Rooted in Arusha, growing for Tanzania.
We are a young, registered NGO founded in 2025 by a doctor who believes healthy people need healthy land.
Our story
From the clinic to the forest.
Five years as a doctor showed our founder how closely people's health depends on the land around them: clean water, fertile soil, shade and fresh air.
In 2025 that conviction became Our Trees, Our Life, known in Swahili as Miti Yetu, Maisha Yetu. We are a registered NGO in Arusha that plants trees with schools and communities and teaches the next generation to care for them.
Our name says it all: when our trees thrive, our lives thrive too.
Our vision
A greener, healthier Tanzania where trees, people and wildlife thrive together in harmony.
Our mission
To restore forests, conserve biodiversity and empower communities through tree planting, climate education and sustainable livelihoods.
Meet the founder
I worked as a doctor for five years. In 2025, I proudly turned my vision into reality by launching Our Trees, Our Life.
Today Lisiantosi leads a growing team of staff and volunteers who bring planting days, climate lessons and seedlings to schools and villages around Arusha.
What guides us
Five values, planted deep.
Sustainability
We plant for the long term, choosing species and care plans that last for generations.
Environmental Stewardship
We protect soil, water and biodiversity as a shared inheritance.
Community Engagement
Every project is planned and planted with local people, not for them.
Education & Awareness
We help students and families understand climate change and act on it.
Transparency & Accountability
We report openly on every tree, every shilling and every partnership.
How we work
From seedling to shade, step by step.
Listen
We meet schools, village leaders and local authorities to choose the right sites and species together.
Plant
Students, families and volunteers plant seedlings side by side on community planting days.
Care
Young trees are watered and protected through their first dry season, the moment they need it most.
Measure
We track survival, share results openly and use what we learn to plant better next time.
