Our UK board of trustees

The UK operation of Serving In Mission is governed by a Board of Trustees. They are driven by the desire to take the gospel of Jesus Christ to those who do not yet know it and have a wealth of mission experience.

The Rev'd Jonny Dyer (co-chair)

Before taking up his role as Associate Rector at All Souls, Langham Place Jonny studied Theology at Reformed Theological Seminary in the US. Prior to that he worked as a solicitor for 11 years. He is married to Naomi and they have two sons, Tom and Ted. His interests include following England in sport and suffering for it, beating his students at table tennis and hanging out with his family. He also enjoys walking, good food and good conversation.


Mark Heasman (co-chair)

Mark is Chief Executive Officer of Christian Camping International. He has previously been CEO of Ormiston Families, a charity which works with vulnerable families in the east of England; and CEO of Rock UK, a Christian youth charity. Mark is married to Claire and has five children. They live near Manningtree on the Suffolk-Essex border.

Anthony Harris

Following a doctorate in radio astronomy I worked for BT, eventually specialising in the design of data networks. I’ve lived with my family in St Albans for nearly thirty years. We have three children, and seven young grandchildren. Chris and I belong to a local church, where we’ve both been Churchwardens, and I managed site and building issues after taking early retirement. I had been chair of MECO trustees for many years, and was delighted at the merger of MECO and SIM in 2016. I enjoy using my hands, at church as well as home. And sailing my dinghy, but only in the summer!

Yoseph is from Ethiopia but now lives and works in the UK. He and his wife Mekdes have a 17-year-old son, Nathan. Yoseph has taught at higher education institutes in Ethipioa and the UK and has extensive ministry experience at local and national church level. He serves as a deacon at Pinner Baptist Church, London, where he also preaches and teaches regularly. He describes himself as an unrepentant Chelsea fan.
