Tom Carpenter is the Executive Director of the Hanford Challenge. He brings decades of experience in organizing, litigating, and policy oversight in the nuclear field, much of it devoted to Hanford. He is an attorney, a graduate of Antioch School of Law, and has a Masters in Organizational Design and Renewal from Seattle University.
Tom worked as the Director of the Nuclear Oversight Campaign for the Government Accountability Project from 1985 to 2007. He founded Cincinnati Alliance for Responsible Energy (CARE) , which challenged plans to open the defect-ridden Zimmer Nuclear Power Plan. Tom also served on the Cincinnati Mayor’s Environmental Advisory Council.
Through his work at GAP and Hanford Challenge, Tom has visited dozens of nuclear sites in the U.S. and Russia, hosted international conferences on protecting nuclear whistleblowers and examining the legacy of highly-contaminated nuclear facilities, and focusing on the Hanford Nuclear Site in southeastern Washington State.
Tom helped establish and is a Board member of the Hanford Concerns Council (and its predecessor, the Hanford Joint Council) to mediate and resolve difficult and complicated issues relating to Hanford.
Tom has represented numerous whistleblowers and workers at various nuclear sites around the nation, including at commercial and military nuclear production facilities, such as Hanford, Los Alamos, Knolls Atomic Power Lab, Pantex, Lawrence Livermore, Fernald, Mound and others. He has authored numerous reports and articles on the effects of nuclear production on workforce health and safety and the environment, and established and participated in independent environmental sampling programs at Hanford, Los Alamos, and Russian nuclear sites.
Liz Mattson, Program Coordinator

Liz is very active on the Hanford Advisory Board (HAB) where she is the chair of the Public Involvement and Communications Committee, encouraging a more strategic approach to public involvement at Hanford. Liz is also involved on the River and Plateau and Tank Waste Committees of the HAB.
Liz helped launch Inheriting Hanford, a regional Hanford mentorship community, empowering young people to become dynamic participants in Hanford cleanup.
She is a strong advocate of working collaboratively to address the problems posed by Hanford. Dealing with decades of contamination will require an intergenerational, multi-stakeholder approach. By building relationships, encouraging openness and trust and working to understand divergent points of view, the broader community of stakeholders will be better equipped to confront the uncertainties and challenges that face remediation efforts.
Liz graduated from Haverford College in 2003, a small Quaker school in Pennsylvania, and has been living in the Northwest since 2005.
