WHY PARENTS CHOOSE SIMS

More than a preschool.

A foundation for life.

Spanish Immersion Montessori School was built on a simple belief: the early years shape how children see themselves, how they learn, and how they connect with the world.

At SIMS, we help children build the skills that matter most for life.

IN SPANISH.

Across our Newton and West Roxbury campuses, every child is known by name and welcomed like family.

Full Spanish Immersion

Native Spanish-speaking guides lead every activity in Spanish. Children absorb it effortlessly during the most receptive years of their lives.

Authentic Montessori

A prepared environment where children choose their own work, set their own pace, and build genuine independence.

Music & Movement

Our ABC Spanish in Motion curriculum weaves Latin American music, movement, and cultural exploration into every school day because language lands best through the body.

Guides, Not Teachers

Our educators are trained Montessori guides - observers and facilitators who know when to step in, when to step back, and how to honor each child's individual rhythm.

The Sensitive Period for Language Acquisition

The window for effortless language acquisition is open. but it won’t stay open forever.

Children at SIMS don't study Spanish. It becomes part of who they are — the way any native language does.

Founder's note

Why I created SIMS.

SIMS began with a simple dream for my own daughters: to grow up bilingual, confident, and excited about learning. That dream became a school where children are nurtured, respected, and encouraged to thrive through authentic Montessori education and full Spanish immersion. I'd love to welcome your family and show you what makes SIMS so special.
