In April 2010, three ConAgra Foods Inc. workers in Chester, Ill., were injured by an explosion in a clogged grain bin they were attempting to clean. Last June, Clifford Law Offices won $112 million of a $179.7 million verdict for two of those plaintiffs from a federal jury in East St. Louis, Ill.

Robert Clifford, founder of the 20-attorney Chicago boutique, started his career with local personal injury legend Philip Corboy. He described the award, which included $67.6 million punitive damages, as "fitting into our top-tier" awards. But he added: "I grew up believing in a full-service model. As big as we are, we’re not above handling my mother’s hairdresser’s case."
