About me

Mr. Behn was named the first whistleblowers’ “Lawyer of the Year” by the nationwide organization Taxpayers Against Fraud. The group commended Mr. Behn’s “tenacity, management skills and dedication” in  his representation of relators under the False Claims Act. He has also been repeatedly recognized as both a “Super Lawyer” and a “Leading Lawyer” in Illinois. In a profile of his practice, the Chicago Daily Law Reporter described Mr. Behn as “exceptionally able to prosecute highly complex financial frauds,” and quoted one judge as praising him for having “skills not common among litigators.”
