Gimnasio La Colina has its origins in the preschool institution "Las Casitas", founded by Rosario Iragorri Casas in 1975. At that time, the school had 12 children and was located in the western part of Cali. At the request of parents who had their children enrolled in Las Casitas, Rosarito (as she was affectionately called by people who knew her) decided to continue her educational project by starting an elementary school with the intention of offering our city another educational alternative. In 1981, the founder's husband bought a piece of land in the Menga neighborhood. That property is where the Gimnasio's preschool area is today.
