC), and the Internal Revenue Service (IRS).

Berman’s trial experience has earned him significant recognition and led The National Law Journal to name him one of the 100 most powerful lawyers in the nation, and to repeatedly name Hagens Berman one of the top 10 plaintiffs’ firms in the country. Read more »
