Continuing our focus on seasoned “leaders of leaders,” Asbury Theological Seminary is excited to add a Doctor of Ministry degree in Organizational Leadership in 2018. Students will dive deeply into adaptive leadership to become culture shapers in their ministry contexts. Collaborative (not solo) leadership requires particular character, strategy, and perspective. Anchored in biblical and theological foundations, supported by relevant leadership theory and practice, the Organizational Leadership D.Min degree equips pastors, directors, and educators. Students’ capacities develop from the inside out in a vibrant, spiritually formative environment that equips minds, hearts, and hands for a new season of calling.

Dr. Bryan Sims has worked since 2001 as a Leadership and Organizational Change Coach with Spiritual Leadership, Inc. (SLI) where he has trained and coached leaders, teams, churches, and organizations over extended periods of time to bring spiritual awakening and missional effectiveness. In his work with SLI, he has worked in several United Methodist Conferences including Northwest Texas, West Virginia, Tennessee, Kentucky, Nebraska, and Alabama-West Florida. In each of these places significant transformation is occurring in leaders, churches, and communities, as well as in the conferences. Bryan has also led groups of business leaders through WorkLife Incubators in which leaders are growing in Christ and learning new ways to integrate their faith and work. His most rewarding work has come through coaching three dying congregations in West Virginia to become a united, new community of faith (SLI ReStart). This new church has discovered the power of team leadership in covenant, lay mobilization, and intentionally effective disciple making and mission.
In addition, Bryan is a co-author on version 2 & 3 of the L3 Leadership Incubator Materials developed in partnership with Discipleship Resourcesand SLI (2008, 2010), along with two audio CD’s: Demonstrate Your Power (1999) and Black and White (1997).
