Today we honor Juneteenth, a celebration of freedom, resilience, and the ongoing pursuit of justice.

In the Montessori environment, we strive to nurture respect, dignity, and a deep appreciation for the diverse stories that shape our communities. As we reflect on this important day, we recognize the value of understanding history and fostering a more peaceful and equitable world for all.

We are deeply moved when families share their experience of our community and the children’s journey:

“We couldn’t be more grateful for the exceptional dedication shown to our child this year—hard to believe he’s been in their class only nine months. The quality of instruction is clearly outstanding: he has learned and grown in ways that nurture both his intellect and his character. The Montessori pedagogy truly resonates with him, and we feel fortunate to see it in action each day. Communication with the guides is consistently prompt and thoughtful, and every staff member we meet is warm, friendly, and genuinely interested in knowing our family. And we love First Fridays—they build community and give us a window into our child’s learning.”

Moments like these reflect the heart of our work—honoring each child’s development while building a strong, connected school community. 💛

Summer is here, and the learning never stops at MLS! ☀️🌿

As the seasons change, our classrooms and outdoor spaces continue to inspire curiosity, creativity, and independence all year long. We love watching our students thrive in an environment where learning follows their natural curiosity — even in the sunshine-filled days of summer.

families, guides, and community members who made this year so meaningful. ✨

Thank you to everyone who joined us for our End of the Year Celebration and for being part of a community rooted in curiosity, growth, kindness, and connection. Watching each child grow into themselves has been such a gift.
While we say “see you later” to some friends for the summer, we’re excited to continue the journey with those joining us for Summer Program beginning June 1st. ☀️

Wishing all of our families a peaceful, joy-filled start to summer. 💛

For families seeking an alternative to testing-driven schools 🌿

Many children come to us after losing confidence in traditional elementary classrooms feeling overwhelmed, unchallenged, or disconnected from learning. In our Montessori Elementary community, children ages 6–12 are given the space to rebuild focus, independence, and a genuine love of learning through hands-on exploration and individualized instruction.

With mixed-age classrooms, uninterrupted work periods, and meaningful academic experiences, children are supported not only academically, but emotionally and socially too. A calmer, more intentional approach to elementary education where confidence can grow again. ✨

Our Elementary community stepped into meaningful work at PHI GLOBAL FARMS 🌱

A space rooted in community, where education, sustainability, and access to healthy food come together to uplift and empower. Children experienced what it means to care for the earth while caring for one another.

We are so grateful to Mitch and Joyce for welcoming our class and sharing this work with us.
