Greg Johnson

Interim Pastor

Growing up in Ethiopia as the son of missionary parents, Greg developed his commitment to Christ, his passion for the church, and his heart for people that have propelled him through a lifetime of Christian ministry.

Greg and his wife, Becky, raised their two daughters, planted churches, developed leaders, and led community development and famine-relief projects among the Maasai tribe of Kenya (1978-1997). As Director of Marketplace Ministries for CMFI (1997-2002), Greg developed partnerships, strategies, and teams to get Christian workers into places not open to traditional mission methods.

From 2002–2017, Greg served as Lead Pastor of Generations Christian Church in Trinity Florida. Just like in his missions career, Greg continued to connect people to Christ through multi-site worship services, community transformation, and global outreach.

Greg is a relational and visionary leader – always caring about people and always seeking to advance the kingdom of Christ – across the street and around the globe!
