Established in Los Alamitos in 1971, the Montesori Greenhouse school emphasizes a holistic and nurturing approach to students through the Montessori approach to education. One of two locations in Orange County, the Montessori Greenhouse School in Los Alamitos serves students in the "early childhood" age range of 2 years and six months old to five years and eight months old. Toddlers and elementary school-aged children are served at the sister facility in West Garden Grove.
The school offers a half-day program from 9am to noon and a whole day program from 9am to 3pm. Extended care is available. Reduced tuition is offered for students attending for fewer days during the week, and discounted rates are offered for multiple siblings enrolled at the school.
