History
The Sacred Hearts Fathers, under the direction of Father Leonore Fouesnel, SS.CC., established Saint Anthony parish school in 1883. On September 5, 1883, Brother Thomas Eichorn, Francis Marx, and John Parr of the Society of Mary (the Marianists) arrived in Wailuku and initiated the long years of service under the leadership of Mary, the Immaculate Woman, to whom the Brothers of Mary are especially concentrated.

The first of three Brothers opened the school September 10, 1883. The Franciscan Sisters of Syracuse, New York, under the direction of Sister Mary Antonella, OSF, staffed the girls’ school beginning in 1884. The Maryknoll Sisters of Saint Dominic, with Sister Mary Celeste as the first principal, began teaching at Saint Anthony in 1928 at the request of Bishop Alencastre. Dedicated layman assisted in the teaching beginning September 1958.

Chaminade and Damien Hall were erected in 1925 when the Very Reverend Justin Van Schayk was pastor of Saint Anthony Church. It houses the school administrative offices as well as ten classrooms and two computer labs. Maryknoll Hall was built in 1940 and encompasses eight classrooms, an art studio, and counseling offices.

Marian Hall, the cafeteria, was built in 1959 while Father Robert Schoofs, SS.CC., was pastor. The Bishop Sweeny Memorial Library was built in 1965 while Father Walter Demeyer, SS.CC. was pastor. The library was renovated in 2002 and now houses three computer labs, the Harry C. and Nee Chang Wong Media Center, the Fairway Media Center, and the business lab.

The science facility was completed in 1967 when Father Alfred Vann, SS.CC. was pastor. The science labs were completely renovated and rededicated as the E. L. Weigand Science Building in 2005.
In 1968 the school became coeducational and the junior high was added in 1971.

Today, Saint Anthony Junior Senior High School is the only Catholic High School on the island of Maui. It is a diocesan sponsored coeducational institution under the Bishop of Honolulu, governed by the Saint Anthony School Board, and sponsored by the members of the Society of Mary. It is staffed by laymen and laywomen, Marianist Priests and Brothers, and the Sisters of Saint Joseph of Carondelet.
