Montessori Elementary School near San Bruno
The reason most families end up at Mills rather than somewhere closer: almost every other Montessori school within reach of here stops at kindergarten. Mills is about 3 miles from San Bruno, at 1400 Hillside Blvd. in South San Francisco.
Why families here choose it
Parents driving in from San Bruno tend to have already toured somewhere closer. What sends them up the hill is usually the same discovery: the closer school ends at five.
San Bruno sits just south of us, close to SFO and the airport shift patterns that come with it. The 7:30 am to 6:00 pm day was built for exactly these schedules — a school day that ends at 2:30 does not work for a family with an airport rota.
What Montessori elementary school at Mills actually is
Elementary Montessori is not preschool with more reading. The work gets genuinely hard — long research projects running for weeks, extended writing, mathematics carried from concrete materials into abstraction, and findings presented to the class. It opens with the largest possible frame, the story of how the universe, the earth and human beings came to be, and hangs history, geography, biology and mathematics off it, because six- to eleven-year-olds want the whole story rather than the chapter. Collaboration is the default rather than an exception: work is negotiated, argued over and produced in pairs and small groups.
- Continuity is the whole argumentA child who already knows how to plan a morning and finish what they start walks into a curriculum built on those habits, instead of one that has to replace them.
- Big questions, deliberatelyCosmic education: the frame first, the specifics second.
- One school, one commuteFamilies with a toddler and a fourth-grader do a single drop-off. The eleven-year-old is still in the building the two-year-old is starting in.

What San Bruno families ask about Montessori elementary school
- Will my child transfer to a traditional middle school all right?Yes — children leave at the end of fifth grade for public and private middle schools. The habits elementary Montessori builds are the ones middle school assumes and rarely teaches.
- Can a child join without a Montessori background?Yes, and children do. It takes a settling-in period — a child used to being told what to do next often finds the freedom harder than the work — and we would want to talk through your child specifically first.
- Is the Montessori elementary school different for families traveling from San Bruno?No — there is one program and one campus. What changes with distance is the schedule that suits you: families driving further usually choose the extended full day so they are not fighting the peak twice a day.
- How do we actually see the school from San Bruno?Tours run mid-morning, during the work cycle, year-round and by appointment. Twenty minutes at the back of a working classroom answers more than any page can. Book a morning or call the office.
- Is there a summer option?Yes — three optional summer sessions, enrolled separately from the school year. Some families from further out use a summer session as the trial run before committing to the drive in September.
- How is tuition actually paid?Annual tuition is based on a 180-day school year. You can pay it in one payment for a 5% discount, or in ten installments. Every rate and every fee is on the tuition page.
- Can we come part-time?Yes. Three, four or five days a week, and morning, full day or extended full day. Families driving from San Bruno more often lengthen the day than shorten the week, but both are offered.
