Meher Montessori-Altadena is one of the best preschools in the area. My daughter graduated this past June after spending 3 wonderful years there. There wasn't a day when she didn't want to go to school. The Montessori education she received there was simply amazing. She started to read right after she turned 4 and was already reading second grade level books before she started kindergarten. The school is small and therefore great for personal attention and care, but it also offers many things that you may not find even at the bigger schools. How many preschools do you know of that brings in petting zoos, pony rides, magic shows, and reptile shows to the campus? Meher offers these and other activities without any additional charges to the parents. The director has been there for almost 30 years and you can tell that she adores the children. Highly recommend this school.
