Williamsburg Montessori

A waterfront, Spanish-immersion Montessori on Kent Avenue — serving children from infancy through lower elementary, and an AMS member.

Accreditation check
Williamsburg Montessori’s own site says it “will obtain accreditation and certification from… NAEYC and is associated with the American Montessori Society (AMS)”, and that its lead teachers are certified through MACTE-accredited programmes — a teacher credential, not a school membership. It does not appear in the AMS register (checked August 10, 2026 by name, ZIP and city sweeps, not geo alone). A former AMS listing now returns 404. Status: lapsed or inaccurate as currently stated.

Amber  Staff transparency

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 →

Stylized illustration of Williamsburg, Brooklyn: brick warehouse lofts with large factory windows and a rooftop water tower beside the East River and the Williamsburg Bridge

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.

Overview

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).

Programs & ages

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 2026–27

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.

Leadership & staff

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.

Accreditation & authenticity

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.

What parents say

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.

Heard around town

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.

"You can feel the love and peaceful vibe from the moment you walk in." GreatSchools / Park Slope Parents
"WMS is thoroughly committed to practicing the Montessori method with integrity and authenticity." Yelp
New director "Becky … took over about a year ago and she's really gotten the school in order." Park Slope Parents · paraphrased
A minority, more critical account cited poor communication and leadership during the recent transition, and one reviewer claimed a number of families left after pre-K. Yelp / PSP-indexed · minority view

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.

Admissions

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.

Cited under Article 43 (school-based child care), not Article 47.

For comparison: across all 18,161 DOHMH child-care cases heard at OATH, 63.1% were sustained, 21.3% ended in default and 13.1% were dismissed. Most citations concern records, repairs and paperwork — staff immunisation files, premises upkeep, sink water temperature, background-check timing — rather than incidents involving a child.

The record gives the rule cited and the result, but never the inspector’s narrative — the charge text always reads “see attached NOV”. Outcomes can change on appeal. Something wrong? Tell us.
