Sister was born in 1947 in Puerto Rico. In 1958, she came with her family to Connecticut. In 1996, she felt a call to be a missioner, at that time not thinking of being a Sister. With the help of her spiritual director she found the Glenmary Sisters. She became a Glenmary Sister Lay Missioner in July 1997. In 2006, she felt a call to religious life. She entered the Postulancy in 2007 and made final vows in 2012. In addition to serving in our Butler and Ohio missions, Sister has taken on many community responsibilities.
