Research and Writing
In his early years, Bird served on Carl George’s senior management team of the Pasadena-based Charles E. Fuller Institute of Evangelism and Church Growth where he visited, interviewed, researched, and profiled many of the largest, fastest-growing, or newest churches in North America. In subsequent years, he did similar research and development for the Canada-based Leadership Centre Willow Creek Canada, and for the Asbury Theological Seminary-based Beeson Institute for Advanced Church Leadership (1996-2006). From 2006 to 2018 Bird served as Director of Research and Intellectual Capital Development at Leadership Network.
