Rosemarie Milazzo is a Maryknoll Sister from Brooklyn, New York, whose parents migrated from Sicily. After an assignment to Chinatown, New York, as teacher and principal, she was missioned to Africa -- first for language study and then to Kenya to serve as a lecturer at a Teacher Training College. Later she moved to the northeastern desert of Kenya, close to Somalia, as part of a team of Maryknoll Sisters who helped relocate people and acclimate them to the desert as part of a "reclamation project" for landless and homeless Kenyans.

Two hundred years ago this month, St. Rose Philippine Duchesne opened the first Society of the Sacred Heart school outside of Europe. To celebrate, the international order, now in 41 countries, is hosting a Global Day of Service for sisters, associates, employees, volunteers and students to take on dozens of service projects.

In a part of Guatemala City that lacks public health amenities, Sr. Sarah Mulligan runs a clinic where locals of all income levels can get affordable, quality medical care. Clínica Daniel Comboni offers several programs to meet locals' needs; some services empower local women, while others supplement children's education and nutrition.
