First of all, what even is a Newman Center? Newman Centers (or Newman Clubs/Societies, or Catholic Clubs) are Catholic organizations at non-Catholic colleges and universities. They are places where you can go to Mass, receive the Sacraments, ask questions, and get to know other Catholics at your school.
In 2016, Bishop Olmsted asked the Franciscan Friars of the Holy Spirit to help him found a Newman Center at GCU.
The Friars met with Catholic students on campus, got to know the GCU Catholics club, and purchased the house at the southeast corner of 31st Ave and Camelback Rd. — about half a block south of the Colter Garage, across Camelback — renovated it and converted it into a chapel and a space to meet and hang out.
