Our Staff

Marti Townsend, Chapter Director


Marti became the Director for the Sierra Club of Hawaiʻi in June 2015 because she wants to build a movement to stop global warming.  Prior to taking on this role, she served as Executive Director of The Outdoor Circle, a 100-year-old advocate for public trees in Hawaiʻi.  While there she advocated for the law that established Hawaiʻi’s Environmental Court and helped secure quality appointments at the Department of Land and Natural Resources.  Prior to that post, she served as Program Director and interim Executive Director for KAHEA: The Hawaiian-Environmental Alliance, where she helped argue the case against construction of the Thirty Meter Telescope in the conservation district of Mauna Kea, establish the Papahānaumokuākea Marine National Monument (and Northwestern Hawaiian Islands State Refuge), and help a predominantly Native Hawaiian community on Oʻahu’s west coast combat environmental racism in their community.  She has also worked at Earthjustice and the Hawaiʻi State Capitol.  She is a graduate of University of Hawaiʻi’s William S. Richardson School of Law, Boston University, and Moanalua High School.

She is married with three kids.  As a result, she has the patience of a saint, a knack for fixing broken things, and extreme sleep deprivation.  Marti loves her job, but she can’t wait for the world to be saved so she can kick-off her dream career as a stand-up comic.

Jodi Malinoski, Chapter Policy Advocate


Jodi joins us as the Sierra Club of Hawai‘i’s Policy Advocate, after 2 years working as the Sierra Club Oʻahu Group Coordinator. She is excited to add her experience lobbying at the Legislature, coordinating grassroots campaigns for change, and planning successful events to the great work of Sierra Club’s staff and volunteers in Hawaiʻi.  A local girl born on Kauaʻi and raised on Oʻahu, she received her degree in Environmental Studies from the University of Hawaiʻi at Mānoa, where she focused on climate change and aquatic pollution.  Jodi was the Rise Above Plastics Coordinator for Surfrider Foundation, implementing their “Ocean Friendly Restaurant” campaign and advocating for legislation relating to water quality and plastic waste reduction.  She has also held environmental education positions at The Hawai‘i Nature Center and Kupu, where she was the Sustainability Fellow at Punahou School.  A pretty good karaoke singer and Netflix binge-watcher, she also enjoys traveling, hiking, and ice cream.

Kirsten Fujitani, Chapter Strategic Communications Manager


With a love for all things nature, Kirsten joined us from The Nature Conservancy of Hawaiʻi where she was part of the Marine Conservation Fellowship Program. At TNC she focused on communications and outreach initiatives centered around community-based fisheries management and climate change adaptation, and biological monitoring. With a Bachelor of Science in Marine Biology, Kirsten studied coral genetics, completed two Kupu Hawaiʻi Youth Conservation Corps programs, and interned at Paepae o Heʻeia. Kirsten has a passion for empowering people of their place to manage resources and take local action to increase resiliency in light of climate change. A diy-er at heart, Kirsten also teaches donation-based yoga classes and enjoys hiking and diving. She hopes to one day experience Papahānaumokuākea but must first overcome her death fear of birds.

Tanya Dreizin, Office Manager

Tanya joins us as our first office manager! She previously interned with us in Spring 2018 and brings 3 years of experience as an office manager, having worked for a local start-up company in Santa Barbara, California, learning new skills and helping in any capacity needed, and she is excited to bring those skills to the Sierra Club! Tanya is currently a graduate student at Hawaiʻi Pacific University, studying Global Leadership and Sustainable Development with a focus in sustainable tourism. She grew up in Dayton, Ohio, and has lived in Santa Barbara, California, and Seoul, South Korea, before moving to Hawaiʻi. Tanya was inspired to get involved with environmental causes because she loves hiking, rock climbing, and traveling, and wants to advocate for and protect the lands where we live and play.

Kecia Joy, Maui Group Manager








For over thirty years Kecia Joy has been a dedicated environmentalist, marine biologist, educator, and wellness practitioner with experience as team leader, director, and co-creator of innovative projects.

Lauren Watanabe, Oʻahu Group Program Manager








Originally from East L.A., Lauren is an artist and proud third generation working class Mexican-American. Her identity informs her passion for justice and she channels it into her work and art. After graduating from the University of Hawai‘i at Mānoa, she was a community/political organizer with UNITE HERE Local 5 and discovered her profound sense of purpose in connecting deeply rooted values to movement building. Throughout her time at Local 5, Lauren worked on several campaigns in alliance with diverse community leaders, students, and organizations, as well as created art based protests for actions and rallies.

During some time in L.A., Lauren spent time at a Chicanx women’s theater collective, whose objective was to organize theater festivals that celebrated the unique voices of women and provided critical spaces to speak their truths. Since moving back to Hawai‘i in 2019, Lauren became a member of Hawai‘i Playbuilders – a local, community-based theatre company that shares real stories throughout the culturally rich and diverse communities of Hawai‘i. She is beyond thrilled to join the Sierra Club of Hawai‘i team in the fight for climate justice—to grow a broad-based movement that centers our community in an understanding that everyone’s issues are interconnected. 

Lauren is also a bike commuter that dreams of an eco-socialist future full of vegan foodies with “Fab 5” realness.
