Founded by Gerard and Jesse Holodak, a husband-and-wife team of former public servants, our farm in Rainier, Oregon grows gourmet mushrooms and an organic-practice market garden with care and purpose. We are committed to healing our soil and our community by using regenerative farming practices to make functional food and natural medicine accessible to everyone. For us, farming isn’t just production—it’s path of purpose and continued service. We’re proud to cultivate something that strengthens our community from the ground up.

A promise to you is that every mushroom is thoughtfully and honestly grown—we carefully select our strains and substrates to ensure a pure product that still packs the medicinal power and flavor of the wild.  Choosing Koa Mushrooms means more than buying local produce. It means supporting sustainable farming practices that protect soil, water, and future harvests. Whether you’re a chef, a home cook, or someone simply looking for food that makes you feel good, we’re here to provide mushrooms that are organic, grown with care, and full of flavor.
