What inspires you to do this work?

I'm inspired by the dedication to clean water and thriving communities, and a sense of responsibility to be a good steward of the earth. Being part of that work also gives me hope for the future and a stronger sense of connectedness to our region.



Riverkeeper’s team includes scientists, environmental lawyers, and community organizers. We work to organize and empower local communities, enforce environmental laws, and build strategic coalitions. Our mission is to protect and restore the Columbia River and all life connected to it.
