our people

We serve in our local churches, as elders, youth workers, worship leaders and council members. We see no divide between what happens on a Sunday and the working week that follows.

We are accountants and lawyers, trainers and administrators. We work together to bring the best of our expertise to the Church, to cheer our fellow Christians on as they put faith into action around the world.
