Since February 2003, Landmark Pentecostal Church has been blessed with the anointed ministry of Reverend Jason Calhoun. Before accepting the pastorate position, he served as a highly respected and favored evangelist for more than 10 years and has been privileged to speak at many regional and national meetings throughout the USA.  Pastor Calhoun's ministry has a threefold emphasis on exalting Jesus, edifying the church, and evangelizing our world.

Pastor Calhoun graduated from Faith Christian in Neosho, MO. He also attended Christian Life College in Stockton, California. He graduated with honors from Texarkana Community College with an Associate in Behavioral Science and Magna Cum Laude from Texas A&M-Texarkana with a Bachelor of Arts and Applied Science with a concentration in Organizational Leadership.  He obtained a Master of Science at Texas A&M - Texarkana in 2020 and achieved his Doctorate in Education from Baylor University in August 2023.

Pastor Calhoun’s wife, Dina, has been a shining light at Landmark. She can be found serving in several roles at Landmark and exemplifies the Church’s mission of being a true Christian. She has obtained an Associate of Arts with a Concentration in Fine Arts in 2019, and a Bachelor of Science from Texas A&M-Texarkana in 2021. 

Pastor and Sister Calhoun have three wonderful children, two sons and one daughter, a daughter- in-law, and enjoy spending their time with their five grandchildren.
