On May 18, 1980, the eruption of Mount St. Helens changed the Pacific Northwest forever. The disaster caused widespread destruction and impacted thousands of families and communities across the region.
In the aftermath, Grange Insurance Association helped policyholders recover by paying 386 volcano-related claims. More than four decades later, we remain committed to helping protect what matters most when the unexpected happens.

For more than 130 years, we’ve been proud to serve families, farms, and communities across the West. Now, we’re taking the next step. Grange Insurance Association is becoming Granwest Insurance, effective July 1, 2026.
While our name is changing, the things that matter most are staying the same. You’ll continue to have the same coverage, the same support, and the same trusted relationship with your independent agent. No action is needed—just a new name that reflects our future.
We’re proud to continue protecting what matters most to you. Visit our website for additional information: https://heyor.ca/Nx80ul
