I highly recommend them!
We have used Crossing Borders beginning in 2014 through now for all three of my children, and I highly recommend them! Over the years, we have seen them evolve both academically and in terms of extracurriculars. They are also responsive to parents. I also love the flexibility in terms of drop-off and pick-up scheduling, and in terms of language acquisition, when my oldest son graduated and went to another school, his Spanish teacher believed he was coming from a bilingual family, when in fact my husband and I do not speak any Spanish!
