Board of Directors

Interim President
Anna grew up in The Netherlands, where much of the country is below sea level and the highest elevation is just over 1,000 feet. Perhaps that sparked her fascination with the outdoors in general and mountains in particular. Anna was a TRTA-led thru-hike participant in 2016 and by the next summer, became a thru-hike guide for the TRTA. She has traveled extensively- to Nepal, Tanzania, New Zealand, Iceland, the North Pole! among others- for varied outdoor adventure experiences, but the Tahoe Rim Trail remains her favorite playground.
Professionally, Anna holds a BS in Electrical Engineering & Computer Science from UC Berkeley, and after working in the tech sector for a decade, transitioned to immigration law. In that field, Anna served as legal representative to hundreds of asylum seekers and immigrant victims of domestic violence. She founded and served as founding CEO of a non-profit organization that specialized in immigration services for LGBTQ+ immigrants. Now retired from immigration, Anna has co-founded Alcohol Exposed, a non-profit organization that provides education, guidance and resources to achieve health, wellness and quality of life by reducing or eliminating alcohol, making her the most unpopular person at social gatherings. Anna hopes to bring her experience in non-profit management and fundraising to the TRTA.
Anna maintains strong ties to her family in both Holland and Sweden. She’s a polyglot, musician, California Naturalist, Wilderness First Responder, and Mental Health First Aider. In addition to the TRTA board, Anna sits on the board of the US Alcohol Policy Alliance and is on the Advisory Board for Oakland Goes Outdoors, which provides outdoor experiences for students in the Oakland, CA public school district.

She has backpacked the entire Tahoe Rim Trail three times: first as a TRTA program participant, then as a guide with the TRTA, and once solo. She has also completed the High Sierra Trail, Nepal’s Annapurna Circuit, and cycling trips across multiple continents.
Professionally, Dori is a Technical Program Manager at Google with more than 15 years of experience in strategic planning and project management. In addition, she is a passionate fundraiser, supporting events like AIDS/LifeCycle and the TRTA’s Raise the Rim. She is excited to bring her skills and love for the trail to the board. When not working or on the trail, Dori enjoys reading, cooking, and spending time with her mini-Dachshund, BrakePad.
