Jon pastored in a “mega-church” in Williamsburg, Virginia, for 10 years before moving to Brussels, Belgium, to help plant “micro churches” as part of Communitas’ project, The Well. In 2015, Jon returned to the States to apply the lessons he learned about adapting the church to post-Christendom as Lead Pastor of Ecclesia Hollywood. In 2020, Jon authored Positively Irritating: Embracing a Post-Christian World to Form a More Faithful and Innovative Church to equip fellow church leaders on their similar journeys.

Today, Jon serves as Communitas’ Chief Strategy Officer in addition to coaching Pastors and Planters nationwide and Training denominations in Missional Ecclesiology and Church Planting. Jon and Kristyn celebrated 22 years of marriage in 2024 alongside their children, Addy (19) and Jax (16). Jon graduated from The College of William and Mary in Virginia (B.S. 1997) and Trinity International University (M.Div. 2002). The Ritner’s favorite mission fields in town are Children’s Hospital LA, where Kristyn volunteers, their local schools, parks, and gyms, and their favorite local pub, Over/Under Public House.
