Leadership Team


David’s Tent is an independent body comprised of Christians from across many different denominations and church expressions. Our events are organised and run by a small staff team working alongside an army of volunteers (team builders) to make it all happen. The Trustees and the volunteer Core Team help oversee the practical, spiritual and pastoral aspects of everything we do. 

Tiffany has been involved with leading David’s Tent since it’s inception. She lives to see this generation become stronger in prayer, creativity, discipleship, prophetic lifestyles and worship. She is passionate about seeing communities centered on practicing the Presence of God and releasing an offering of worship and prayer to change the atmosphere of a region, city and individual lives.

Rolf’s passion is pursuing the heart of God. In 1999 whilst doing his masters degree in Divinity, he had a vision where he saw a glimpse of “the rebuilding of David’s fallen tent”. He saw people of every tribe, tongue and nation adoring Jesus. It was a life defining moment, setting him on a course of passionate worship and a heart for missions. Rolf and his wife Nicole moved to the UK in 2005 where they started Paramount Medical Solutions, a medical device company that develops and markets urology products to hospitals. They now live in Tunbridge Wells with their 4 children.
