Our International Team

International Consultants (IC’s) are vital to our ministry! They come alongside the leaders in their regions through one-on-one visits, addressing challenges and seeking solutions. They provide needed support, praying with them and serving as a sounding board. Whether they are encouraging a leader whose institution is facing financial problems, facilitating at an Institute for Excellence or local workshop to better equip faculty or providing training for seminary leaders, these men and women work tirelessly to see transformational theological education, the kind that produces leaders who make a difference.

IC’s are experienced in training Christian men and women of vision, integrity and competence. Most IC’s have served in multiple capacities of leadership in seminaries, schools and other institutions, and are in some way products of one of our partner schools.
