Shannon Neill

Voting Member

Latino Teaching Team

Over the past 20 years of ministry in Latin America, IBAC has formed relationships with thousands of Latino pastors and leaders. In the course of our equipping ministry, IBAC leadership has identified several pastors who have the gift of teaching and leadership. For the past several years a significant ministry focus of IBAC has been to equip, develop, and mobilize these gifted men who have begun teaching and leading in our Bible Institutes. The strategic plan to mobilize these gifted, national leaders results in the expansion of our geographic coverage, puts these talented servants “in the game” of missions, and relieves the travel pressure from our current leadership.
