Our Team


Alexis Barton, Coordinator
Cell: 530 (not 503) 902-7528

In managing Tryon Creek Watershed Council’s programs, Alexis enjoys wearing multiple hats on any given day, whether they be in coordinating restoration projects, implementing workshops, planning volunteer events, or facilitating coordination and collaboration across organizations.

Alexis’ first contact with Tryon Creek was within the Natural Area as a Camp Instructor with Friends of Tryon Creek for several summers. After finishing her B.S. in Environmental Studies, Alexis served for two years as a Confluence AmeriCorps member at Johnson Creek Watershed Council, where she gained experience in riparian restoration and volunteer management, including managing their Community Science program, leading environmental education, and the development of equity-driven planning processes. Alexis represents Willamette Basin Watershed Councils as a Region 3 Director on the Network of Oregon Watershed Councils.

Alexis seeks to consider and incorporate equity and justice lenses into all the work she is a part of.
She’s engaged with the North Clackamas Watersheds Council, Johnson Creek WC’s Community Inclusion Committee, City of Milwaukie Tree Board, and Friends of Elk Rock Island & Spring Park. Alexis spends time away from her desk with her partner and their dog and cats, experimenting both in the kitchen and on various crafts.
