A top-tier litigator who has served in all three branches of the U.S. government, Steve has played a pivotal role in resolving some of the most complex and contentious issues in environmental, natural resources, and energy law in both the public and private sectors for more than 25 years, and is a nationally recognized subject-matter expert with a proven track record in the courtroom stemming from his successful handling of literally hundreds of cases

Steve is a litigation partner and senior member of the firm’s Regulatory and Government Controversies practice group, based in the Portland Office. He joined Marten following a distinguished career as an Assistant U.S. Attorney in the District of Oregon, where he successfully handled many of the district’s most consequential and controversial environmental disputes during the last two decades, in cases involving resources and issues ranging from timber, water quality and use, developed recreation, and transportation, to grazing, protected species, wetlands, and energy (encompassing production, transmission, and rate-setting) matters. Steve has also handled cases and been at the forefront of various initiatives addressing highly sensitive environmental issues throughout the country, with a principal focus on those in the West. This, combined with the fact he is a native Westerner, provide Steve with virtually unparalleled knowledge of the unique array of legal and policy issues related to management of natural resources and public lands in the region.
