Mark Clavier was born in Greenville, SC but grew up mainly in south Florida and Virginia. After earning an A.B. in History from The College of William & Mary and an M.T.S at The Divinity School, Duke University, he spent more than twelve years in Anglican parish ministry first in Maryland and then in North Carolina.

 In 2008, he moved to the UK where he earned a PhD from Durham University for his dissertation on the role of delight in Augustine of Hippo's theology. After briefly returning to full-time parish ministry in the idyllic countryside of north Oxfordshire, Mark served as the Acting Principal and Dean of Residential Training at St Michael's College, Llandaff and then as Vice-Principal and Charles Marriott Director of Pastoral Studies at St Stephen's House, Oxford.

 He is now Residentiary Canon of Brecon Cathedral in Wales where he also directs Convivium, an initiative that seeks to promote living well with God, nature, and local communities. He is regularly invited to give public talks and lead retreats in both the UK and USA. He is also regular contributor to BBC Radio Wales programmes such as Prayer for the Day and Weekend Word. He is the author of books on Augustine, delight, and the challenge of consumerism. His latest book A Pilgrimage of Paradoxes: A Backpacker’s Encounters with God and Nature is an extended theological reflection on what the Welsh landscape has taught him about the nature of belonging.

 He spends much of his free time walking in the beautiful Brecon Beacons with his wife, Sarah, and their two Spaniels, Cuthbert and Humphrey.
