David & Terri Sumlin

Marriage Retreat Speakers


Meet the Sumlins


David and Terri Sumlin are co-founders of Marriage Life Ministries and authors of the Marriage Innovators Workshop®, Intimacy of Marriage® and Oneness of Marriage® series – all designed to help couples enrich their marriages through the application of biblical principles and adventure-based learning. For more than 15 years, they have served as international marriage educators, retreat leaders, pastoral counselors and conference speakers.


The Sumlins’ unique approach to marital education is built upon some of the advances found in neuroscience, psychology, physiology and adventure-based therapy, which ultimately is tested through the lens of God’s word for validation. The result is an activity-based marital enrichment process that helps couples derive behavioral transformation and sustained learning. (Studies show that couples who participate in these types of marital enrichment programs are 84% more likely to report having increased levels of marital satisfaction long after the program has ended.)

David earned his master’s degree in biblical counseling and doctorate in marriage and family ministry from Dallas Theological Seminary. Upon graduating, he served as a pastor at a church in Northwest Houston for seven years before serving as a full-time marriage educator. Terri earned her bachelor’s degree in education from the University of North Texas, which she used to serve more than 20 years as an English teacher. She is now a leader in women’s ministry and serves full-time alongside David in their marriage and family ministry.
