Sister Marta McDonnell’s current employer is Mercy Career and Technical High School in Philadelphia, a sponsored work of the Sisters of Mercy. In this position as a Sister of Mercy, she volunteers four days a week as Assistant Campus Minister and also serves as a translator for Spanish-speaking parents and guardians who apply for admission to the school. As a retired Theology professor of 18 years at Salve Regina University in Newport, Rhode Island, Sr. Marta hopes to bring those years of experience to Gwynedd Mercy Academy High School.

Sister Marta’s affiliation with Gwynedd Mercy is as a former Theology teacher for 12 years. During that time, Sr. Marta also served as Community Service Coordinator who directed approximately 2/3 of the student enrollment. With the assistance of several co-workers and parents, the ministry involved weekly visitation to the elderly and direct service to the homeless in center city Philadelphia. Additionally, the Service organization conducted regular food drives for city food banks. In 1991, Gwynedd Mercy Academy High School received the Blue Ribbon School of Excellence Award based not only on its superior academic accomplishments but equally in recognition of an outstanding commitment and involvement to service on a strictly volunteer basis.

Committee work for Sister Marta will include Student Enrollment and Student Experience; the former incorporating successful methods of recruitment and retention, the latter involving the Mercy charism of service to the poor, the sick, and the uneducated. Board members can be instrumental in setting policy, in our case, that students are aware of justice issues and seek to respond accordingly while reflecting on the systemic causes of injustices against the marginalized. Sister Marta is convinced that the unique idealism of teenage youth will respond to alleviate the needs of the disenfranchised; service to those in need is part of the DNA of Gwynedd students.

As a Sister of Mercy, Sister Marta anticipates a continuance of her work at the Academy and now as a Board member sees additional opportunities to empower the entire Gwynedd Mercy High School Community to promote the Critical Concerns of the Sisters of Mercy.
