Matthew Preusch
Partner
Matthew Preusch is a partner at Keller Rohrback and practices in its nationally-recognized Complex Litigation Group.
Matt focuses his work on cases that protect people and the environment. He has helped initiate landmark consumer litigation related to Volkswagen’s “Clean Diesel” deceit and Wells Fargo’s unauthorized account scheme. When studies of moss samples in trees in Portland, Oregon identified several pollution “hotspots” in that city, he and others at Keller Rohrback launched cases on behalf of residents that resulted in the largest environmental class action settlement in Oregon history. More recently, he served as co-lead counsel representing survivors of four utility-caused wildfires in Oregon. That case resulted in a historic, first-of-its-kind jury verdict finding a utility liable to a class for punitive damages. In addition, Matt serves as individual plaintiffs’ Liaison Counsel for the Marshall Fire litigation in Colorado.
Before joining Keller Rohrback, Matthew served as an honors attorney in the Oregon Department of Justice’s appellate and trial divisions. He was a judicial extern for the Hon. Michael W. Mosman in the District of Oregon during law school. Prior to his legal career, he spent 10 years as a journalist in the Pacific Northwest, covering regional and national news for The Oregonian, The New York Times and other publications.
