Our Vision

We aspire to be regarded as the preeminent high school in central Pennsylvania.  We will be known as a school that epitomizes excellence in all our endeavors; a school that inspires loyalty and passion among all constituents/customers past and present; a school that stands for integrity, dignity, and class in every facet of what we do; a school that lives the Gospel of the Catholic church and embraces the call to welcome all members of God’s family; a school whose culture is deeply embedded in the power of prayer.

Our Catholic Identity

Our Catholic Identity is the core of who we are and what sets us apart from other schools. We, at Trinity, work hard to foster an environment that will help students grow spiritually and learn how to be a guiding presence in their parish, family, and community. Campus Ministry strives to provide students the opportunity to grow in relationship with God, their family, and their friends, the opportunity to see the face of Christ in all those around them, the opportunity to serve God through the service of neighbors, and the opportunity to apply knowledge learned in Religion class to the world around them.

Board of Directors

Trinity High School has three layers of governance.  First is the Diocese of Harrisburg Secretariat for Education, second is the school’s Board of Directors, and third is the Principal.
