When Bishop Peter L. Ireton (of the Richmond Diocese) decided to build and open a new all-male Catholic high school in Alexandria, he asked the Oblates of St. Francis de Sales to staff the school. The Oblates agreed and a rich, shared history was created. Oblate priests and brothers lived and worked at BI and their spirituality made a huge impact on students. Over the years, BI became a part of the newly created Arlington Diocese, became co-educational in 1991, and eventually grew to a population of 800 students. By 2008, the sole remaining Oblate – Principal Matthew Hillyard, OSFS – was transferred to another duty and BI became an Oblate Affiliated School.
The first lay principal, Mr. Timothy Hamer, and a group of teachers and staff formed the Salesian Discipleship Team. Made up of administrators, teachers, alumni, parents, and students, the Team forged a new relationship with the Oblates. They also wrote the Live Jesus Charter
as a guide to maintaining the charism of the Oblates at BI.
