Our Team
"We believe that enabling our children to lead their best lives means that schooling has to be transformed for the 21st century. When we discovered the freedom of an Acton Academy educational model, with its roots in Montessori, defined by self-paced learning, offering the opportunity for students to discover their most precious gifts, and to develop the character of a real hero, we became determined to make Acton Academy El Salvador a reality not only for our children, but for yours too."
