Our Parish community began in 1906 with Masses first said in homes of Catholic families.  St. Charles was established as a mission in 1908 and the church was dedicated on August 8, 1908 by Bishop O'Donahue of Indianapolis.  The parish membership was then 15 families.  The parish will be 96 years old this August.

The Church building was erected on land donated by Mr. and Mrs. Newt Peters.  Much of the work and materials were donated by parishioners, the numbers had grown to 25 families.  The altars were donated by Mrs. Rudolf of Oldenburg and the stained glass windows were donated by the Sisters of St. Francis of Oldenburg.

Our Parish Community remained a mission, served by neighboring pastors until 1948.  In that year, St. Charles obtained the status of a parish and was served by Fr. Burgert, our first pastor.  He built the present rectory in 1948 and the parish hall in 1949.  At that time the congregation numbered around 50 families.

Most Rev. Joseph W. Tobin, C.Ss.R., Archbishop of Indianapolis., decreed St. Pius, Sunman to extinctive union with St. Charles Borromeo on December 1, 2013 and all St. Pius parishioners were welcomed into the St. Charles Parish Family.  Currently there are 217 families registered in the parish.
