Sean Helle

Sean Helle is a supervising staff attorney based in the Washington, D.C. office. He previously worked as a litigator in the Northern Rockies office and as a member of Earthjustice’s Policy and Legislation team.
Before joining Earthjustice, Sean served as a law clerk to Judge Diana E. Murphy, of the U.S. Court of Appeals for the Eighth Circuit, and Judge Ellen Segal Huvelle, of the U.S. District Court for the District of Columbia. And before joining the Washington, D.C. office, Sean had the opportunity to teach in the environmental-law clinics of the University of Colorado and the University of Chicago.
For better or worse — better, probably — his last name rhymes with “jelly.”
