Joachina was born in Barcelona in 1783. She married Theodore de Mas in 1799 and bore him nine children before being widowed in 1816. Then in 1826 she was prompted by God's Spirit to found the Congregation of Carmelite Sisters of Charity, which spread throughout Catalonia, establishing houses for the care of the sick and the education of children, especially the poor. She was greatly drawn to contemplating the mystery of the Holy Trinity. Her spritual life was marked by prayer, mortification, detachment, humility and love. She died at Vich in 1854.
