Meet The Team

Since 1982, ATSI has championed sustainability as Washington State environmental consultants, ensuring regulatory compliance and community balance.

We view sustainability externally—balancing social, environmental, and economic factors for human-planet harmony—and internally, by empowering our team, maintaining sustainable workspaces, and ensuring financial stability. As trusted arbitrators, we apply professional judgment to align development projects with regulations while fostering strong client, vendor, and regulator partnerships.

Committed to balancing human well-being with responsible resource use, ATSI creates a future where communities thrive, resources are preserved, and economic vitality endures. We win here when our decisions align with all three answers of our Hedgehog Concept questions.

Inspired by the principles from Good to Great, our Hedgehog Concept reflects the core intersection of what we’re passionate about, what we can be best in the world at, and what sustains our work. It’s the foundation for every decision we make and how we measure success over time.
