Trinity's vision and pastoral care is led by our pastors and elders. Mercy ministry is led by our deacons. The staff supports that vision. The members carry out the work of ministry in their areas of influence.

PAUL DESLAURIERS
Elder
Paul is a Massachusetts native brought to the south via the US Navy (1972-1976) and by God’s providence he met Joann, a teacher on vacation in Pensacola, FL and was married (1975). The Lord used Joann to led Paul to faith where he became a Christian in 1976. Both Joann and Paul join the PCA that year and worshiped at McIlwain Presbyterian Church. Following his move to Hattiesburg MS to pursue a Ph.D. in chemistry, Paul and Joann started their family where they were blessed with the birth of Anna (now Anna Keltner) and after moving to Conroe Texas in 1984 to take a job with Penzoil (Woodland TX), they were blessed again with the birth of Hailey (now Hailey Shaw). Pretty amazing testimony of God’s grace in light of the fact they were told they would never be able to have children! Now they are proud grandparents of four grandsons. In 1989 the DesLauriers Family moved to Oklahoma where Paul took a job with Phillips Petroleum and Joann continued to teach. Paul is currently a self-directed, Research Fellow at Chevron Phillips in Bartlesville, OK., and Joann is now retired from Oklahoma State University. Paul and Joann have been active in the church where ever God has lead them and over the years Paul has been called to serve leadership roles in several congregations including:
- Ordained Deacon at First Presbyterian Church, PCA, Hattiesburg MS (1983-1984)
- Ordained Elder at Spring Cypress Presbyterian Church, PCA, Spring Cypress, TX (1986-1988)
- Ordained Elder at Westminster Presbyterian Church, OPC, Bartlesville, OK (1990-2005)
- Ordained Elder at Christ Presbyterian Church, PCA, Tulsa, OK (2007-2014)
- Member of Temporary Session for Trinity Presbyterian Church, PCA, Owasso (2011-2013)
Paul and Joann are currently members of Trinity and are active as teachers and community group leaders.
NATHAN KELTNER
Elder
Nathan Keltner is a husband and father, life-long Oklahoman, and 2012 Owasso transplant. He works in the Information Security field. He came to faith as a young child growing up in Bartlesville, OK, and over time, God was faithful in maturing Nathan's belief through placing instrumental believers in his life. While in his Senior year at the University of Oklahoma, he met his future wife, Anna, who deepened his commitment to Christ and introduced him to the Presbyterian Church in America. They were married in 2005. Through churches in OKC and Dallas, Nathan was mentored by many wonderful believers and grew to treasure Christ's church. Nathan and Anna moved to Tulsa in 2008 and joined Christ Presbyterian Church, where they met the Parkers, the Phelps, the Carinis, and many others, which God used to bring him to Trinity Owasso in 2012. Nathan enjoys working with his niche in Information Security, reading, trying and failing miserably at sports, and spending time with his three hilarious boys, Asher, Judah, and Caedman, and wife, Anna.
JASON KREIDER
Elder
Jason came to a saving faith at age 6 after his family’s narrow escape from a house fire. As he has grown in the Lord, he has found that God uses “mini-fires” in his life to reveal his weak faith, idols, and rebellious heart but more importantly how God’s “power is made perfect in weakness. Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me” 2 Cor. 12:9. Jason completed his doctorate in Chemistry at OSU and they moved to Boiling Springs, SC where they first attended a PCA church. They now live north of Bartlesville with their four children Noah, Levi, Jesse, and Elianna. In his spare time, Jason enjoys Trinity's Bartlesville Community Group, brewing beer, working on his farm, and praying about God's timing for a future church plant in Bartlesville.
