O’Dea was built by the Cathedral Parish in 1923, but is an independent Archdiocesan High School.
I believe that o'dea is a private high school so it is associated with the Catholic Church
When they go to Mass it is at the Cathedral, but I believe funding is through the school itself, but I could be wrong, the building I believe is owned the Diocese
Not sure but you can call the diocese.
