Our leadership team is composed of local residents, experts, & advocates who are passionate about bold climate action in our Eastside communities. Check out the members of our steering committee below.

Lin Hagedorn

Climate activist/organizer. Worked as a Dental Hygienist since 1980 in a variety of practice settings and now recently retired.

I had the pleasure of Interning with 350 Seattle in 2013-14, and then was asked, by Alec Connon, along with five others, to launch 350 Eastside in September 2015. Through the mentorship of Alec, 350 Seattle, and the broader 350 networks we have provided a home for climate activists here on the Eastside. Much of our work on the Eastside also includes collaborating with other environmental and justice groups already well-established and supporting their work. Organizing has been a part of my volunteer life through my work with organizations like CWS (Church World Service), Meaningful Movies, and the UCC (United Church of Christ). It has been good to take that experience and apply it to systemic justice change work with a focus on the environment while also acknowledging the interconnectedness of all justice issues.
