With thirty years of pastoral experience, Rev. Dr. Frederick Stassner was called by the church in 1890. He oversaw the building of a parsonage on the east side of the building and instigated the founding of “A Young People’s Society of Christian Endeavor” as well as a “Junior Society,” both of which instilled a vision of servant leadership in young people. 

In 1896, Rev. Frederick C. Nau became the church’s sixth pastor. In order to secure funds to build more space for the growing congregation and Sunday School, the church was legally incorporated in 1897 under the new name, “The First German Reformed Church of Canton, Ohio.” In 1899, a major addition to the west end of the building was dedicated, the basement was remodeled as a social and dining hall, and memorial stained-glass windows were added to the sanctuary thanks to the Frauenverein, a society of German-American women organized to provide relief of widows, orphans, and the sick.

1902 saw the creation of “The Woman’s Missionary Society,” and in 1906 Andrew Carnegie contributed half the cost toward the purchase of a new organ, with the other half coming from memorials and congregational donations.

Rev. Dr. Theodore P. Bolliger was called by the church in 1907, becoming the church’s seventh pastor. Rev. Bolliger’s pastorate began with the addition of English services on alternate Sunday mornings.
