While the rigorous study of Academics is important, Holy Trinity also recognizes the importance of taking time away from one's regular routine to focus on Christ's presence in one's life. As a result, the entire school attends a spiritual retreat each semester: an Advent Retreat in the fall and a Lenten Retreat in the Spring. In addition, the Senior Class attends an overnight spiritual retreat just for their class every year.

Holy Trinity utilizes the facilities at Cedarbrake Catholic Retreat Center in Belton for all of our spriitual retreats.
