Oak Knoll Kinderhaus is an Association Montessori International accredited school. This La Cañada campus provides instruction for elementary students up to age 12 while toddlers as young as 18 months and pre-school children attend the Oak Knoll Kinderhaus on Lake Avenue in Pasadena. At this traditional Montessori school, children learn and explore inside and outside the classroom. They may plant and harvest flowers and vegetables, feed the birds and squirrels and bring classroom equipment outside.
