Columbia Land Trust strives to employ great people. Our scientists, stewardship staff, conservation practitioners, and development team are among the best in their fields. More important, they are connected to their communities and deeply invested in the future of the Northwest. Our staff is committed to working with integrity and listening to many points of view, even those that differ from our own. We believe that it’s only by coming together, by finding common ground with the wonderfully diverse people who live and work in our region, that we all can create a Northwest that will endure.
