The Queen has given her approval to her nomination to replace Rt Revd Ian Brackley who resigned in September.
The Revd Canon Dr Jo Bailey Wells was educated at Corpus Christi College, Cambridge and then at University of Minnesota, USA, she later trained for ordained ministry at St John's College in Durham.
Jo Wells said: "I am both honoured and humbled at the prospect of living and serving in the diocese of Guildford as the next Bishop of Dorking.
"I am excited to get to know the area and its people: to discover what God is up to and to share God's abundant blessings within and beyond the church.
"I've always found immense joy in nurturing disciples and teaching the faith. I shall look forward to opportunities for this around the diocese - particularly with young people through its many thriving schools and colleges - that each may discover the fulfilment and joy which Jesus offers to everyone. At the same time I expect to learn a lot - as well as laugh a lot - through this new opportunity for serving together."
Jo Wells was Chaplain of Clare College, Cambridge from 1995 to 1998 and Dean from 1998 to 2001, she's also served as a lecturer.
Congratulations Jo Wells, new Bishop of Dorking; will leave a huge gap; I pray for her and family, and celebrate for Guildford Diocese.
