Rev. Dr. Marshall Zieman

Pastor/Head of Staff

marshall@pcoc.us

A native of the Midwest, Marshall grew up near Kansas City, graduating from Wichita State University with a Bachelor Degree in Business Administration. A Master of Divinity Degree was earned at Trinity Evangelical Divinity School near Chicago. A Doctorate of Ministry Degree was earned at Fuller Theological Seminary in California.

As newlyweds, Marshall and his wife, Becky, served as church planting missionaries in Spain. It was through the encouragement of Spanish elders that Marshall sought ordination to become a pastor.

Marshall’s first call as a pastor was to West Hills Presbyterian Church in Omaha where he was ordained in 1992. He served at West Hills as their Pastor of Children, Families, and Caregiving. Marshall served the next 20 years as an Associate Pastor at Highland Park Presbyterian Church in Dallas, overseeing the ministries of Children, Youth, and Outreach.

Always a proponent of world mission, Marshall has served as a Trustee of The Outreach Foundation of the Presbyterian Church. For the past 25 years, Marshall has travelled with church mission teams to Eastern Europe, Cuba, Central America, and Africa. He has conducted numerous teaching seminars in Hungary, Romania, Slovakia, Belarus, and Moldova on topics related to children’s and youth ministry and pastoral care. In recent years, Marshall has focused his travels in the Middle East, visiting and encouraging the Presbyterian Church in Lebanon and Syria, Iraq, Pakistan, and Egypt. Since coming to Church of the Cross, Marshall has participated in our church’s travels to minister with our partner church in the village of Gnozdovo, in western Russia.

Marshall and Becky have three young adult children. Natalia is married to Cade; they are architects living in Tucson, AZ. Suzanne works in Dallas for a Christian non-profit group, The Akola Project, providing employment and empowerment to women at risk, both in Dallas and around the world in Uganda. Ben also lives in Dallas, working as a landman in the oil and gas industry.

At Church of the Cross, Marshall serves as our primary preacher and worship leader, manages our busy staff, moderates the Session (our leadership body), and is the staff liaison to our Mission Committee.  Marshall loves jazz music, cherry pie, bar-b-que, and talking all things baseball, especially as it relates to his beloved Kansas City Royals.

Deacons

Email: deacons@pcoc.us

Elected by the congregation to three year terms, deacons minister to those who are in need, to the sick, to the friendless, and to any who may be in distress both within and beyond the community of faith.

The deacons of our church actively minister to others through…

  • outreach to homebound individuals
  • member visitation and support
  • correspondence and personal contact with members for significant life events
  • hospital visitation and delivery of flowers
  • provision of luncheons following the funeral services
  • coordination and provision of meals and other assistance during times of need.
  • support for various ministries such as Pantry Sunday, the Prayer Shawl ministry, recognition of graduating high school seniors, care boxes for young members who are away from home, and many special projects to support ongoing needs in the local and larger community.

The current moderator of the deacons is Joe Weaver.
