The BG Difference


Responding to the needs of the community since 1963.


The Brothers of the Sacred Heart initially arrived in Nashua in 1891, following the invitation of Father Millette, to take charge of the elementary school in St. Louis Parish. Most people simply refer to the school by saying “I went to the brothers on Vine St.” It was part and parcel of Catholic life in Nashua in the first half of 20th century. In the late 1950s, although a number of high schools for girls existed locally, no high school for boys existed. Bishop Primeau approached the Brothers of the Sacred Heart, already known for their educational work in Nashua, and asked that they take up the direction of a new school. The Bishop drew on the efforts of the parishes of the region to provide the initial land and funding to begin the construction.


Named in honor of Bishop Georges-Albert Guertin, third bishop of Manchester, the school would open its doors in 1963. In a partly-condemned, former orphanage building on Main Street, Bishop Guertin High School became a reality. More than one hundred freshmen formed that first class and their stories of that first year are the stuff of legends. Throughout that year, they would trek to the new building under construction and see the new campus slowly emerge. On September 9, 1964, Bishop Primeau blessed and opened the current site of Bishop Guertin High School on Lund Road. In 1992, responding again to the needs of the people of Nashua, Bishop Guertin High School became a co-educational institution.


Since its founding, BG has continued to grow and develop, and has always been faithful to that original mission of educating the whole person. Built on a dream made real through the hard work and commitment of families, students and Brothers alike, Bishop Guertin was built to challenge and form young people, to prepare them for life and to change for the better the world in which they live. The values of academic excellence, grit, and hard work, melded with faith, compassion, and commitment to others still echo through our halls. The spirit of Bishop Guertin reminds us of its humble past; guides us in the present; and inspires us to ensure a continuing future.

Mission and Vision Statements


Mission Statement


As a school of the Brothers of the Sacred Heart, Bishop Guertin High School seeks to live out the mission of our founder, Father André Coindre. That mission has not changed over the years, even though our ministries have evolved into many forms, always responding to the needs of each place. 


As a Catholic, co-educational, college preparatory high school, we, the Bishop Guertin High School community, serve the young people entrusted to our care.


Building upon the educational tradition of the Brothers of the Sacred Heart, we develop a school community which includes students, parents, faculty, staff, alumni, and friends.


Together we foster an environment of respect, compassion, and trust in which young people can grow and develop.

The formation of the spiritual, intellectual, creative, emotional, social, and physical dimensions of each person is made possible within a safe, supportive, faith-filled environment in which each person is known, valued, and treasured.


We accept the challenge of educating young people in a diverse and rapidly changing world.


Through a rigorous college preparatory curriculum and an extensive extra-curricular program, we promote life-long learning that is not only about success for today, but also about formation for tomorrow.


We — young people and adults alike — accept the ongoing challenge to grow as people of integrity who understand the responsibility to use our many gifts creatively in the service of others.


We strive to form tolerant, just, and involved men and women of faith who accept the task of building the Kingdom of God and of transforming, for the better, the world in which they live.


“To rescue young people from ignorance, to prepare them for life, and to give them a knowledge and love of religion, Father André Coindre, in 1821, founded the Institute of the Brothers of the Sacred Heart.
