She then served as a pastoral agent and candidate directress for the Sisters of the Holy Cross in Minas Gerais for eight years and organized community development for neighborhoods in need.

In 2005, Sister Mary began serving in formative roles as vocation director and novice director for the Congregation. Sister Mary currently serves in Congregation leadership as a general councilor.

Sister Mary earned her Registered Nurse Diploma from Saint Agnes Hospital School of Nursing in Baltimore, Maryland. In Brazil, she became board certified as an Enfermeira Padrao (Standard Nurse) in two states.
