In 1963, under the direction of Father Emile Fossier, Holy Rosary Catholic School opened its doors to 42 students in the adjacent fire station to become the only Catholic school in lower Lafourche Parish.

Within a short time children relocated to the newly completed building that would service students from Our Lady of the Rosary Catholic Church Parish, its sister parishes of Sacred Heart, St. Joseph, Our Lady of Prompt Succor, Our Lady of the Isle, and anyone who accepted its philosophy and mission. Under the direction of Sister Claire Rodrigue and the Sisters of the Immaculate Conception the School continued to provide academic excellence and a moral foundation to instill a passion to model lives after Jesus Christ. 

During an economic peak in the early 1980’s the school flourished and housed 406 students from kindergarten through sixth grade. HRCS added several classrooms, a library and administration offices to its facilities. In the mid 1980’s the school lost the use of public transportation outside the immediate community and experienced a tremendous loss in population. The school addressed its enrollment concerns through several avenues including the addition of Friends of the Rosary tuition assistance, private busing, preschool, the expansion to the 8th grade and several enrollment promotions. HRCS continued to minister to each student’s uniqueness through structured devotion, expanded curriculum, and offer students the opportunity to reach their potential in a safe Catholic environment.
