Gregory Mack, Sr.



Pastor Gregory Mack, Sr. is a third generation preacher of the gospel, with a strong background in congregational care and a rich family heritage steeped in the word of God and operating in the gifts of the Spirit. Born in Oakland, Ca, he received his early spiritual training at the Little Temple Church of God In Christ under the tutelage of his pastor and father the late Reverend Robert D. Mack Sr., and mother Michelle R. Mack. He received and confessed the Lord Jesus Christ as his personal savior in accordance to Romans 10:8-10, and was baptized in August of 1993.

Never one to shy away from a challenge, at the age of 14 Pastor Mack felt the calling of the Lord to begin ministering to the people of God through music and began taking lessons to play the organ and became one of the main musicians at his father’s church. During that time, Pastor Gregory Mack Sr., also realizing his love for ministry also began serving in multiple offices within the church often accompanying his father while he ministered to the church body inside and outside of the church. After a massive stroke left Pastor Robert Mack unable to continue his full pastoral duties, Pastor Gregory Mack Sr. began to take on the responsibility of church leadership in regards to preaching and teaching the Word of God in his father’s stead. In June of the year 2000, Pastor Gregory Mack received his license to preach and was ordained as an Elder in the Church of God In Christ, Inc. in 2003.
