Trees need People. People need Trees.

Working towards environmental and social justice among environmentally stressed communities.


Providing students, teachers and the school community with the knowledge, tools and support they need to create environmental change.


Restoring ecosystems, planting trees, and incorporating nature-based solutions from Los Angeles’ urban streets to mountain sides.
