Compañeros en Salud (CES) was founded as the Mexican sister organization of Partners In Health (PIH) and delivers high-quality, accompaniment-based care in rural, resource-constrained communities in Chiapas. CES is a multidisciplinary organization that provides primary healthcare across all three levels of care, along with social support services grounded in a preferential option for those most in need. Its work emphasizes patient-centered care delivered with dignity and guided by a strong commitment to equity.

As global health funding becomes increasingly uncertain and U.S.-based support for international health initiatives faces growing political and financial constraints, PIH has indicated that CES must move toward greater institutional, financial, and governance independence from its historical relationship with the U.S.-based organization. This transition raises complex questions about how CES can sustain its model of care, protect quality and equity, and establish a more independent organizational identity within Mexico and abroad, especially in the United States.
