Mark Grisham owns and operates a construction equipment company. He lives in Nesbit, Mississippi, with his wife Kellye, and teenage daughters, Erica & Melissa. Mark has lived in Desoto County since 1967, and is proud to call Mississippi home.

He went to college at Ole Miss and at Arkansas State University, where he played football and majored in history. At ASU his passion for Civil War history caught fire, and he began reading voraciously about the subject.

Mark has two older brothers, John & Ken, and two sisters, Beth & Wendy. His parents are retired and live in Northern Arkansas in the Ozark Mountains.

Mark works closely with Impact Missions to assist David and his staff in their efforts to raise funds for the ministry. He hopes their books will generate enough revenue to build a campus for these troubled kids.
