Rooted in Tanzania, growing for East Africa.

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.

That conviction grew into Our Trees, Our Life, known in Swahili as Miti Yetu, Maisha Yetu. Today we are a registered NGO with an experienced team, planting trees with schools and communities and teaching 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

Years in medicine taught me that healthy people need healthy land. Our Trees, Our Life is how I turned that vision into reality.

Today Lisiantosi leads an experienced team of staff and volunteers who bring planting days, climate lessons and seedlings to schools and villages across northern Tanzania.

What guides us

Five values, planted deep.

01

Sustainability

We plant for the long term, choosing species and care plans that last for generations.

02

Environmental Stewardship

We protect soil, water and biodiversity as a shared inheritance.

03

Community Engagement

Every project is planned and planted with local people, not for them.

04

Education & Awareness

We help students and families understand climate change and act on it.

05

Transparency & Accountability

We report openly on every tree, every shilling and every partnership.

Where we work

Tanzania today. East Africa tomorrow.

For now our focus is Tanzania, and we are expanding one community at a time. Each new area builds on the experience of the last.

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.

Plant today. Breathe tomorrow.
