About Global Impact Services

Insights and information for your mission to the nations.

Who are we?

We are passionate about the Great Commission. After fifteen years in cross-cultural ministry here and abroad, Mark saw the unmet needs of the world and the untapped potential of the local church. In 2007, he launched Global Impact Services (GIS) to equip the church and her agencies for greater impact. Since then, we have consulted with scores of ministries and debriefed hundreds of missionaries. Mark has led mobilization conferences, written missions curriculum, served on the staff of Perspectives in curriculum development, taught in colleges and seminaries, and spearheaded the opening of a refugee welcome center.

What do we do?

GIS offers a range of Consultation, Mobilization and Preparation services, which are detailed in the links below. Currently, our primary focus is on mobilization of the local church through the Journey to the Nations study, which is now available to host classes across the US. (A self-study option will debut by Summer 2023.) All other services continue.

What is “Journey to the Nations”?

Journey to the Nations is a division of Global Impact. This six-session study explores the foundation of God’s global mission and our part in it. It is the most effective mobilization resource we offer. For more details and to take or lead a class, click the button below.
