Full Ranking Detail
childcaremontessoripreschoolinfanttoddler
St. Mary's Montessori School - Rancho Cucamonga is an AMI-credentialed Montessori program serving infants through pre-kindergarten in the newer Etiwanda corridor of Rancho Cucamonga. Part of the multi-campus St. Mary's Montessori Schools system, it brings institutional stability and AMI recognition—the only AMI-affiliated Montessori network in the Inland Empire—with programs spanning Nido Community, Infant and Primary communities, and afterschool options. Meals are provided and state licensing is in place for both infant/toddler and primary classrooms. Strong Yelp engagement (70 reviews with 125 photos) reflects parent interest, though the absence of public Google reviews limits independent verification of day-to-day experience, and tuition aligns with AMI programs' higher cost structure, which may affect accessibility for some families.
