While serving in the Jesuit Volunteer Corps, Jim began advocating for nuclear disarmament as a member of the Bethlehem Peace Pilgrimage. He spent the next quarter century investigating radioactive pollution from the production and testing of nuclear weapons, mostly focused on the Hanford Site in south-central Washington State. This included working as a paralegal for the plaintiffs in the Hanford downwinder litigation.

Interwoven with his Hanford-related positions, Jim directed life, justice and peace ministry for the Diocese of Spokane, the Archdiocese of Seattle, and the Washington State Catholic Conference. He has a master’s in religious studies from Gonzaga University. Jim continues to advocate for disarmament with local and national organizations. He lives in Seattle with his wife and daughter.
