Mark Sappington

Associate Director

Mark Sappington grew up in Peculiar, MO. He is the son of Scott and Mary Sappington and the second of six children. Mark attended Rockhurst University, studied economics, and following his junior year was drafted by the Los Angeles Angels as a Right-Handed Pitcher in 2012. He pitched in the minor leagues for the Angels for two years before being traded to the Tampa Bay Rays. That trade proved to be the pivotal moment of Mark’s life as it led to his reversion back to the Catholic Faith. Mark started attending daily Mass, gave up all his social media, stopped pursuing sinful relationships with women, and fell in love with Jesus in a radical way. His heart has been in the process of continual conversion since that Lent. A “practicing” Catholic since February 2015, Mark’s unique fire for the faith has been driven by his experience of forgiveness and redemption through the sacrament of reconciliation. He wants others to be who God created them to be!

Mark lives in the Westport area with three other Catholic men who are going after the heart of Jesus in the heart of Westport; he is also engaged to Lilly, a lovely woman who matches his fire for Christ. Mark shares a unique understanding of the discernment process via his brother, Paul who is in seminary. Mark’s favorite Saints are St. JoseMarià Escriva and St. Catherine of Siena. He enjoys going to Waffle House with his brothers, shooting off fireworks, learning about people’s strengths, roadtrips and spreading the Gospel. Mark is deeply passionate about human formation and the building of a virtuous life.
