Calvert Law Firm is not your ordinary "boutique" law firm. While the firm's attorneys prefer to keep the client list small, they do things in a big way. Led by founder Randall Calvert, the firm challenged oil giant Shell in 2008 - and won a $66.8 million verdict for two Oklahoma families that had not been paid royalties for oil drilled on their land since the 1920s. The firm's lawyers helped an Indian tribe acquire an $80 million horse racing track and casino from a bankruptcy estate. They also recovered more than $2 million in investment losses for 19 individuals as the result of investment adviser misconduct.
