As president, he is the chief ecclesiastical supervisor of the Synod and is responsible for the national program ministries of the LCMS, including the Office of International Mission, which calls and employs some 150 missionaries globally.

The effort was a success and led to the construction of a new branch of the Allen County Public Library and an office for the Fort Wayne Urban League in the neighborhood.
