YAUHTLI BREÑA MILLÁN | they/them
Education Assistant

Yauhtli/ Isa (they/them) is an earth steward on occupied Ohlone land. Born and raised in Yelamu (SF), Yauhtli began stewarding in 2017 at Hummingbird Farm with a focused interest in plant medicine. Brought to plant medicine at a young age through experiences of inner-city violence and trauma, Yauhtli turned to it as a path for personal and community healing. Their experience comes from passed-down ancestral knowledge and cultivation of a relationship with the land and relatives. Plant medicine is often the first form of medicine for communities of color and communities with migration stories. For this reason, it’s important to them to share access and knowledge. Now, Yauhtli continues to provide access to plant medicine through local initiatives like the Freedom Community Clinic in Oakland, Apothecary For The People, and collaborative projects throughout the Bay Area. Yauhtli continues to support stewardship at other local sites throughout the Bay Area. They completed the GFE Get Up! program in 2023, Agroecology Farmer-to-Farmer program in 2024, and is Certified in Permaculture Design.
