Private Schools in Medellin - Recommendations?

My family is considering moving from the US (Florida) to Medellin in the next Protected content . We have two children in University who would remain in the US and two young children who would accompany us.

Question: for the young children (elementary age) - what are the recommendations for private schools? My children don't currently speak Spanish but we would like for them to learn as they grow up.

Appreciate any information and assistance. Thanks in advance

Doug
