Anyone have experience with Realm charter high school?

My son really needs to transfer out of his large Oakland public high school because of a major cyberbullying incident that has devastated his trust in the environment. It is August and we need a high school for an incoming 11th grader. Tall order. The only smaller high school that has room is Realm Charter High School. Does anyone have recent experience with that school? Does anyone have recommendations for a supportive, smaller school for a kid who has anxiety/depression issues? Thanks.
