Returning to the States, Sister Charlotte studied nursing and Clinical Pastoral Education, was a volunteer at a health center, and received her license as a registered professional nurse from the University of the State of NY Education Dept. She became Director of Nurses at the Maryknoll Sisters Nursing Home.
Responding to a request for nurses from the National Council of Churches when the war in Lebanon was growing worse in 1982, Sister Charlotte joined a group who were to reopen the Palestinian Hospital in Gaza between two refugee camps near West Beirut. During those three months, “Hard lessons came to those of us new to refugee nursing. One was that not all the psychiatrists in the Middle East could meet the needs of people traumatized by war.”
In 1983, Sister Charlotte joined the Maryknoll Sisters diocesan team in the jungle area of El Peten, Guatemala, traveling by jeep and hanging a hammock to give courses for women in nine parishes—Preventive Health, basic evangelization, courses to raise the dignity of women. When they turned this work over to their women Collaborators, Sister Charlotte worked as a nurse educator on an AIDS team in San Marcos and Quetzaltenango.
She became a member of the Eastern U.S. Region in 2007 and is a volunteer in the Housing Advocacy Committee in the twin parishes of Most Precious Blood and St. Anthony of Padua in Baltimore, MD.
