2018 Chapter Executive Committee
Meet our ExCom Members:
Colin Yost is an environmental advocate whose career includes roles as a Green Corps Organizer in Philadelphia, an attorney representing Sierra Club of Hawaiʻi on the pivotal Koa Ridge case where development threatened productive agricultural land, as well as other land use, public access and marine protection matters affecting our island state. Notably, he was also the Civil Fraud prosecutor against Enron and recovered $32 million dollars for Oregon consumers. Currently, he’s a part-owner and Chief Operating Officer of local solar energy and smart home company, RevoluSun.
Lucienne de Naie is a long time Club member who has served as Chair and Vice-chair of the Sierra Club Hawai‘i Chapter Executive Committee. She is a researcher and writer whose passion is protection of native plants, streams, watersheds, and cultural sites.
Nara Takakawa, Treasurer
Kim Toomey is an active community volunteer and avid hiker who owned and managed a successful multi-million dollar business before moving to Maui six years ago. She also has experience as a director of project management. Kim looks forward to using her professional skills to serve the Hawaii chapter and help protect these unique and beautiful islands.
Serving on the Kauaʻi Group ExCom since 2004 and as Kauaʻi Group rep for the Hawaiʻi Chapter from 2008-2013, Rayne works diligently to preserve the island’s unique environmental resources and rural character. She is a dedicated advocate for historic trail access and currently serves on the state Na Ala Hele Kauaʻi Advisory Council. She is active in community issues related to land use and sustainability, and is passionate about preserving the island’s cultural heritage and monitoring shoreline applications to protect coastlines from encroaching development.
Randy has been a volunteer for 25 years and has held almost every position in the Club. His work with the Club has focused on climate change adaptation, water protection, and engaging more members in service projects and outings. Currently, he is working on increasing DLNR funding for the maintenance of trails, beaches, and state parks—and strongly believes more funding should go to DLNR than to the Hawaiʻi Tourism Authority. Together with Dave Raney he is also working with lawmakers on sea level rise adaptation policies.
Sheila Sarhangi is a communications strategist who specializes in partnering with communities, nonprofits, foundations, and government agencies to achieve conservation goals. She has worked on a wide range of environmental issues across the Pacific, in Hawai‘i, Palau, Fiji, Papua New Guinea, the Northern Mariana Islands and Indonesia, on issues ranging from endangered species protection to community-based fishing rules and public access. She was also the local campaign director for the expansions of Papahānaumokuākea and the Pacific Remote Islands Marine National Monuments.
As an associate attorney at Earthjustice, Kylie has represented grassroots community groups, including the Sierra Club and has been advocating for clean energy, restoring stream flows, cleaner ocean waters, and better pesticide regulation. Kylie has interned for the Hawai‘i Public Utilities Commission, Blue Planet Foundation, and worked as a research associate for the Center for Island Climate Adaptation and Policy. She has served as a law clerk for the Honorable Mark E. Recktenwald and an extern for the Honorable Richard R. Clifton. Kylie is a proud graduate of the UH’s William S. Richardson School of Law, with a certificate in environmental law. Her experience reporting on environmental and cultural issues on Maui inspired her to become a public interest environmental lawyer in Hawai‘i.
Nate Yuen works as an accountant for an engineering consulting firm during the week but on the weekends he becomes an amateur naturalist, hiker, and photographer focused on the flora and fauna of Hawaiʻi. His blog – HawaiianForest.Com – documents some of the rarest species on the planet. In 2013, he was appointed to be a commissioner on the Natural Area Reserves System Commission which oversees the most biologically and geologically sensitive lands owned by the State of Hawaiʻi. Through his involvement in conservation he has become an advocate and activist for creating critical habitat for native species, keeping our sources of fresh water clean, ensuring stream water rights for kalo farming, and a host of other environmental, climate change, food sustainability and political/economic issues crucial to creating a sustainable future for our islands.
