Mark Koller

Mark is a doctoral student in Historical Theology at Puritan Reformed Theological Seminary and is studying under the supervision of Dr. Adriaan Neele, Dr. Bob McKelvey, and Dr. Stephen Myers. His research focuses on the writings of Samuel Rutherford (1600-1661), specifically his ecclesiastical works and his doctrine of the church.

Mark serves as the church planting Pastor of the Dallas Reformed Presbyterian Church, a congregation of the Reformed Presbyterian Church of North America (RPCNA). The Reformed Presbyterians are the direct descendants of the Scottish Covenanters, a primary interest of Mark’s research.

Before coming to PRTS, he completed his Bachelor of Science at the University of Arkansas for Medical Sciences and his M.Div at Whitefield Theological Seminary of Lakeland, Florida. Mark has worked in the field of Cytogenetics for twenty-four years, working in a clinical laboratory setting and with various research projects related to the study of blood cancers and tumors.

Mark is married to his wife Amy and they have three children (Drew, Rachel, and Kate).

“Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.”
