Leadership at St. Luke's
Rev. Bradley Callaway Dyche
The Rev. Bradley C. Dyche was elected as Rector of St. Luke’s in early 2018 and officially began his role on Easter Day. Father Bradley originally hails from Enid, Oklahoma and his family’s wheat and cattle farm near there. Father Brad is a graduate of the University of Oklahoma. He then attained a Master of Divinity from the General Theological Seminary in New York City. He was a senior in seminary on 9/11 and actively worked at Ground Zero as a chaplain. He then served in the Diocese of New York for 16 years, his last call serving as Rector at St. Augustine’s Church, Croton on Hudson, NY. In all, he has been inspired by the vision of former Presiding Bishop The Most Rev. Edmond Browning who declared that in this Church, “There will be no outcasts.”
​
Father Bradley is father to Sheridan and husband to Frank De Jesus. Father Bradley enjoys cooking, hiking, kayaking, gardening and reading. He finds purpose in working with youth, in campus ministry, in education, and through pastoral care. Father Brad also has great theological interest in the works of Rene Girard concerning Mimetic Anthropology. He has served as President of Theology and Peace, a group dedicated to this theological work and asking how and why humans scapegoat others and how that relates to our concepts of God and Jesus.
Rev. Mark C. Witte
The Rev. Mark Witte is the curate (think: associate rector) and Tarleton campus missioner for St. Luke's.
Father Mark was born and raised in Dallas. Following his father, he earned his degree from the McCombs School of Business at the University of Texas at Austin. It was there, through the campus ministry, that he found the Episcopal Church in 2017 and began discerning a call to ordained ministry. During and after college, he worked in investment management at Merrill Lynch. He then spent two years living in an Episcopal Benedictine monastery in Omaha.
He obtained his Master of Divinity (M.Div.) from Virginia Theological Seminary. While there, he won the Episcopal Preaching Foundation Award for excellence in preaching. During the summers, he served as a hospital chaplain: first in a convalescent care facility, then in oncology and burn care at a Connecticut hospital.
​
Father Mark was ordained to the priesthood at St. Luke's in January 2026 by Bishop Brian Seage—the first ordination at St. Luke's in over 70 years.​
