Founded in 1919 by Marion M.

Classes are kept small, ranging from twelve to twenty-two children depending on age, with at least two teachers in each room.
The school occupies five spacious classrooms across two buildings at 404 West 116th Street, situated between Columbia University and Morningside Park. The facility features two distinct outdoor play areas: a larger yard with climbing structures, a sandbox, and tricycles, and a smaller yard focused on natural loose parts and a mud kitchen. The Director, who has over twenty-five years of experience in early childhood programs, works closely with families to prepare children for kindergarten, guiding them through both public and independent school application processes.
The school’s strong reputation is reflected in its perfect rating and the diverse success of its graduates, who move on to a wide variety of public and independent schools throughout the city.
