ERSM was founded by a group of friends who shared a common vision: to build a company centered on environmental stewardship, conservation, and putting people first.
As lifelong outdoor enthusiasts, we've spent countless hours exploring Oregon and Washington's rivers, streams, forests, wetlands, and mountains. Those experiences shaped who we are and inspired us to create a company dedicated to protecting the natural resources we all enjoy. Clean water, healthy ecosystems, and responsible land management aren't just part of our work—they're part of who we are.
From the very beginning, we knew we wanted ERSM to be different.
In an industry where large corporations often prioritize profits over people, we believe that every employee is just as important as the people leading the company. Our success is built by the entire team, not just those at the top. We believe in creating a workplace where hard work is recognized, ideas are valued, and everyone has the opportunity to grow together.
Why work somewhere else when we can build something meaningful with our best friends, trusted colleagues, and a team that shares the same values?
Every day, we have the opportunity to make a difference. Whether we're restoring a stream, protecting a wetland, preparing environmental permits that help minimize environmental impacts before construction begins, improving stormwater systems, stabilizing a construction site, or helping clients stay environmentally compliant, our work contributes to healthier communities and a stronger future for generations to come.
We believe environmental responsibility and exceptional service go hand in hand. By combining technical expertise with a genuine passion for conservation, we help our clients navigate permitting requirements, minimize environmental impacts, complete projects responsibly, and protect the natural resources that make the Pacific Northwest unique.
At ERSM, our mission is simple:
Take care of the planet, and take care of your people.
That's why we're here.
One stream.
One river.
One wetland.
One project at a time.
