Dennis Castillo

Dr. Dennis Castillo joined the St. Mary’s faculty in 2022 after more than twenty years of teaching at other Catholic colleges and seminaries. He serves also as St. Mary’s Associate Dean of Assessment and Accreditation.

Dr. Castillo enjoys all periods of Church History, seeing in each one the challenge of being a disciple of Jesus to a world in need of the Gospel. His own research has been in the fields of American Catholicism and the history of Malta. Dr. Castillo has two current writing projects. One is a history of the Catholic Church’s response to the cholera epidemics in the nineteenth century. The other is a study of the Knights of Malta and the order’s transition in the twentieth century from being a military order back to its original hospitaller charism.
