Missy Rohs

Missy Rohs is a community herbalist and dandelion lover. She grows and wildcrafts her own herbs with a focus on sustainable herbal remedies: those that grow easily in populated habitats, and those that can be harvested in the wild with minimal impact.  

Missy’s path to herbal teaching began with grassroots labor activism and cross-border solidarity.  As part of her activism, she joined the Black Cross Health Collective, which provided integrative first aid and aftercare for activists, and used that as a springboard to dive head-first into the world of herbal learning.  Encouraged by her herbal mentors, Krista Olson and Colette Gardiner, she packed her bags to study with Michael Moore at the Southwest School of Botanical Medicine.  Upon her return to Portland, she began selling her tinctures at a farmers’ market and leading plant medicine workshops around town.

As the Arctos School has thrived, Missy has remained active in other parts of the herbal community, teaching at conferences, volunteering with Natural Doctors International in Nicaragua, and leading hikes for Bark.  In between herbal endeavors, she can be found concocting delicious meals with her sweetie, snuggling with her cats, or fighting for social and environmental justice.


Gradey Proctor

Gradey Proctor is a botanist and ecologist who has spent years studying the flora and fungi of Oregon's forests.  Growing up in a place without intact ecosystems, Gradey fell hopelessly in love with the Northwest upon his arrival in the '90s.  His longing to develop a sense of place has driven his passion for sustainably wildcrafting medicinal and edible plants -- and he loves supporting his community by teaching others to do the same.  

Gradey studied at the Columbine’s School with Howie Brounstein to hone his botanical skills.  Working with Bark, a nonprofit that advocates for and protects the Mt. Hood National Forest, added depth and breadth to his knowledge.  Gradey’s insatiable love of plants has driven him to work with both adults and children in nurseries, farms, and gardens.  His other herbal endeavor, the Medicine Garden, is an independent nursery specializing in healing herb starts.  Learn about upcoming Medicine Garden events, CSA herbal shares, and plant sales here.

When not hanging out with plants, Gradey reads about plants, advocates for plants, listens to an eclectic assortment of music, and spends lots of quality time with his daughters, Scarlet and Madrone. You can often find them rock hounding or camping together.
