A waterfront, Spanish-immersion Montessori on Kent Avenue — serving children from infancy through lower elementary, and an AMS member.
The Montessori approach and waterfront program are well described, but tuition isn't published and leadership has changed recently — so request current fees and confirm the director and lead-teacher credentials for your year. Why this matters →


Williamsburg is North Brooklyn's former industrial waterfront turned family neighborhood — converted brick warehouse lofts, an East River esplanade with Manhattan skyline views, and quick access on the L and J/M/Z. The school's Kent Avenue home sits right along the water.
Williamsburg Montessori is an independent, waterfront Montessori on Kent Avenue serving children from about three months old through lower elementary (around age nine), with Spanish immersion woven through the program. It is an AMS member (a membership rather than the higher bar of accreditation).
Nido/infant and toddler communities, a 3–6 Primary, and a lower-elementary program, all with Spanish immersion. The Kent Avenue location gives the school a distinctive waterfront setting.
Tuition is not publicly posted — the school shares fees on request. Ask early and factor in that infant/toddler care is typically the most expensive band. Compare with peers on the tuition page.
Community reports describe a newer director (referred to as "Becky") who took over around 2024–25 and is credited with steadying the school. Because that's second-hand, confirm the current director and lead-teacher Montessori credentials directly when you inquire.
AMS membership signals a Montessori orientation but isn't the same as AMS/AMI accreditation. Parent and review-site comments generally describe an authentic, peaceful Montessori environment — see our authenticity guide for what to verify on a tour.
Sentiment skews warm — a calm, loving Montessori atmosphere — with a smaller, more critical thread around communication and leadership during the recent transition. Both are below.
Signals from public parent forums, listservs and review sites (Park Slope Parents, GreatSchools, Yelp). Forum chatter is opinion — often anonymous — so take it with a grain of salt.
Note: we've left out the most vivid negative specifics (a police-station field-trip claim and "vice principal / parent coordinator" wording) because that vocabulary points to a public school and we couldn't confirm it refers to this private program. The remaining concern above is a minority view; weigh it against the recent leadership change and judge for yourself on a visit.
As an independent Brooklyn Montessori, inquire directly and tour — timelines are more flexible than the ISAAGNY private-school calendar. For candid local research, Brooklyn parent communities like Park Slope Parents are useful. See our admissions timeline and planner.
