It is a non-profit association, made up of several programs which helps different vulnerable populations with long-term projects; in order to contribute to a healthier and more equitable society with greater opportunities.

CAST supports one of these initiatives, El Pesebre de San Martin, which is a Pro-Life program. This project houses women of legal age who are pregnant, in a vulnerable and high-risk condition, giving them the opportunity to have a dignified and accompanied pregnancy, with access to basic services for the expectant mother and her child once born.
