On May 29, 2016 at the 11th Regular Session of the Southeastern Conference, Pastor Gregory O.  Mack was elected to serve as the sixth president of the Conference. Prior to his election, Pastor Mack served the Southeastern Conference for over 35 years as a pastor and Executive Secretary.


Elder Mack was born and raised in Miami, Florida. When he came of age, he accepted Jesus as his personal savior and was baptized into the Bethany Seventh-day Adventist Church. At the age of nineteen, Pastor Mack received God’s call to enter the gospel ministry and matriculated at Oakwood College, now Oakwood University in Huntsville, Alabama. Elder Mack graduated from Oakwood with an Associate of Arts degree in Communication and a Bachelor of Arts degree in Theology. Later, Elder Mack matriculated at Andrews University where he earned a Master of Divinity degree.


Beginning his pastoral ministry at Trinity Temple of Fitzgerald, Georgia; First Church of Hazlehurst, Georgia; Berea of St Augustine, Pastor Mack further honed his ministerial skills at Progress Village of Tampa; Thonotosassa of SDA; Salem of Pompano Beach; Ebenezer of Dania; Mt. Pisgah of Carol City; First Church of Riviera Beach; First Church of Royal Palm Beach, now known as First Church of Loxahatchee Groves; and Ephesus of West Palm Beach.


Under the tutelage of the Spirit and with the support of the leaders and members of his churches, Elder Mack successfully led the efforts to build and renovate several new churches and schools. In addition, to housing congregations and students, Pastor Mack initiated youth groups and invited thousands of souls into a relationship with Christ. In September 2008, Pastor was invited to serve as the Executive Secretary of Southeastern and in 2012 he was reelected to the same position. As the Executive Secretary, Elder Mack served as the interim pastor of Emmanuel in Deland for almost  a  year.


As the Executive Secretary, Pastor Mack’s portfolio included responsibility to provide oversight of legal, policy, membership, statistics, construction, Human Resources, and campground development. He also served as chair of the Building and Constitution and By-laws committees. Additionally, Elder Mack served as secretary of the Executive Committee, and Secretary to the Regional Retirement Screening Committee. The gifts, skills, abilities, and ministry experiences God vested in Pastor Mack prepared him for his current presidential role.


President Mack along with his team of fellow administrators, pastors, teachers, and other employees is determined to develop a culture within the Conference that is not focused on events but on the essential mission of the church. Southeastern must become and remain intentional about sharing hope and restoring wholeness to the people in the communities within the Conference’s territory and to the world.  


Pastor Mack has a passion to ensure that all Southeaster’s employees are treated fairly and that each church member receives excellent pastoral care to help them grow in their relationship with the Lord. His desire is to lead with godly compassion, integrity, and transparency.


Elder Mack is married to the former Jean Johnson, and God has blessed them with two wonderful sons, Clint and Darren.
