Our attorneys have expertise in litigation under the False Claims Act, employment, environmental, corporate governance actions, complex commercial litigation and other common law rights of action. Firm attorneys include former prosecutors, law professors, a Presidentially Appointed member of the United States Occupational Safety and Health Review Commission, former large firm defense counsel, and an attorney who is licensed to practice medicine.

GBB Attorneys have earned their reputation in high stakes litigation representing whistleblowers under the False Claims Act in cases resulting in the recovery of $6 Billion for Federal and State governments. They have litigated cases that have driven regulatory and legislative reform, including rules to protect school children against exposure to asbestos and legislation to compensate nuclear weapons workers who have contracted a dread disease.
