Holy Redeemer Parish was founded in 1910, originally as a mission of St. Jerome's Parish in Hyattsville. In 1912, the first church was built for the mission of Holy Redeemer parish. This structure remains basically in tact although it is now known as Fealy Hall. In 1922, Holy Redeemer was officially constituted as a parish by the Archbishop of Baltimore with Fr. Leo Fealy as its first resident pastor.

Fr. Fealy started on a school program soon after his assignment as pastor, using temporary facilities. In 1931, Holy Redeemer School began operation in a new structure, most of which is now the location of the various Parish Offices and meeting rooms. The school was staffed by the Sisters of Providence. In later years, the current school structure was built to house the offices and classrooms.

Overtime, the parish experienced a significant growth. As a result, a new church structure and convent were built and dedicated in 1954 by the Archbishop of Washington. It is this building in which we now celebrate our parish liturgies and it remains a tribute to the vision and dedication of Fr. Fealy.

The parish continued its growth and development reflecting the changes experienced in the Church as a result of the vigorous renewal prompted by the reforms of the Second Vatican Council. This was felt in both parish life and parish facilities. One of the visible changes occurred in 1982. Then the pastor, Fr. Donald Kelley, using his aesthetics talents, renovated the interior of the church into the present day worship atmosphere of spiritual simplicity.

These key events reflect in a visible way the constant faith of this Christian community. Nevertheless, the essence of our church remains in the life of the community, in the faith journey of those young and old members who are the body of Christ in this place and in this time.
