We love this High School! Three of our children have attended this high school. The students not only learn their faith, but academic rigor and to give back and serve in their community. A small, Catholic high school also allows a student to try all the sports and activities.

Holy Trinity was an answered prayer for our family after we moved out of DFW. After being in an excellent classical charter, our oldest son experienced bad language and out-of-control classrooms for the first time. As we prayed for guidance, I met two families who told me how much they loved Holy Trinity for their teens without my even asking. At first, I thought there was no way we could manage the cost. I am so glad that we took the first steps anyway. Our freshman son has quickly developed a community of friends who also value their Christian faith. We love that his teachers foster meaningful conversations and deeper learning in their classes. HTCHS also genuinely values the arts and extra-curricular activities. Financially it isn`t easy, but we have always felt supported and are so grateful for the generous financial aid that has given our son a faith-filled and academically challenging environment to mature.

HTCHS has been a great school for our children. They have gained Christian leadership skills and their Catholic faith has blossomed by the support of the school. It is refreshing that Holy Trinity teaches and supports the same Catholic and educational values that we tech at home.
