Ner Aryeh did not close, they effectively broke away form Valley Torah High School, another great choice for kids that don’t exactly fit the Yeshivish mold.
All the yeshivas, high schools and educational institutions in LA are wonderful. Each seeks to educate a different type of student and creates a wonderful environment for them. A couple fo the schools that were not mentioned are Yavneh, located in Hancock Park in what is an incredible campus lead by an equally impressive administration, and Ohr Eliyahu which just moved in to the Hancock Park area and has an incredible campus of their own. Both of these schools are Nursery through 8th Grade.
LA is great, where else can you imagine kids going to spend the day at the park in the middle of January?
