School Reviews

5  
We have 2 children enrolled thus far, both starting from pre-primary, and we have to say that our children have really blossomed and love school and learning because of MSLG. We had originally sent our oldest to another nearby Montessori, but he could not adapt as they were not able to connect with him. He would end up crying every day for hours, and after 5 solid days of trying we withdrew. After switching to MSLG, he loved it there right away, and now is a bright, curious, social well adapted 4-year-old who loves to read. We could not have asked for more, and he is blossoming in his primary class. Our 2-year-old is in the same pre-primary that her older brother was in, and while she has a personality that is the polar opposite of her brother, she also loves school and looks forward to attending every day that we send her. Since we are bi-lingual, we appreciate the love and patience that the teachers and school have shown and their dedication to following "true" Montessori teaching. In a world where there are so many distractions, we appreciate the softer, quieter methodology.
