Celebrating 70 Years Providing Excellence in Education in the Greater Harrisburg Area


Saint Margaret Mary School is renowned in the Harrisburg area for its academic excellence. For the past  70+ years our goal has been to provide the best possible Catholic education for every student. This goal is maintained through a dedicated faculty and staff committed to Catholic education. 


At the present time, St. Margaret Mary School maintains an enrollment of approximately 330 students. Our curriculum is based upon the graded courses of study developed by the Education Office of the Diocese of Harrisburg and approved by the State of Pennsylvania Department of Education.  Saint Margaret Mary School includes a full-day Kindergarten through 8th grade. Our early childhood program includes two days a week morning and afternoon for 3 yr olds as well as a three day a week morning and afternoon Pre-K program. Extended care is available before and after school hours from 6:30 A.M. until 5:30 PM.
