About Us

Multiplication Network Ministries (MNM) is a non-profit organization that equips leaders with the tools and resources to strengthen and multiply healthy churches. We do this through contextualized training, providing reproducible materials, even in the most remote places on the planet.

MNM provides two main ministry platforms under each area. More Churches is a one-year modular program for church planting where leaders are challenged to plant new churches through practical skills, biblical training, mentoring and follow-up. Stronger Churches is an ongoing process to strengthen the local church. It includes evaluative tools to help assess the church's health and vitality, leading to strategic planning to enter into a preferred future.
