Following high school he earned an Associate's Degree from Rogers State University, and then completed a two year ministry internship at New Life Church in Colorado Springs, Colorado.

During his first job out of college, he was introduced to First Presbyterian Church in Tulsa at the invitation of then Middle School director, Jaclyn Miles. He volunteered with Pathfinders, the middle school ministry, and became a member of FPC that year.
It was during this time at First Church that James sensed his call to seminary. In 2007, he moved to Pittsburgh to pursue a Master of Divinity at Pittsburgh Theological Seminary. After completing his studies in Pittsburgh, he moved to Seattle to persuade his wife, Lindsey, to marry him. In August 2013, James returned to Tulsa in answer to the call to serve as an associate pastor at First Church.
James has had the opportunity to take mission trips to various countries including Mexico, China, the Ivory Coast, Malawi, Nepal, and Ethiopia. "I enjoy serving as the mission pastor because mission is the lifeblood of the church. In future ministry, I most look forward to developing missional partnerships with fellow followers of Christ that cross cultural, ethnic, racial, denominational, and national boundaries until the unity of Christ's one holy catholic and apostolic church becomes an observable reality."
James has been married to his wife, Lindsey, since 2012. Together they parent two beautiful children, Simeon and Abigail, daily working to bring them up in the discipline and instruction of the Lord (Ephesians 6:4). James enjoys being outdoors, whether backpacking, camping, hunting or pushing a stroller to the neighborhood park.
