Dr. Curtis Sergeant served with the International Mission Board (IMB) as a pioneer church-planting missionary among an unreached people group in China. When the work began to produce rapidly multiplying churches and he was no longer needed there, Curtis transitioned to a
ministry of training others to do the same sort of ministry. In that role, he intensively trained hundreds of people from a wide range of nations, denominations, and agencies, who have collectively catalyzed movements that have planted millions of house churches.

A few years later, Curtis began to interface with the major house-church networks of China as a trainer and consultant. Later, he served as the IMB's vice president for global strategy, where he oversaw the research department while continuing to fulfill a training role as well. From there, Curtis went to Saddleback Church as the director of church planting. While at Saddleback, he helped to develop an online training system for missions and led some extremely large-scale church-planting projects, especially in India. During that period, he was also instrumental
in initiating church-planting ministry among nearly a hundred previously unengaged people groups. Curtis then served as international vice president of e3 Partners for three years.

Curtis currently operates MetaCamp, a disciple-making and missions training center located in Dadeville, Alabama. He also works in leadership with Zúme and 24:14. Curtis and his wife, Debie, have two grown and married children, Nathan and Megan.
