26 January 1955 the Brothers in Buenos Aires (Argentina) started with what is now called the Lyceo Nuestra Señora de Lujàn.
In 2003 the Obra Misericordista of Buenos Aires took over the Damasa school from the sisters Zelaya de Saavedra. That school now became part of the Lyceo N. S. de Lujàn.
In the Colegio Nuestra Señora da Lujàn and the Colegio Damasa there is an infant school and a primary school as well as a secondary division. Both institutes work together.
From 1994 till now the Brothers are active in the Social Centre Tabor in Buenos Aires (Argentina) Santiago del Estero.
