Greenaction Mourns the Passing of Marie Harrison

Greenaction Board of Directors

Our board is made up of grassroots leaders from communities on the frontlines of the movement for healthy communities and environmental justice. We have a dynamic, dedicated, and diverse board that guides our organization’s work and helps keep us accountable to the communities we work with and for.


Maricela Mares-Alatorre
Community Organizer/ Policy advocate |

Maricela Mares-Alatorre has joined our Board of Directors after serving on our staff as a Community Organizer and Policy Advocate with Greenaction for 12 years. Maricela is also the coordinator for El Pueblo Para el Aire y Agua Limpia/People for Clean Air and Water of Kettleman City. Maricela is a mother of two, and a long-time resident of the farmworker community of Kettleman City, California, home to the largest hazardous waste landfill in the western United States. She has been involved in the environmental justice movement. Maricela’s parents were founding Board members of Greenaction. Maricela graduated from Fresno State University in 2000.  She has worked as a teacher, employment counselor, and parenting instructor. Maricela serves on the steering committees of the California Environmental Justice Coalition, Central California Environmental Justice Network, and the Central Valley Air Quality Coalition. Maricela is on the Board of Directors for the Kettleman City Foundation. Maricela played a leading role in the fight against the expansion of Chemical Waste Management’s hazardous waste landfill, an effort that prevented the disposal of approximately 250,000 truckloads of toxic waste. Maricela was instrumental in the landmark settlement of the Title VI Civil Rights complaint filed by El Pueblo and Greenaction against the California Environmental Protection Agency and the state Department of Toxic Substances Control.  This historic settlement requires the state agencies for the first time to consider and comply with civil rights laws in their permit processes and permit and regulatory actions, including ensuring language access for non-English speaking residents and considering the cumulative impacts of pollution on vulnerable communities.

Ruben Rodriguez

My name is Ruben Rodriguez. I am the son of immigrant parents and a
proud Xicano. I have lived on the west side of Fresno County for the
majority of my life and have come to understand the need for immediate
social action. My experience working in the field and growing up in a
farm working community has allowed me to see the struggles and
injustices that these beautiful and resilient people face on a day-to-day basis. I stand with those that want to make this world a better
place! We must all do our part in society to assure that we resist this
nonsense and defend what is right! For our children, our elders, and all
of our relations!




Lori Thomas Riddle

Lori is the Director and co-founder of the Gila River Alliance for a Clean Environment (GRACE), a grassroots tribal member organization on the Gila River Indian Community reservation in Arizona working on environmental and sacred site and cultural protection. Lori was a leader in the fights that closed the Romic toxic waste plant and the Stericycle incinerator on the reservation. Lori and her family were poisoned by living on a site contaminated by pesticides.

Karen Susag, Board Treasurer

Karen rejoined Greenaction’s Board of Directors in January 2021.
Karen was a co-founder and original Board member of Greenaction when she worked with grassroots leaders from frontline urban, rural, and Indigenous communities to found our organization in late 1997.

A resident of the frontline community of Richmond, California, Karen has been a Greenaction supporter and community activist for many years. Karen says “My passion and desire for health and environmental justice are my grounding principles.”

As a cofounding Greenaction Board member, I remember the fundamental reasons for the founding of the organization. I remember the wind and the rain at Ward Valley during the occupation. I remember the sacred fire and the fundamental shift in my understanding and awareness of the stakes of environmental racism.

Karen believes it is essential for Native American tribes and frontline communities to lead the struggle for health and environmental justice, saying “Without this leadership, justice is not possible. This principle is the bedrock of Greenaction’s foundation.”

Karen worked at Greenpeace USA fundraising and working on a campaign in the early 1990s, both in Arizona and California. She then moved to the Bay Area where she focused on the link between cancer and environmental toxins and helped cofound the Toxic Links Coalition to help “Stop Cancer Where It Starts.”
