Westword’s Best of Denver 2026 — Best Mushroom Company
This one means a lot to us because it came as a complete surprise — we did not pay to participate and were organically included by Westword, which is very cool and truly humbling. If you think we’re the Best Mushroom Company in Denver, we’d love your vote! You can vote once per day, so show our hardworking team some love. We pour our hearts into what we do, and this recognition is all because of this amazing community.
Thank you for the support — mush love always
