Since 1994, Reverend Sammie D. Simmons has been the pastor of St. Mark Four Bridges Missionary Baptist Church located in Sumter, South Carolina. Under his pastoral leadership, St. Mark 4(B) has experienced dramatic growth, not only in membership, but tremendous growth spiritually. Pastor Simmons has established several innovative ministries such as: Women's Ministry, Kingdom Knights (Brotherhood), New Members Class, Tree of Life (Tutorial Ministry), Youth Development, Career Advancement Ministry, Junior Missionaries, Food and Clothing Ministry, Prison Ministry, Singles Ministry, Marriage Ministry, Evangelistic Ministry, an Administrative Division, a Stewardship Division, Transportation Ministry, Hospitality Ministry, Audio Visual, Public Relations Ministry, Publication Ministry, Praise & Worship Team, Praise Dance Ministry, Drama club, and St. Mark 4(B) Baptist Minstrels and various Leadership Conferences and Workshops.

St. Mark 4(B) has grown from 65 members to well over 400. This visionary heeded the voice of God, as he prepared St. Mark 4(B) to fulfill the vision of a new church! With much prayer and dedication, Pastor Simmons brought vision to reality through groundbreaking services April 1999. St. Mark 4(B) Missionary Baptist church experienced the move of God as they walked from the "old" church and into the "new" January 2000. His leadership abilities continue to shine as the church body continuously moves to higher heights and deeper depths in reaching the lives of those in and around the community. Reverend Simmons, a humble servant of the Lord, preaches, teaches and exemplifies his established theme: "Preparing God's People to Walk in Destiny". It is his desire that no one who enters the sanctuary will leave the same way that they came, but that a word will be spoken, a prayer will prayed, or a song will be sung, that will draw them closer to our Lord and Savior Jesus Christ.

Much of our history has not been documented; nevertheless the visionaries that God have placed to build up this segment of the body of Christ have always identified the move of God! Through divine vision and spiritual leadership, this church body has moved from "church as usual" to Kingdom Missions. History is being made as we move forward in response to the vision that God has given to our Leader.
