From the founder
Why Ross started writing about this
"I kept seeing people buy supplements they thought were mushrooms — and they were mostly grain. Nobody was explaining the difference in plain language. So I started writing it down. Everything on this page came from years of growing, harvesting, and watching the supplement industry cut corners. Read it before you buy anything — from us or from anyone else.

The Roots of Arbor Spring
Our Beginning in Michigan Soil
Founded in 2019 by Ross Devereaux and Dave Jones, Arbor Spring Farms began with a vision to bring premium, locally grown functional mushrooms to life—right in the heart of Michigan. What started as a passion project in a repurposed office building quickly grew into a mission-driven farm and production company that values traceability, freshness, and purity above all. But in 2024 we were blessed when Terence Barnes joined the team bringing a wealth of experience and knowledge as a long time grower of mushrooms.
From day one the team set out to know exactly where every element of the process came from. It all starts with our substrate—the nutrient-rich growing medium, typically a blend of hardwood sawdust and organic materials, that serves as the foundation for mushroom cultivation. This is where the mycelium, the root-like network of the mushroom, first takes hold and grows strong. Once inoculated, this substrate becomes what’s called spawn, the living, thriving system that ultimately produces the beautiful fruiting bodies you see on our farm.

Start to Finish
Completely Transparent Process
To protect quality at every level, we source our substrate exclusively from two trusted suppliers. From there, we maintain full control over each step of the journey—from cultivation to extraction—just miles from where our mushrooms are grown.
At Arbor Spring Farms, we’ve never used—and will never use—any chemicals or fertilizers during our growing process. Instead, we rely on carefully controlled environments and rigorous operating procedures to keep our mushrooms clean, potent, and naturally delicious. That’s how we uphold our promise of purity and deliver mushrooms you can truly trust.
Farm to Bottle
Fresh from Farm to Bottle
Every bottle that leaves our facility carries a born-on date and a batch-specific QR code, so you know exactly what you are getting and when it was grown. No shortcuts. No mycelium or grain. Just 100% fruiting body mushrooms, harvested and processed within hours to lock in freshness.
Today we offer Lion's Mane tinctures, powders, and mushroom coffee that support daily focus, clarity, and wellness — products we not only believe in, but use every day ourselves.
