Sandy and Julia Shettler are a mother-daughter team with Tree Action Seattle, which advocates for Seattle's trees at the neighborhood level and at City Hall.

Sandy is a medical social worker with a background in public health. She focuses on the physical and mental health benefits of living near trees, and the need to bring these benefits to deforested and underserved urban communities. Julia is an electrical engineer by training and works in climate tech. She is deeply interested in preserving the natural environment as a common-sense solution to climate change.

Tree Action Seattle is a collective effort that was sparked by the City of Seattle’s July 2023 approval of the cutting of a large western red cedar. Nicknamed “Luma”, the Snoqualmie Tribe identified the tree as historic and culturally modified. This singular tree illuminated glaring flaws in Seattle’s tree code.

Activists nicknamed “Droplet” sat in Luma’s branches and did not leave until the property owner chose to protect Luma. The community that coalesced around Luma’s protection catalyzed a movement focused on transparency, accountability, and sound urban forest policy.

Neelam Patil, M.Ed., MFA, is a Climate Literacy and Science Teacher in the Berkeley public school system. She was awarded TIME Innovative Teacher of the Year 2022 by TIME Magazine based on her work teaching children they can do something about climate change. Ms. Patil spearheaded the planting of the first Miyawaki schoolyard forests in North America in Berkeley, California. While teaching her students about deforestation, they wanted to do something immediate and impactful. They demanded, ‘Let’s plant trees!’, and the rest is history.

Ms. Patil has been an educator since 2000. Her work specializes in empowering children to face the most pressing challenges of our time through climate resilience, mindfulness, plant based culinary education, and youth urban forestry. She is a certified SKY Breath instructor and recently founded a non-profit, Green Pocket Forests, whose mission is to green urban spaces using the Miyawaki method.

Dave Muffly has been planting trees (especially oaks) in the Bay Area and other California locations for more than 30 years. Dave began his tree career when he received his undergraduate degree in mechanical engineering, at Stanford University. Moving from engineering to ecology, Dave managed native oak plantings at Stanford with the non-profit Magic, in a project that has yielded more than 4,000 established oaks in 40 years. Dave then branched into fruit trees, and urban tree plantings, with a special focus on street trees.

Dave subsequently became a Board Certified Master Arborist and designed/oversaw the 101 Freeway Soundwall planting as part of the East Palo Alto Tree Initiative led by the non-profit Canopy. This radical and experimental 1000-tree drought adaptation planting succeeded far beyond expectations and laid the foundation for the changes reverberating through the California tree nursery industry today. The East Palo Alto Tree Initiative became the proof of concept for the even more radically diverse plantings at Apple Park in Cupertino, where Dave spent seven years as Apple's Senior Arborist. Today Dave works as a senior arborist and horticultural futurist.

He worked as a field organizer on the Nuclear Weapons Freeze Campaign, and as a film distributor for The Video Project. For over forty years he has tended trees in the urban forest as co-owner of Brende and Lamb Tree and Shrub care.

In 1991, under the auspices of Earth Island Institute, Joe founded the Borneo Project, an NGO that helps the indigenous peoples of Borneo secure land rights and protect their forest. Honored by the Goldman Foundation as an “environmental hero,” Joe was featured in the San Francisco public television program, “Green Means.”

For over 30 years the Borneo Project has helped indigenous peoples map their lands, bring their case to the court of public opinion, and press for the preservation of their forests through legal action. Learn more about the Borneo Project – see the link below.

Joe is firmly committed to trees as an essential part of any realistic strategy to help the world limit and mitigate the potentially catastrophic consequences of climate change.
