PHILADELPHIA, Penn., March 4, 2021—Nationalities Service Center (NSC) is proud to announce the recent promotions of four staff members. These ascensions are part of a long-term succession plan for the agency and will enable NSC to meet the rising demand for our services expected during the Biden administration.

“We have been strategic in identifying and investing in these extraordinary leaders who have consistently demonstrated the ability to show up and serve beyond expectations,” said Executive Director Margaret O’Sullivan. “By promoting our rising leaders to the management level, we are not only honoring their hard work and commitment, but we are also ensuring that NSC’s leadership team is strong and resilient as we prepare to enter our 100th year of serving immigrants and refugees here in Philadelphia and beyond.”

“These promotions are a clear investment in NSC’s future,” said Nan Feyler, NSC’s Board chair. “We can feel confident that NSC will be ready to meet the emerging challenges facing immigrants and refugees in the coming decades with exceptional competence and professional integrity.”
