Early 1950s 
Three Dominican Sisters from Adrian, Michigan envisioned a school where students would receive an exceptional education, centered around Christ. Trinity Catholic School was then led by six principals from the Adrian Order (O.P.) and the Franciscan (O.S.F.) Order. The Sisters resided in a home across the street from the school and eventually a convent was constructed, which now overlooks the campus as the John Neumann Retreat Center.

1952
Trinity Catholic School opens its doors as Blessed Sacrament School to 102 students in 1st through 4th Grades at our present location on Miccosukee Road and Brevard Street. 

1953
Enrollment doubles just one year after opening.

1954-1976
Trinity Catholic School continues steadily growing under the jurisdiction of the Diocese of St. Augustine.

1977
The Diocese of Pensacola-Tallahassee was formed under its first Bishop, Rene Gracida, and Blessed Sacrament School was renamed Trinity Catholic School.

1978-2000
As the only Catholic Elementary School in the area, the school remains a ministry of Blessed Sacrament Church, but is financially, spiritually, and liturgically supported by the parishes of Blessed Sacrament, Good Shepherd, St. Thomas More, St. Louis and St. Eugene’s Chapel.

2001
An extended day care program was initiated. "Beyond the Bell" has become a strong after school program offering Trinity students various enrichment activities. 

2007
Then Principal Janet Gendusa established a Pre-Kindergarten 3 year old program in response to a growing need for a quality early childhood program built around Catholic standards. Now students can boast of 11 years of Catholic education when they graduate from Trinity Catholic School.

2017
Trinity Catholic School celebrates 65 years of Catholic education in Tallahassee, Florida. 

Today
Trinity Catholic School enjoys a rich history and tradition of excellence. For over 70 years now, our graduates have made lasting contributions to the greater Tallahassee community and beyond. Our alumni return to campus when they bring their own children here to experience the same educational opportunities they received.
