Kristen Boyles is the managing attorney of Earthjustice’s Northwest Regional Office in Seattle, Washington.

For over 25 years, Kristen’s work has focused on conservation issues including Pacific Northwest forestry, Columbia and Klamath River salmon protection, impacts of pesticides on people and the environment, water quality concerns, the national Roadless Rule, and national monuments. She has fought for the protection and recovery of threatened and endangered species — Pacific salmon, marbled murrelets, gray wolves, and others. Kristen continues to fight fossil fuel infrastructure expansion in Washington, Oregon, and British Columbia and is part of the movement for a just transition to a clean energy future.

Kristen is a graduate of Stanford University and Cornell Law School. Prior to joining Earthjustice, Kristen had the privilege of clerking for Judge Raymond J. Pettine in the U.S. District Court of Rhode Island and Judge Robert R. Beezer in the U.S. Court of Appeals for the Ninth Circuit. She also worked as a staff attorney for Pacific Rivers.

In 2017, Kristen received the Sierra Club’s William O. Douglas Award for “outstanding use of the legal/judicial process to achieve environmental goals, particularly those with national significance.” In 2026, the Public Interest Environmental Law Conference in Eugene, Oregon, awarded Kristen the David Brower Lifetime Achievement Award. She remains dedicated to the use of the Oxford comma.
