Our History

Trinity High School can trace its roots back to 1886, when St. Joseph High School for Boys opened on Lowell Street in Manchester.

At the invitation of Bishop Denis Bradley, the first bishop of Manchester, the school was staffed by the Brothers of the Christian Schools, an international order of religious brothers founded in France in 1679 and dedicated solely to Catholic education.

Despite its small size, St. Joseph was a dynamic Catholic school which produced many prominent alumni and fielded outstanding athletic teams. St. Joseph High School teams regularly defeated much bigger high school teams in Manchester, Nashua, and Concord and were thus nicknamed the Giant Killers.

Needing to expand, St. Joseph High School moved to a brand new building at 581 Bridge Street in Manchester in 1951 and was renamed Bishop Bradley High School. At the same time, the school nickname was changed to the Pioneers to honor the Christian Brothers, who were pioneers in Catholic education, as well as Bishop Bradley, the school's namesake. Bishop Bradley was the premier Catholic high school in Manchester graduating thousands of young men, many of whom went on to notable leadership roles in the city and in the Church.

In 1970, changing demographics in the city and the church would necessitate Bishop Bradley High School's merger with two other Catholic high schools in Manchester - Immaculata High School and St. Anthony's High School. The new co-ed Trinity High School was located at the Bridge Street location (and for a time at the Immaculata building located up the street) and was administered by the Christian Brothers, the Sisters of the Holy Cross, and the Sisters of Mercy. With declining vocations to the religious life, more and more lay people assumed leadership and teaching roles in the school and the first lay principal, Mr. Thomas Spaulding, was appointed in 1974.

Today, Trinity High School carries on the legacies of all the Catholic high schools that once existed in the city of Manchester, the names of which are proudly adorned in our gym.
