Jon longs to see fund raisers, donors, and all the systems associated with stewardship increasingly reflect the lavish generosity of Our Father. This calling began while working with InterVarsity Christian Fellowship. He helped launch the National Advancement Officer program that resulted in 2 successful capital campaigns, the second of which went 40% over goal. Over the course of 14 years of helping InterVarsity improve and expand fund raising systems, he was involved in strategic planning, prospect research and prioritization, case development, feasibility studies, major donor engagement, foundation engagement, special events, midlevel donor engagement, coaching leaders in major donor engagement, training staff in personal support raising and developing theological foundations for fund raising.
When not involved in fund development, Jon enjoys time in nature, playing golf or tennis, eating or just having a good conversation. He also treasures time with his wife and two children.
