There are more Catholic schools than that in the west:
Notre Dame de Namur (it is closing)
Dominican (historically Catholic)
Mount St Mary’s
St Mary’s College of California
Holy Name
Marymount California College
Thomas Aquinas
JohnPaul the Great
Marylhurst (oregon)
St. Martins (washington)
Catholic schools are traditionally urban because that’s the population they were trying to serve. Many Catholic schools have pretty good basketball teams because, again, they were trying to serve the neighborhoods they were in and wanted a way to get kids involved that was cheaper than football.
