They arrived in the United States in 1902 and the Sisters immediately began teaching in the parish school, living in a rented house provided by the parish.
In addition to teaching children in parochial schools, the Sisters began Vincentian High School (now Vincentian Academy) and began to serve the elderly, opening several nursing homes: the Vincentian Home, Villa de Marillac, Regency Hall Nursing Home and Adult Day Care and Marian Manor.
