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. We are excited about growing our company to meet the ‘mushrooming’ demand! Like seafood, coffee, and apples, mushrooms are the perfect kitchen staple for a modern Pacific Northwest culinary lifestyle; delicious, nutritious, and sustainably-grown.
Our mushrooms are picked, packed and delivered fresh daily to our customers in Washington, Oregon, Alaska and Hawaii. Our team of over 200 employees is dedicated to providing the best and safest product in the industry. As we move into the next 90 years exceptional quality and service will continue to be our focus and our passion.
