See Yourself as a Tiger

Become the best version of yourself at Holy Trinity High School. Founded in 1910 by the Brothers of Holy Cross, we are a values-based Catholic school with a diverse and inclusive community.
We set rigorous standards in our college preparatory curriculum. Our AP and honors courses will prepare you to succeed once you graduate. Because education continues beyond the classroom, we will encourage you to also participate in fine arts, athletics and student life programs. To ensure your success, we created a personalized approach to education. Our exceptional faculty and supportive programs will meet you where you’re at and give you the tools you need to realize your full potential. We are small by design, so every student here is known and valued.
Your time at Holy Trinity is an investment that yields a lifetime of academic, spiritual and personal development. We are committed to making HT affordable for every admitted student and look forward to welcoming you here.
