Current Families


We are a community committed to developing self-assured, lifelong learners who are compassionate, globally minded, and empowered to positively impact the world.

We offer a unique Montessori education that promotes curiosity, inquiry, and engagement for children ages 3 through twelfth grade. STEM and environmental education are integrated and interdisciplinary learning experiences foster independence, self-assurance, collaboration, and connections to the global community.

Along with a deep, rich, academic curriculum, we value collaboration, effective conflict resolution, cultural awareness, and teaching respect for each other and the environment. We use community as an extension of our indoor classrooms for learning, exploration, community service, and play.

We invite you to become active participants in our learning community and applaud your commitment to your child’s education.

“Thank you [teachers] for letting us know you too are finding growth. It’s reassuring to discover my child is proving he is blossoming into a strong, self-reliant individual. While, I am sure you and the rest of the Montessori staff don’t hear this often but, all of you are just as responsible for the individual my child is becoming as me and his mother. It has taken all of us, pushing and caring about him that has made him who he is, and I thank you all for that.

Teachers update scores for daily work, assignments, and tests on JMC frequently so parents can have positive conversations with their children about their work and stay abreast progress and grades.

Stay on top of what’s happening at school. No matter where you are or what you’re doing, get important classroom updates right on your phone.

Extraordinary things happen at school every day. Don’t miss out on them. Montessori Compass (online or app) keeps you informed about your child’s academic progress, social development, and all those wonderful moments of childhood spontaneity that make LMSS an enjoyable place.

Study Island is an online learning opportunity built from Minnesota standards. By working on Study Island, students strengthen math, language, and science skills and gain practical life experience with the same types of items they will see on state assessments.
