Our School

My daughter Claire just recently woke up one morning with a big smile on her face and I said, “What are you so happy about?” and she said, “I get to go to school today!”  – Sunstone Parent

Our Mission, Vision & Commitment to Diversity

As a parent, I believe our role is to raise confident, independent and inquisitive children. My experience is that Sunstone Montessori School puts this into practice every day.  – Sunstone Parent

About Our School

We are a community of intellectually curious, independent, and compassionate lifelong learners. As a community, it is our mission to develop the whole child by providing an academically strong, emotionally nurturing and, socially supportive environment in accordance with AMI guidelines for Montessori education.

At Sunstone we nurture the child’s natural curiosity and empower them to make their own discoveries which leads to a lifelong love of learning. We cultivate the higher-cognitive brain functions critical for advanced problem solving, which leads to intelligent, critical, and creative thinkers who can think outside the box. We actively develop and refine the social skills necessary for confident, compassionate, and responsible human beings.

At Sunstone Montessori we provide rich interactive environments, scientifically designed to meet the developmental needs of children ages 16 months through 6th grade.  In these supportive learning environments, indoors and out, children thrive as they develop the academic, social, physical, and emotional skills to succeed in life.

Sunstone Montessori School welcomes students and staff of any race, disability, veteran status, sexual orientation, gender identity, color, nationality and ethnicity, religion, and family constellation to all programs and activities at the school. The school does not discriminate in its educational, hiring, admission, or school-administered policies. It is our goal that Sunstone Montessori School reflects the rich diversity of our community, including varied cultures, economic status, and individual or special educational needs.

Our Programs

Our History

Looking back, we can comfortably say that choosing Montessori education for our kids is our best investment, and sending them to Sunstone Montessori is one of our best decisions made.  Sunstone Parent

Sunstone Montessori School has a rich history of growth, evolution and collaboration with the vibrant Montessori community of Portland, Oregon.  The successful merger in 2007 of two well-established Montessori schools, Odyssey Montessori School (ages 6-12 years) and Two Rivers Montessori School (ages 2 ½ to 12 years) created what is now Sunstone Montessori School.

An extensive, three-year search produced a location where we could combine both schools onto one campus. Sunstone signed a lease with Portland Public Schools in May 2012 for the former Terwilliger School site located on Corbett Avenue. Renovation occurred over the summer of 2012 and the 2012-13 school year began with all Sunstone Montessori children in one location. In the fall of 2013 we launched our first Toddler classroom with children ages 16-36 months.

We will be moving all of our programs at the end of this school year to a new location in SE Portland. Renovations at our new site will occur this year in time for our doors to open in the fall of 2021.

Sustainability at Sunstone

At Sunstone Montessori School, stewardship for the earth is central to our everyday life. Being environmentally conscious is the culture of our community, in our classroom conversations, our daily lessons, the materials we use, the products we consume, our relationship with others and our place on the planet.

We have been awarded several professional certifications that we work diligently to maintain and uphold, including Premier status with Oregon Green Schools and City of Portland Sustainability@Work (Gold Level 2014). These certifications were achieved with the support of dedicated parents, students and staff. We also participate in the Portland Eco-School Network and are a member of the National Wildlife Federation Eco-School USA program. We are passionate about maintaining our sustainable practices as well as discovering new ways to be agents of change and environmental stewards for our communities.
