  • We attach utmost importance to TEAM-Work. The TEAM of DCTB, is a workgroup or crew that is an institution in itself. Our work depends on the support of friends, not only financially but also in respect of practical and spiritual strengthening. At regular TEAM-conventions the TEAM discusses and thinks about the latest questions regarding career, family and Christian community in general. Therefore it is necessary to listen at God’s word and talk about it together. The TEAM provides the required platform for both aspects. The goal is to share the outcomes of the TEAM- conventions at camps, other conventions and conferences. Our motto is not: „great somebody else is doing it“, but rather „it’s good to have each other!“
