1989 – The Foundation: Calle Güemes and Primera Junta
The Santísima Trinidad school was born from the need of a group of parents who were looking for a first class education for their children. It sought to create a school that combined the values of traditional education with the most modern tools of current technology. In its first year, the school, together with its thirty founding students, managed to lay the foundations for a true bilingual school. Since its creation, it has been entrusted to Our Lady of Schoenstatt and follows the guidelines of the Schoenstatt Apostolic Movement in the formation of its students.
