Saint Theresa School is located on the west shore of the Susquehanna River in Central Pennsylvania in the town of New Cumberland. Our school was founded in 1948 as the Little Flower School. We are an elementary and middle school educating preschool through 8th grade. The school was staffed by the Sisters of Mercy, and for 54 years there was a Sisters of Mercy presence at Saint Theresa School. In March 1998, Monsignor Robert Lawrence broke ground to build an addition to our school because of our growing enrollment. Today, our approximate enrollment is 350 students and have two classes per grade. We follow the Diocese of Harrisburg curriculum and align with their district guidelines. We are accredited by Middle States Association of Colleges and Schools, Commission on Elementary Education.
