Who We Are

Olive Children Foundation is a 501c(3) nonprofit, educational organization that strives to prepare our children to be the future leaders of tomorrow. Our first site (Olive Mission) opened in the heart of Mission Boulevard across the street from the olive trees of Ohlone College, Fremont, California. Today, we have three sites in Fremont (Olive Children Mission, Olive  Children Warm Springs, and Olive Children St James). Founded in 2010 by an educator and entrepreneur- Joni Jen- it embodies the ideal that young children can make a significant impact by serving their community. As a visionary entrepreneurial duo, Joni and her team strive to uncover students’ leadership and academic potential while improving their self-esteem and core strengths. Together, we believe leadership blossoms in every child.

What We Do: Youth Leadership

In tandem with Fremont Unified School District’s 8 Great Traits and Tribes Learning Communities philosophy, students will learn leadership through community-building activities. Each month, we focus on one or more traits. How can we incorporate these traits into our speech, attitude, and behavior towards others? After exploring the trait through discussion and tribal interactions, the month culminates in a collaborative service project.  Each project requires students to problem-solve, find resources, and interface with diverse populations. Our understanding of community itself will expand from our classroom or campus into our collective, neighborhood, and city.

At Olive: Friday Community Meetings

Students engage in a Community Meeting where they can share their feelings and make good decision about their learning environments.

Students can propose new ideas such as a “Silence-No Talking Homework Room” or address an existing issue such as what to do with Student Store Profits.

The meeting concludes by giving space for students to Acknowledge their peers to encourage reflective and positive thinking.

“Not all of us can do great things. But we can do small things with

great love.”

― Mother Teresa

In Our Community: Serving Others

Even the youngest generation can make a difference in their community as demonstrated by students at Olive WS and Berkeley Academy.

Seventeen eager students arrived at the ABODE Sunrise Village Shelter with a common goal in sight- serving others.

After serving over 30+ family members, students followed proper etiquette and cleaned up after themselves.

We provide the financial scholarships to under-served students to attend the summer camps and afterschool activities.

Around the World

Homebuilding in Mexico

Since 2014, We’ve worked together with many families and conducted numerous presentations to the communities. As of Winter 2015, 30+ homes have been built by our Bay Area families and high school students from Mission San Jose High, James Logan High, American High, Irvington High, Cupertino High, as well as Pleasanton and San Ramon High Schools. More than 250 people have been involved in homebuilding. 

Adopting Children 

Olive Children Foundation has been sponsoring children around the world through World Vision for the past 4 years. We want to address global inequality by giving struggling families a chance at an education. Currently, we sponsor 30+ children all over the world.

Rummage Sale for Nepal

After the devastating earthquakes in Nepal, our students wanted to help! We focused all of energy on Leadership Fridays: Rummage Sale to Benefit Nepal.

Students created art pieces, made posters, advertised, and wrote articles in the local paper to gather attention. Students asked local businesses for donations and went through their homes to donate their items.

We had an awesome and very successful rummage sale and bake sale!

American Youth Ambassador

Join us in the summer of 2018 as we sent out over a dozen students to China for a cultural learning experience. Students had been trained over a series of weeks to in preparation to teach English in China. Through excursions and tours, students came back with an appreciation of Chinese language and culture.
