Montessori School is the oldest day school in the city, established in July 1943. From a modest start, with only 3 children from ‘The Doon School’ campus, the school has progressedby leaps and bounds in almost every aspect. The trained educationist, Mrs Latika Roy, was the patron who received her training from Madame Maria Montessori herself and named it The Montessori School. The name continues till today.

Currently the school is located at Rajender Nagar, Dehradun. In March 2004 the new management took over the reins.
