Dennis G. Rainey is an American Christian author, speaker, and ministry leader best known as the cofounder of FamilyLife, a ministry of Cru. FamilyLife says he helped lead the organization from its start in 1976 through 2017, expanding its reach internationally and focusing on practical help for marriages and families.
With his wife, Barbara, he became widely known for teaching and writing about family relationships from a biblical perspective. FamilyLife and Cru describe him as a longtime host of FamilyLife Today and note that he has written or co-written numerous books on marriage, parenting, and Christian living.
Across his career, his work has centered on helping couples and parents build strong homes, and that focus has made him a familiar voice in evangelical family ministry. Public profiles from FamilyLife and Cru consistently present him as a key figure in shaping the organization’s message and outreach over several decades.
