At Cascadia Mushrooms, we provide the finest gourmet and medicinal mushrooms available. All of our products are certified organic, and we believe we can do even better than what many organic regulations call for.

We follow our own rigorous standards above and beyond the certification. Every input we use to produce our products, from grain to spawn to sawdust, comes from certified organic or verified naturally-sourced and non-treated sources. We avoid buying any supplies or products that were grown using pesticides or GMOs.

our mission

quality, community, awareness

From those early days to today, the vision has stayed the same: produce the best quality mushroom products possible and feed our community while raising awareness of our humble fungi friends.

Fungi have the innate ability to cleanse the soil and heal the environment. Our farm exists to nurture that ability, while feeding our community good, healthy food. Along the way, we hope to spark the curiosity and wonder that the world of mushrooms incites.

Thanks for supporting our small family farm!
