Dr. Mels Carbonell was the first to combine Spiritual Gifts with the 4 DISC Personality Types. His Uniquely You Combination Spiritual Gifts and Personalities Profile is one of, if not the most popular faith-based assessment available today. He presented his Combination Spiritual Gifts and DISC Personality Profile at Saddleback Church with Pastor Rick Warren. Saddleback and Rick Warren have popularized the SHAPE Model for ministry. Many ministries and organizations now use personality profiles to improve team building, new member assimilation, networking, leadership, conflict resolution, relationships, teens, parenting styles, communication styles, and ministry involvement.
