In 1965, a group of educators, led by Professors Gilberto Padovese (1937–2011) and Hermes Ferreira Figueiredo (1938–2021), launched an educational project by offering a preparatory course aimed at admission to the highly competitive public middle school system. The resources obtained through this initiative enabled the construction of the first four classrooms—a physical and symbolic milestone marking the beginning of a journey committed to education.
With the structure completed, Colégio Cruzeiro do Sul began its activities in 1966, initially offering middle school education for children and adolescents. Over the years, the institution expanded its scope, incorporating elementary and high school courses, establishing itself as an educational reference in the region and laying the foundation for what would become, decades later, one of the largest educational groups in the country.
