Who We Are

A Network of Churches

Synergy Missions Solutions Network (Synergy Missions) is a network of unified and cooperating churches that are in cross cultural, church-to-church partnerships. 

Missions Solutions

Synergy Missions exists to provide missions solutions for evangelical churches for the purpose of spiritual impact and life transformation for individuals, churches, communities, and nations.

Serves Churches, Empowers Partnerships

Synergy Missions' leadership serves the network churches through consulting, training, developing church-to-church partnerships, and implementing effective missions solutions. 

Church-to-Church Partnerships

Church-to-church partnerships are the foundation for Synergy Missions because it is a Biblical way that God grows His kingdom.  This is our philosophy of partnership:

The goal of a partnership is for two churches from distinct cultures to work alongside one another in meaningful and culturally relevant ways. The partnership is under the direction and empowerment of God for the expansion of His Kingdom in both contexts.
