Arlington Catholic High School was founded in 1960 under the direction of Monsignor Oscar O’Gorman. It was built by the parishioners of St. Agnes Parish in Arlington, and originally staffed by the congregation of the Sisters of St. Joseph. Since its inaugural class of 1964, Arlington Catholic has graduated over 9,000 students. Our alumni share the common experience of excellent preparation for study beyond high school and for making a difference in the world. This tradition remains strong today
