“How hard it is to say good-bye! No words can express how thankful we are for these past three years of wonderful experiences at the Montessori School Geneva. And all thanks to your loving dedication to our children. You lead the best school in the world! We will miss you tremendously but leave with only the most loving memories.”


“My son is having such a wonderful time at your school, so it is with great regret that we have to tell you that we are moving to another country.”


“I can’t thank you enough for the wonderful year my daughter had attending the Montessori School Geneva. Her eyes lit up anytime she would talk about her class and her wonderful teachers”


“Thank you for another wonderful year. Our son learnt so much. He is always very happy to go to school, which means the world to us. We wish you a lovely and well deserved Summer Holiday, see you next year!”

At the Montessori School Geneva children will learn by doing. We help them develop their movement coordination, self-confidence and independence through their own activity with the Montessori material. We try to respond to each child individually by following his own rhythm and interests.

The School is situated on the left bank of Geneva. Since September 2013 the Montessori School Geneva is located in the residential area of Curé-Desclouds (Thônex), in a brand new minergie building. The school occupies the spacious and very bright ground floor.

Possibility to park in front of the school. Access by bus number 5, 25 and 37.

We provide enriching and fun activities which enable the individual child to explore and learn about many aspects of the world around him.
