Joyce Devlin Mosher, PhD
I have been a member of Sierra Club for thirty-five years, and active in the local Sierra Club Group, the Headwaters Group, for several years. I have served two terms on the Executive Committee and am now seeking another two-year term.
My strengths on the Executive Committee include organizational skills—planning county-wide events that partner with other Colorado environmental, social, and political groups, and preparing monthly meeting Minutes with the Chair. As delegate to the state, I attend monthly meetings of the Colorado Steering Committee. I enjoy Sierra Club outings and volunteering during the many Headwaters activities throughout the year.
A resident of Breckenridge for fifty years, I have been involved for many decades in conservation and river restoration projects, as well as Forest Service initiatives such as Travel Management Plans and other Summit County wilderness efforts.
I am Professor Emerita of Colorado Mountain College, where I taught for fifty years, supporting and advising young people in curriculum and career paths in the Bachelor of Science in Ecosystem Science and Stewardship and the Bachelor of Arts in Sustainability Studies Degrees. I continue to be active at the college and in public education in various Summit County arts and environmental organizations.
I believe it is more important than ever to ensure that Sierra Club survives as the premier grass-roots environmental group in the nation, and I desire to put my time and effort toward protecting biodiversity and community activism.

I serve as the Workforce and Wild Horse Policy Advisor at Rewilding America Now (RAN). My work is guided by a simple truth: wild horses should be that, not managed toward extinction by our government, ranching interests and extractive industries. For the past decade, I’ve worked alongside Jared Polis and other advocacy groups on wild horse issues, and served on Colorado’s SB 23-275 Wild Horse Workgroup, to help shape a more humane and sustainable path forward.
My passion lies in protecting wild horses as part of a larger vision because their future can only be secured within healthy, diverse environments. Rewilding gives us one of the most promising ways to achieve this balance, restoring not just ecosystems, but the deeper relationship between people, wildlife, and the land.
I joined the Headwaters Group because of its progressive vision and its belief in the power of alliances. Together, I believe we can shift the trajectory of our individual causes, creating the momentum needed for real innovation and systemic change here in Colorado.
I’ve always believed that fighting for the environment means moving as one with every wild animal cause supporting the others, just as nature herself weaves strength through unity when we allow her. That belief is what fuels my work and my life.
My two rescued Standardbreds and two mustangs remind me every day why this work matters. They are my teachers, grounding me in the urgency of protecting wild horses and inspiring me to keep pushing for a future where all species have room to thrive.

My membership and involvement in the Sierra Club spans 50 years, starting in San Francisco, California and continuing in Summit County, Colorado.
I have participated in and led outings, supported local, state and national environmental legislation, and provided financial support for general and specific Sierra Club issues.
When we moved to Summit County, I joined the Headwaters Group of the Colorado Chapter and have served as the Membership Chair, Outings Chair, and Conservation Chair. I took the LACE training in 2019, and have actively participated in reviewing environmental legislation, contacted legislators on Club-identified issues, and lobbied for Club-supported political candidates.
I am a member of the Summit County Democrats and have served as a Precinct Committee Person. I also rallied members and the general public to collect signatures on behalf of the Colorado Gray Wolf Reintroduction Initiative (2020).
Being associated with the right side of politics is a win-win for me. We need to know our way in this political environment in order to protect the wilderness, wildlife, water and climate that we treasure.
I am running for the Headwaters Executive Committee because I believe in the many causes that our members are engaged in, from lobbying for more wilderness and protection of our public lands, restoring gray wolves to their ancestral range, and pushing for climate action.
We are a vibrant and engaged Group. I consider the active members as cherished friends and I want to continue our success by contributing as a member of the Executive Committee.

I live in Silverthorne. I joined the Sierra Club in 1984. I was a professor and research scientist at Mercer University School of Medicine in Georgia for most of my professional life. In the absence of a local Sierra Club group there, I joined The Georgia Wilderness Society, serving as a member and eventually President.
I have been an active member of the Headwaters Group for almost 20 yrs. I have organized and/or participated in activities such as promotion of pollinators, invasive weed control, restoration of mining damaged areas, highway cleanup, celebration of Earthday, etc.
Because the population of the area served by the HWG is relatively small, I believe it is crucial that we collaborate with other environmental groups to maximize our effectiveness. Accordingly, I also participate with other local organizations such as Friends of the Dillon Ranger District, Forest Health Task Force, etc.
