It would have been easy for families, alumni and supporters of Driscoll Catholic High School in Addison to accept the April 2 decision of the Christian Brothers of the Midwest to close the facility at the end of the academic year and move on with their lives. But they chose to pool their resources and make an effort to keep the school open. As of last week, members of a fundraising committee had raised more than $930,000 as part of a plan to save the school.
