We are pleased to present the rich history of Trinity High School. With more than 60 years of education, forming men of faith and character, we have a wonderful story to tell.
A History of Greatness
“The years you spend in high school are very important. They will affect your entire life.”
Monsignor Alfred Steinhauser, First Principal, Trinity High School
“Our mission from the day we opened has been to serve the broadest population possible. We are proud of the academic, geographic, racial, ethnic and economic diversity found in our school. Our doors will remain wide open for those who seek a caring community of teachers and learners, rooted in the Gospel message of Jesus Christ.”
Robert J. Mullen Ed.D., President, Trinity High School
Trinity first opened its doors in 1953, when Archbishop John Floersh anticipated the growth of Louisville’s eastern suburbs by choosing the site of Holy Trinity School, a former Catholic church and grade school in St. Matthews. That first freshman class numbered 106 students. With the Catholic tradition of teaching and learning firmly embedded in the buildings that became Trinity, the school is now more like a small college campus comprising about 1,200 students.
Our mission: Trinity is a Catholic, college-preparatory high school, forming men of faith and men of character.
