Puget Sound Chapter

The Puget Sound Chapter of WIE was formally established in 2023 though we’ve been present and active here for years. We continue to facilitate opportunities to support women in the environmental field through mentoring with experienced professionals, networking across industries and skillsets, and professional development events covering a spectrum of topics.

We welcome people wishing to get more involved with WIE through one of our events or by jumping in to help us plan the next one or help us build our community across Puget Sound.
