For over 90 years Ostrom Mushroom Farms has been deeply rooted in the rainy, mushroom–friendly climate of the Pacific Northwest. We have grown into the largest producer of fresh agaricus mushrooms in the region and have a long history as the Pacific Northwest’s favorite mushroom.

With our new state-of-the-art farm in Sunnyside, Washington, Ostrom renews its dedication to serving and meeting our customer’s desire for the freshest mushrooms.
