Secretary: Dav Yuan
Dav has dedicated his career to understanding how knowledge can be effectively shared across ages and communities. Since 2014, he has led The Digital Bus, a mobile science and culture education program now part of the Maui Economic Development Board, providing free, experiential learning opportunities to underrepresented students across Maui Nui.
Trained as a biologist with a focus on animal behavior, Dav holds an undergraduate degree from St. Mary’s College of Maryland and a master’s degree from Clemson University. Over time, his passion shifted from collecting information to sharing it, leading him from outdoor guiding into education and eventually into program leadership. Outside of work, Dav enjoys photography, cooking, exploring new places, and spending time outdoors with his wife and young son.
Treasurer: Brad Eichhorst M.D.
Brad Eichhorst, M.D., is a Minnesota native who majored in biochemistry at the University of Minnesota and spent the first part of his professional life studying placental permeability before electing to pursue a career in medicine. After completing his medical training at Mayo Clinic College of Medicine & Science, Brad joined the staff of Mayo Clinic. He served as Chairman of the Department of Family Medicine at Mayo Clinic Scottsdale and directed the implementation of one of the first paperless electronic record systems at Mayo Thunderbird Family Medicine Center in Scottsdale, Arizona. In 1996, Brad left clinical practice to join Epic Systems Corporation in Madison, Wisconsin, and spent the next 16 years promoting the development and use of computerized health records. He was named Vice President for Clinical Informatics in 2001 and retired from Epic in 2012.

Director: Erin Johnson
Erin has over ten years of experience working with conservation groups and nonprofits across South America, New Zealand and Hawai'i. She holds a Master of Conservation Biology from Victoria University of Wellington, New Zealand and graduated from the University of Montana with a B.A. in Biology. Her first job was with a conservation start-up non-profit, which led her to pursue innovative conservation biology practices in New Zealand. She began pursuing conservation in Hawai'i in 2016 with the Maui Forest Bird Recovery Project and the Maui Nui Seabird Recovery Project. In 2019, she assisted with the translocation of the kiwikiu to Nakula Natural Area Reserve and efforts to track and monitor the home ranges of wild birds in the Hanawi Natural Area Reserve. Over the past five years, she has been involved with supporting operations for the Maui Invasive Species Committee and the Maui Forest Bird Recovery Project.
Founder and Advisory Board Member: Hanna Mounce, PhD
Dr. Hanna Mounce is the Program Manager of the Maui Forest Bird Recovery Project (MFBRP), where she leads efforts to protect and restore Hawaiʻi’s endangered native birds. With nearly 20 years of experience in island conservation, her work focuses on habitat restoration, applied research, and innovative strategies to address threats like avian malaria. Under her leadership, MFBRP led the first successful reintroduction of ʻalalā (Hawaiian crow) to Maui in 2024—marking the species’ historic return after over a century of absence. She also oversees implementation of the Incompatible Insect Technique (IIT), a mosquito control method aimed at halting the spread of avian disease. Originally from the mainland U.S., Dr. Mounce developed a passion for island ecosystems and ornithology during her undergraduate studies and later earned her Ph.D. in wildlife biology. A respected voice in Hawaiʻi’s conservation community, she collaborates widely with researchers, agencies, and local communities. A 2013 Ka Ipu Kukui Fellow, she strives to live sustainably on Maui and is the proud mother of two.
