Greensburg Central Catholic High School is a Roman Catholic high school located in Greensburg, Pennsylvania and the Roman Catholic Diocese of Greensburg.HistoryConstruction of Greensburg Central Catholic High School began in the summer of 1958, only seven years after the founding of the Diocese of Greensburg. The first class of freshmen entered in September 1959, including students from as far east as Ligonier and as far west as Trafford.Bishop Hugh L. Lamb dedicated the building November 29, 1959, before an audience of 2,000 which included Governor David L. Lawrence as the featured speaker. This large audience was somewhat surprising given the extremely cold and snowy weather on the day of the dedication. In fact, according to the Greensburg Tribune-Review: The former Pittsburgh mayor (Governor Lawrence) not only had to abandon his automobile on a steep grade near the school but was forced to give his address in near darkness and without the use of a public address system. The latter inconveniences came about when an automobile went out of control, struck a utility pole... and wrecked the power system. At the time of Greensburg Central Catholic’s founding, six Roman Catholic religious institutes provided most of the faculty. The Sisters of St. Benedict were responsible for teaching languages; the Sisters of Charity, science and music; the Felician Sisters, mathematics; the Sisters of Mercy, English; the Sisters of St. Joseph, social studies; and the Vincentian Sisters of Charity, business. Lay teachers handled physical education.
