Matthew Preusch practices in Keller Rohrback’s nationally-recognized Complex Litigation Group. 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.

Matthew is passionate about protecting 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 to hold the responsible manufacturers accountable. Working on behalf of government entities, including the State of Oregon, Matthew has investigated or is litigating claims related to PCB contamination and the opioid epidemic.
