Martha Dina Argüello

Executive Director

For the past 32 years, Martha has served in the non-profit sector as an advocate, community organizer, and coalition builder. She joined PSR-LA in 1998 to launch the environmental health programs, and became Executive Director in November 2007. She is committed to making the credible voice of physicians a powerful instrument for transforming California and our planet into a more peaceful and healthy place.

Martha grew up in the Pico-Union area of Los Angeles. At the young age of 14, she made a lifelong commitment to effect social change after seeing her friend killed by a school security guard. While working as a health educator in the 1990s, Martha had an epiphany — she realized that although early detection can prevent death from breast cancer, it does not prevent breast cancer, which has been increasingly linked to the exposure of environmental toxicants. Since that realization, Martha has dedicated her career to the environmental justice movement, and has lectured nationwide on the use of precautionary principle policies.

As a coalition builder, Martha has emphasized the need for local grassroots advocacy working in partnership with statewide policy actions. She is an active board member of numerous organizations, including Californians for Pesticide Reform, the California Environmental Rights Alliance, and Californians for a Healthy and Green Economy. She also co-founded the Los Angeles County Asthma Coalition and the Coalition for Environmental Health and Justice, and was appointed to Cal/EPA’s Environmental Justice Committee and the California Air Resources Board’s Global Warming Environmental Justice Advisory Committee.

Denise Duffield

Associate Director

Denise Duffield joined PSR-LA in 2004. She serves as PSR-LA’s administrator and directs its nuclear threats program, which advocates for health protective policies related to nuclear weapons, nuclear energy, and radiation regulations. Denise developed PSR-LA’s Peace and Security Ambassador program and coordinates public awareness events, physician and health professional training, legislative advocacy, and media placement related to nuclear issues. She works to develop joint strategies and initiatives with allied national and state nuclear watchdog, peace, environmental, public health, and justice organizations.

Denise also works on environmental health and justice issues, particularity on addressing the needs of local communities who are impacted by toxic contamination and the failure of regulatory agencies to protect them. Denise leads PSR-LA’s efforts to ensure a proper cleanup of the Santa Susana Field Laboratory, a former nuclear and rocket testing facility that is highly polluted with radiological and chemical contamination. She also participates in the Peoples Senate, a statewide collaborative that combines grassroots organizing in highly impacted communities with strategic policy advocacy.

The project works to promote good health for its participants through access to fresh produce, the exercise offered by gardening, and educational workshops.
