Pastor David Grissom is the esteemed Senior Pastor of Mt. Calvary of the Pentecostal Faith Church, a devoted leader with a heart for ministry and a passion for souls. He has embraced pastorship with faith, devotion, and commitment to guiding others toward transformation through the Word of God.

Pastor Grissom was called to preach the Word of God on March 10, 1981, answering a divine call that shaped his life and ministry. Through years of prayer, preparation and service, he grew under the tutelage of the late Pastor Janie M. Wilson, whose wisdom and mentorship played a pivotal role in his development as a spiritual leader. On June 27, 2010, Pastor Grissom was officially installed as pastor of Mt. Calvary, stepping into his role with humility, strength, and a deep desire to shepherd God’s people.

Beyond his role as a pastor, family is most important in his life. He is happily married to Lady-Elect Melissa Grissom. Together, they have been blessed with three daughters, one son-in-law, and a cherished granddaughter—a family rooted in love, faith, and a shared commitment to God's kingdom.

Pastor Grissom carries a burden for souls, longing to see all come to Christ. His ministry is centered on holistic transformation, seeking to impact not just the spiritual well-being of individuals, but also their natural, physical, mental, and emotional health. His vision extends beyond the pulpit—his prayer is that every person he encounters experiences the fullness of God's healing, restoration, and purpose.

With a servant’s heart and a shepherd’s devotion, Pastor Grissom continues to lead Mt. Calvary with faith, integrity, and an unrelenting pursuit of God's will. Through his preaching, leadership, and unwavering dedication, he strives to build a ministry where lives are changed, hearts are renewed, and souls are brought into the light of Christ’s love.
