Leadership within the Order of Mission (TOM) is structured through the elected Senior Leader supported by a regionally appointed Leadership with a selected Chair in each region.


The role of the Leadership is to carry, guard and develop the spiritual vision and charism of the Order; leading by example of life as well as words, and watching over the Order to ensure it conforms to the teaching of the Christian church, encouraging the members towards a reflective dependence on the Bible and the leading of the Holy Spirit.

Keld Dahlmann is the current Senior Leader of TOM. He is based in Aarhus, Denmark where he serves as the International Pastor at Aarhus Valgmenighed having transitioned from his previous position of Senior Pastor. In that role he grew the church to one of the largest in Scandinavia and launched the ecumenical church planting network KPN. Keld has served as a teacher, mentor and consultant in a broad variety of contexts and communities across Europe, the USA and Africa. Keld holds a B.A. and an M.A. in Theology from the University of Aarhus and studied missiology at Fuller Theological Seminary in Pasadena, California.


Alongside his wife Sara and their four children Keld has integrated the extended family way of life over many years. They originally got connected to the ministry of St. Thomas Church, Sheffield in the late 1990's and over the years a web of relationships and events emerged that connected many people from the UK and Denmark with TOM as a place to grow and extend longtime relationships and partnerships in discipleship and mission. Having served as Chair of Guardians for the Scandinavian region for a number of years Keld was elected as Senior Guardian in 2015.

Accountability to the wider church is maintained through Visitors. We believe that in this way we can avoid cumbersome hierarchical structures that hinder the dynamic apostolic move of the Kingdom, while at the same time maintaining a transparency of leadership throughout and to those from whom we derive our spiritual heritage.
