Our leaders consider it a privilege and blessing to be used by God to serve the global church through the ministry of Langham Partnership. Read more about these godly men and women with a heart to bring God’s Word to God’s people around the world.

John Libby, National Director, Langham Partnership UKI

John joined the Langham Leadership Team in May 2016 as Executive Director for the UK and Ireland.

John is an ordained minister in the Church of England and comes to Langham after many years in Parish Ministry.

His job is to raise the profile, funding and administration, giving maximum support to our three international ministry streams. A place on the international executive team helps define strategy such that those three streams deliver maximum positive global impact. John spent 16 years in international banking with significant experience in senior financial management in the UK and USA. Ordained in the Church of England, he spent 18 years as vicar of St. James, Carlisle. As a Christian entrepreneur John built and fund-raised for charitable enterprises including the Kepplewray Trust, with connections in Africa.

He and the wider family are involved in local church life and love to lead small groups and participate in marriage ministry whenever possible.

He and Angie spent 15 years in India as Crosslinks mission partners before returning to the UK.

From 2009-2015, David was Director of Open Learning at Trinity College Bristol out of which the GOLD Project has formed. Since he was sixteen, David has been riding motorbikes and is actively involved in the Christian Motorcyclists’ Association. He and Angie are actively involved their local church in Bristol.

Dr Desta Heliso: Desta was born to a Christian family in rural Ethiopia. He is married to Joanna Jeffery and they have six children, three of whom are biological (Sophia, Ezra and Charis), and three adopted (Melkamu, Mekdes and Keab).  Desta received a diploma in theology in Ethiopia and then taught at a theological school, where he also served as Director and co-ordinator of ministries for over 300 congregations in his home area. He came to Britain and completed his PhD after which he returned to Ethiopia and joined the faculty of the Ethiopian Graduate School of Theology (EGST) as lecturer. After serving as Acting Dean of Studies, he was appointed Director in 2008, a position he held until the end of 2015.  Desta has now left EGST after 16 years of service. He and his family have moved back to the UK for family reasons. Desta continues to lecture part-time at theological institutions and work on academic research projects as well as running a new not for profit organisation called SOPHOS AFRICA.

This variety of experience across different countries, cultures, sectors and business sizes also helps him to bring fresh perspectives that he can share with the organisations that he works with. He is currently CEO of Beacon, a challenger SaaS platform looking to change the landscape of online advertising by driving transparency, increasing data accuracy and reducing fraud. Nigel also holds a number of business interests including non-executive directorships, board advisory positions and charity trusteeships.

Judith Sawers: Judith and her husband, Will, work with Wycliffe Bible Translators supporting national translation teams in central Africa, and as part of Wycliffe’s member care team in the UK.  Judith’s degree in Biblical Studies and Linguistics and a call whilst in her teens to serve God cross-culturally led them in this direction. Her work now focuses on publicity and prayer-raising for the Central African Republic through networking and social media, and supporting colleagues in raising personal financial support in the UK.  Her experi ence of the gaps in training and resourcing of the church in central Africa has made her very much aware of the potential for Langham’s ministry there, as in so many other challenging situations around the world. The combination of both a new generation of Bible teachers and mother-tongue Scriptures seems one of the most powerful tools for the development of mature churches worldwide! Having recently moved to west Devon, she is enjoying building relationships in the community there and seeking God’s place in the local Christian family.

She has also had the opportunity to visit mission work, often involving theological colleges, in Ecuador, Ghana, Nigeria and Niger. Her involvement on the councils of Bible Society, Global Connections, EA, Latin Link and SIM (not all at the same time!) has also been fairly extensive. She taught Old Testament Studies for three years at the Ethiopian Graduate School of Theology in Addis Ababa. Mary has authored several books including the BST commentary on 1 and 2 Samuel and the Tyndale Commentary on Judges.

Nigel Bridges: Nigel has over 30 years leadership experience in the consulting and technology sector.  His career has included significant UK and international experience in managerial and executive roles including Divisional Director, Managing Director, COO and CEO for larger corporates and smaller SME’s.  After graduating from City University (now Cass) Business School Nigel started his career in management consulting and business development in the UK and Hong Kong; before moving into general line management.  His corporate career saw him managing ever larger business unit across the UK and Europe including a number of turn-arounds.
