Bill has represented major corporations in high-stakes litigation for more than 30 years. He has achieved favorable results for clients in state and federal courts across the country, and frequently serves as regional or national counsel for clients facing suits and regulatory actions in multiple venues. He has been recognized as a top litigator by The Best Lawyers in America®.

He is a past Chair of the 60,000-member ABA Section of Litigation, the largest section in the ABA, and a current member of the ABA Board of Governors. Bill is also a member of the American Law Institute, the leading independent organization in the United States that works to improve the law. Bill has been selected as chair of a number of statewide commissions examining critical issues in the practice of law. Most recently, the Supreme Court of Missouri appointed him to serve as the chair of the Commission on Racial and Ethnic Fairness.

Bill's clients vary from major financial institutions to manufacturers to post-secondary institutions. He has litigated cases on behalf of companies facing high-risk litigation and helped businesses manage and respond to large portfolios of litigation in multiple jurisdictions. These matters include highly complex and document-intensive cases involving breach of contract, fraud, corporate governance, insurance coverage, lost profits, lender liability, and tortious interference.

In his work for regional and national clients, Bill and his team have developed an innovative, statistics-based predictive model that evaluates large-scale litigation portfolios and effectively controls costs.
