About Us
Dr. David and Terri Sumlin

The Sumlins are co-founders of Marriage Life Ministries and authors of the Intimacy of Marriage®Oneness of Marriage®, and Marriage Innovators Workshop® series designed to help couples enrich their marriages through the application of biblical principles and adventure-based learning. They both have served over the last 15 years as international marriage educators, retreat leaders, pastoral counselors, and conference speakers.

Our Passion & Unique Approach

Our passion for helping couples embrace God’s design for marriage stems from our personal encounter with God’s redemptive grace in restoring our own broken marriage. This passion falls under a much larger calling of proclaiming the truth, love, and worship of God through a personal and purposeful relationship with Jesus Christ. To this end, we founded Marriage Life Ministries in 2012 as a means of proclaiming the gospel through the vessel of marriage and family ministry.

Our unique approach to marital enrichment is built upon some of the advances found in neuroscience, psychology, physiology, and adventure-based therapy, which were then tested through the lens of God’s word for validation. The result is an Adventure-Based Marital Enrichment model that helps couples derive behavioral transformation and increased levels of sustained learning. While traditional therapeutic approaches can yield low to moderate success in terms of marital outcomes, couples who participate in our programs are 84% more likely to report having sustained levels of increased marital satisfaction long after the program has ended.
