Roger Lewis is a Principal in the firm’s Litigation Group. He focuses his practice on False Claims Act litigation, representing whistleblowers of all kinds in investigating, evaluating and filing claims against persons or entities that defraud the United States government, state government, or other public and private entities. Since Roger joined Goldberg Kohn's False Claims Act practice, the firm's cases have returned more than half a billion dollars to state and federal treasuries.  

Roger also litigates complex commercial litigation in the state and federal courts and before administrative agencies. He has handled cases in Illinois, Ohio, Pennsylvania, Florida, New York, California, North Carolina, Michigan, Wisconsin, Texas, Missouri and Kansas. In addition to general commercial contract and tort matters, his cases have involved lending and financial institution litigation, consumer and property tax litigation, and partnership and shareholder issues. His property tax litigation experience includes one of the biggest valuation trials in the history of the Illinois Property Tax Appeal Board, representing the owner of the state's largest nuclear generation facility.  

He has extensive experience in protecting the rights of secured creditors in bankruptcy and insolvency litigation in courts nationwide. As lenders increasingly use all of the tools in their toolbox to exercise their rights in collateral, Roger' practice has been on the cutting edge of validating and securing those rights in court.

Roger aggressively pursues litigation objectives within the framework of the client's broader goals, counseling clients thoughtfully and rigorously through their most complex, high-stakes matters.
