Bishop O'Connell High School

Bishop Denis J. O'Connell High School is a faith-filled community of learning, rooted in a tradition of service and excellence. Founded by six local parishes in 1957, our school was built to serve the rapidly growing suburban Catholic population in the Washington, D.C. area. Today, our student body of approximately 1,200 students reflects the diversity of this community. The spiritual atmosphere at O'Connell is enriched by the presence of the Sisters, Servants of the Immaculate Heart of Mary, who have served the school population since its doors opened in 1957.
