Bishop Frank G. Tunstall
Superintendent
Dr. Frank G. Tunstall served twenty-three years as the pioneer pastor of Northwest Christian Center in Oklahoma City, leading the church through five building programs. He has also worked as editor in chief of publications and editor of the Advocate, the denominational official journal (now called Experience.) He taught Bible/Theology at Southwestern Christian University for many years, and served six years as Southwestern’s president.
In recent years he served eight years on the IPHC World Missions Board and 12 years as missions director of the Heartland Conference. He wrote the book, A History of World Missions, the First 100 Years, published in 2005. He also was elected to the General Executive Board of the denomination at the General Conference in Oklahoma City in 2005 and currently serves as a member of the IPHC board of control, the Council of Bishops. He is also a member of the Board of Regents of Southwestern Christian University and a member of the Executive Committee of the Board of regents. His newest book, Our Awesome Lord, is a Christology written to show what Jesus achieved and how He did it. Our Awesome Lord was released in September 2008 by Creation House. The Spanish version became available in May 2009.
Dr. Tunstall considers his chief credential for ministry is the altar he built in the woods while growing up as a teenager. That altar was his regular place of prayer during those years. “I know I met God as a boy in the woods,” he says. His lifelong love for the Word of God was also kindled in those years.
He holds earned degrees from Emmanuel College (A.A.), Methodist College (B. A.), Oral Roberts University (M. Div.), the University of Tulsa (M.A.), and Phillips University (D. Min.). He has also done study at the University of Oklahoma.
Dr. Tunstall and his wife, Lu, have three children, Dena, Franklin, Jr. and Derek (deceased), and five grandchildren. They have been married 45 years.
Peggy Henderson
Executive Secretary
Peggy has been the executive secretary to Bishop Frank Tunstall since the 2006 Quadrennial Conference of the Heartland Conference. Prior to coming to the Heartland Conference she served 'Pastor Frank' as his secretary at Northwest Christian Center for six years, and also as the church bookkeeper.
She graduated from the Heartland School of Ministry as the first student from the conference to graduate with an Associate Degree in Practical Biblical Theology from Advantage College through the School of Ministry. In June of 2009 she was ordained as a minister of the gospel.
Married to her high school sweetheart, she and Jessie will celebrate 43 years of marriage in June of 2010. They have two sons, two daughters, and seven grandchildren which bring tremendous joy to their busy lives.
Instead of slowing down as they head toward retirement years, they bought an acreage two years ago and took on the task of remodeling their home. This past December they started a business, Integrity Metal Recycling, with their two sons.
Having a heart for missions and for women, Peggy has taught in women's retreats in Kenya, Guyana, and Haiti. She and Jessie have traveled as team members on many church-building trips throughout South America, Central America and the Caribbean. Their desire is to become more deeply involved in mission work in the years to come.
Peggy and Jessie are members of Friendship PH church, where she serves on the Women's Ministry board and teaches the Pre-teen Sunday School class.
