Pre-Cursillo is the initial phase of the Cursillo movement, it is focused on building a foundation for the Cursillo experience and helping participants to open their hearts and minds to the transformative power of God's love.

During the Pre-Cursillo phase, participants engage in activities such as attending small friendship groups called "Group Reunion" who come together to be better friends and to form, strengthen and persevere a life in grace and Ultreya events to prepare themselves for the Cursillo weekend, where they will have the opportunity to experience a deeper encounter with God and their faith community.
