In 1830, the German Theological Seminary of the Ohio Synod, later known as the Evangelical Lutheran Theological Seminary, was founded to meet the need for educating pastors in the Ohio region. It began in Canton, Ohio but soon moved to Columbus. In 1974, the decision was made that the Evangelical Lutheran Theological Seminary and Hamma Divinity School should consolidate. Hamma Divinity School dated to 1845 as the Theological department of Wittenberg College, in Springfield, Ohio. Trinity Lutheran Seminary, the merged institution, opened its doors on September 1, 1978. From 1978 until the Evangelical Lutheran Church in America came into being in 1988, Trinity was owned and operated jointly by the American Lutheran Church and the Lutheran Church in America. 
Trinity offers First Professional degrees of Master of Divinity (MDiv), Master of Theological Studies (MTS), Master of Arts in Church Music (MACM), and Master of Arts in Youth and Family Ministry (MAYFM), Master of Arts in Christian Education (MACE), and the Graduate degree of Master of Sacred Theology (STM) and a newly created degree with the Methodist Theological School in Ohio, Doctor of Ministry (DMin).
