John worked for Gronning Engineering Company (1986-1990) as a water resources/water rights engineer in his early career. Then in 1990, he moved with his family to serve as a missionary engineer with the Baptist General Conference (now called Converge) in two African countries. They first served in Ethiopia (1990-91) designing and constructing a large gravity flow for a rural town and engaged in evangelism alongside the local church. Because of civil war, they had to leave Ethiopia pre-maturely but soon found themselves back in Africa focused on reaching the Fulani in Cameroon (1993-2006). The Dallmanns were involved in over 50 community water projects, church planting efforts and the establishment of a local hospital in the town of Banyo. John then served with Samaritan's Purse first as their Senior Water and Sanitation Advisor (2008-2010) and then as the Country Director for Niger (2010-2012).
John's call to ministry came in 1984 after serving with CRU in Kenya, East Africa. The call was to "use engineering to win people for Christ that would not be won otherwise." That has been his 'true north' ever since . . . attempting to combine both the spiritual and physical and live the gospel in word and deed.
John has been married to Gala since 1986 and really enjoys traveling and doing ministry together with her. They have five children who are now scattered around the global.
