Introduction: The rezadora, a lay spiritual leader, provides support to Latino families as they provide end-of-life (EOL) care for loved ones. The purpose of this study was to learn about the work of the rezadora in Guatemala as a resource for Latinos with serious illness in the United States. Methods: An ethnographic exploratory case study was conducted during summer 2018 in rural Guatemala. We interviewed three rezadoras who resided in two villages. The study yielded two cases, the single case and the paired case, which allowed for a holistic view of how the rezadora serves the community. Results: Content and thematic analysis led to two themes: Essence of being called and Power of prayerful song. Essence of being called was represented by the prominence of the rezadora and their perpetual faith work. Power of prayerful song was characterized through the mission, customs, and the presence of the rezadora. A good death was aided by the rezadora in this context. Conclusions: As the Latino population ages in place, the need for palliative and EOL care services will increase. Lay spiritual leaders could enhance the palliative care teams in these communities and improve the quality of life for Latinos with serious illness.
