Attorneys

Over the past five years, the Attorneys at GBB have worked together with whistleblowers to recoup more than $5 billion to the federal and state governments. In addition, GBB attorneys have worked with their whistleblower clients to secure recoveries against some of the nation’s largest pharmaceutical, major energy, health care, and defense contracting corporations. Firm counsel have litigated under both the Federal and state False Claims Acts as well as the Securities and Exchange Commission (SEC) and Internal Revenue Service (IRS) whistleblower programs.

As a boutique high-impact law firm, GBB brings a unique blend of expertise to its cases.
