Since 1989, PIH has collaborated with EAPSEC to improve medical infrastructure in the region and to recruit and train hundreds of "promotores." Over the past two decades, EAPSEC has partnered with dozens of indigenous and rural communities throughout Chiapas to develop local health capacity. Recent work has focused on a network of communities in the area of Huitiupan in the highlands and around Amatan. EAPSEC is dedicated to helping communities build self-sufficiency and counts many successful community health groups throughout Chiapas among its "alumni."
