About MORNINGSIDE MONTESSORI SCHOOL ASSOCIATION

Morningside Montessori School Association (doing business as Morningside Montessori School) is an independent, nonprofit preschool located on Manhattan’s Upper West Side. The school delivers Montessori-based early childhood education for children from toddlers through kindergarten, emphasizing independence, hands-on learning, and social-emotional growth. Founded by parents in 1966, Morningside has operated continuously in the Upper West Side community and runs programs that include toddler and early childhood classrooms, a small-world language program, summer offerings, and community-focused events such as free rooftop playdates and family engagement activities. The organization maintains a small-school scale (roughly mid‑dozens of students) and a family-supported fundraising program (the Sunshine Fund) that underwrites teacher professional development and classroom enrichment.

Notable achievements

Longstanding history and continuous operation

Founded in 1966 by a group of local parents, the school has operated for six decades on Manhattan’s Upper West Side and continues to serve families from the neighborhood and surrounding communities.

Sustained program offerings across age groups

Morningside operates multiple program tracks—toddlers, young toddlers, an early childhood program (ages 3–5), language enrichment, after-school/adventure and a summer program—providing consistent early-learning pathways from roughly 1 year through kindergarten placement.

Donor-funded enrichment (The Sunshine Fund)

Annual gifts to the school’s Sunshine Fund support teacher professional development, classroom enrichment (for example music and movement), and program enhancements that would not be possible from tuition alone.
