Vicenta Chávez Orozco, also known by her religious name María Vicenta de Santa Dorotea, was a Mexican Roman Catholic nun and the founder of the Servants of the Holy Spirit and the Poor. Orozco was admitted into a hospital in Guadalajara with pneumonia and there experienced a radical call to help others in the same hospital who were ill - she recovered and soon returned to fulfil this promise while later becoming a religious and establishing her own order in order to advance this mission.
