Why Choose Guidepost Montessori at Fort Mason

Children are born with a natural curiosity and love of learning. When nurtured and properly guided, this curiosity can unlock the door to deeper learning. Our team of educators at Guidepost Fort Mason is committed to honoring school in this way, treating each student as a unique, capable, and respected individual. We partner intentionally with parents and caregivers to foster an authentic love of learning as it naturally unfolds.

At Guidepost Montessori Fort Mason, we see firsthand the power of The Montessori Method. Through this child-led model that is deeply connected to real-world experience, children develop a strong sense of who they are, who they want to be, and how that fits into the world. They become self-motivated, responsible, caring, and creative contributors and leaders.

With our carefully prepared environments, we deliver a scientifically designed curriculum that further inspires children to create their own ideas, pursue their own interests, express their feelings, take risks, and make choices. Our educators guide your child through a world of discovery and responsibilities as they take greater strides towards meaningful independence.

Continuing Montessori Education for Middle School

Students can continue into middle school with the Academy of Thought and Industry (ATI) at Fort Mason.

ATI is Guidepost for the adolescent: a Montessori middle and high school network delivering a powerful education for independence, to develop curious, self-motivated adults who thrive in school and in life.

The ATI Middle School program operates at our Middle School campus, and is now enrolling for grades 6-8.

The future of school isn't about moving from one set of exams to the next. It's about becoming the person you want to be, and feeling fulfilled and supported along the way.
