Actually, there is one.
Wm. B. Eerdmans Publishing Company
Founded in 1911 and located in Grand Rapids, Michigan, Wm. B. Eerdmans Publishing Company is an independent publisher of religious books. They have a large range, including academic books and reference works in theology, biblical studies, and religious history to popular titles in spirituality, social and cultural criticism, as well as literature. They are primarily a print publisher with excellent distribution. My local independent bookstore regularly carries a number of their titles.
