School Reviews

Hi,We are looking for a nice, friendly school, with up to 18 students in a class. Boys and girls. Preferably international diverse students, where a foreigner does not feel like a stranger and where you can make friends. We used to live in Manhattan for 5 years and just last year we moved to California. Our school was not a good fit for our daughter.
