The growth of Our Lady of the Sacred Heart Parish from a mission church to the present complex of building and community of people has been generated by three dedicated priests. Rev. Msgr. Nelson Baker, Rev. John S. Doyle, and Rev. Msgr. Dino J. Lorenzetti. Each in turn with faith, hope, and vision served as father and confessor to this parish family. Our forefathers were settlers of Irish and German decent, joined by Italian immigrants, employed by the expanding steel companies. Their requests in 1920 prompted Fr. Baker our founder, to construct a simple wooden church near Lake Avenue, in the area referred to as "The Hill". This Mission Chapel at Windom was also used as a school, housing 45 students and staffed by Brothers of the Holy Infancy.

On April 1, 1929 the mission church was completely demolished by a tornado. A new brick building, replacing it , was dedicated on October 12, 1929. For the ensuing thirty years, this building (still standing) was the center of worship. A succession of assistant priests from Our Lady of Victory traveled each week to minister and care for the spiritual needs of the people. In June of 1949, the church was raised from mission status to a parish, entitled Our Lady of the Sacred Heart.
