Lyman Coleman is one of the pioneers of the small group movement. He is a graduate of Baylor University, where he first became involved in small group ministry through the Navigators and Young Life. At New York University, he wrote his first program for small groups, Growth by Groups, which combines the spiritual disciples of the Navigators with the group accountability of Alcoholics Anonymous. Since the 1960s, Lyman has produced many training courses that have trained over 500,000 people in seminars held throughout North America. Lyman is the general editor of the Serendipity New Testament, the Serendipity Bible for Group and Personal Study, and the Serendipity Student Bible.
