 As of 10 August 2014, the principal of the college has been Pastor James Winderlich.Prior to its use as a seminary, the site was used for three different schools or colleges – the North Adelaide Grammar School from 1854–1882; Whinham College from 1882–1898, during which time a boarding house (now Hebart Hall) and a gymnasium-lecture hall (now the main part of Löhe Memorial Library) were built; and Angas College, owned by John Howard Angas, son of South Australian "patriarch" George Fife Angas and operated as an interdenominational missionary training school until the army took possession of the site for a repatriation hospital in 1916.In 1922 the United Evangelical Lutheran Church in Australia purchased the property for only ₤13,500 on the condition that it was used for Protestant Evangelical religious education.
