Dr. David Vaughan


David grew up in the St. Louis area and came to know the Lord in 1975. Throughout the 1980s he ran a youth ministry called Moriah which was usually a packed house of youth eagerly wanting to study the Word each week. He and his wife, Diane, married in 1989. Around that time his church commissioned him to be part of a church plant in St. Peters, Missouri which he agreed to. In 1996 Liberty called David to be its pastor where he has faithfully preached and shepherded since that time.

David serves in a variety of areas including Director of Liberty Leadership Institute, Research Professor and Lecturer at Whitefield Theological Seminary, and President of Liberty Classical Center. He also appears weekly on the KSIV Encounter program where he interviews authors on their books encompassing a variety of theological topics.

In addition to these ongoing activities, David also addresses current and biblical issues through writing.  His articles have appeared in numerous national publications.  He has also authored several books: Give Me Liberty: The Uncompromising Statesmanship of Patrick Henry; The Pillars of Leadership; Jonathan Edwards; Extra Muros; Statesman and Saint: The Principled Politics of William Wilberforce; The Beauty of Modesty and A Divine Light: The Spiritual Leadership of Jonathan Edwards.

Diane has served in a variety of areas at Liberty over the years including teaching at Liberty Classical Center, running the Ladies’ Ministry, leading the interior design ministry, and teaching ladies’ Bible studies. Diane currently serves as the head nurse for Thrive, which is a large pro-life ministry that gives medical services to pregnant women.
