This school appears to have closed. We keep the entry because it is still listed as open across the web, and families deserve to know before they call.
No closure was ever announced, so the public record has to speak for the school. Its child-care permit record (DC24861) no longer appears on the city’s live register — the last inspection activity is dated 12 March 2025 — and the only permits at its address are now held by Tickle Toes Day Care LLC, a different company registered at 450 Kent Avenue in January 2025. Its own website, live and taking visits as recently as 12 August 2026, returned its hosting platform’s “Unknown Domain” page on 7 September 2026, and its Facebook page has not posted since April 2025. If you have information that corrects this — above all if the school is operating somewhere else — please tell us and we will update the page the same day.
williamsburg-montessori.org — dark since at least 7 September 2026 (wmsny.org, its email domain, frames the same dead page)Two things make this page safe to publish where a permit gap alone would not. First, there is positive evidence of a successor: a different company is registered at the address and holds the building’s child-care permits, at the full capacity the space supports. Second, the school’s own channels have gone dark — and we checked the domain that actually belonged to it (the one on its listings and on this profile), not a look-alike. Note the trap that nearly caught us: williamsburgmontessori.org, one hyphen away, is a live and enrolling school in Williamsburg, Virginia.
No newspaper reported a closure and the school published no notice, so there is no citable account and no exact last day. The dates above do not point to a single moment: the successor company registered in January 2025, the school’s permit record went quiet in March 2025 and its social media in April 2025, yet its website kept running and accepting tour requests into August 2026. A small school winding down quietly, and a website left on autopilot, would produce exactly this pattern. The school’s own corporation may still be active with the state; dissolution is not required on closure, so that would not contradict the rest. If it has relocated under another name we have not found it: the city register shows no other permit under the school’s name anywhere in the five boroughs.
Every major listing site still shows this school as open at 450 Kent Avenue, with photos, reviews and an “updated 2026” stamp. None of them is lying on purpose; listings are cheaper to keep than to check. If you found the school somewhere else and were about to call, this page is the answer you needed.

Until 2025 Williamsburg Montessori was an independent, waterfront Montessori on Kent Avenue with Spanish immersion woven through infant, toddler, 3–6 and lower-elementary communities. Parent sentiment on public forums skewed warm — a calm, loving atmosphere and a commitment to the method — with a smaller critical thread about communication during a leadership transition in 2024–25. Its self-description as “associated with” the American Montessori Society was never matched by a current AMS register entry on our checks. The adjudicated health-and-safety record below is kept for the historical record.

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.
