About Tim Witmer

Dr. Timothy Zimmerman Witmer grew up in New Holland, Pennsylvania where he was raised in a Christian home. He attended West Chester University where he became a Christian through the ministry of Campus Crusade for Christ. After graduating with a Master of Arts in Philosophy (1975) he attended Westminster Theological Seminary (Philadelphia) where he completed the Master of Divinity degree. On November 11, 1979 he was ordained as a Teaching Elder in the Presbyterian Church in America and was installed as Assistant Pastor of Berith (now Springton Lake) Presbyterian Church in Newtown Square, Pennsylvania. He was called to serve as Pastor of Crossroads Community Church in Upper Darby, Pennsylvania and was installed on December 14, 1986. He was designated Pastor Emeritus in January, 2015. He now serves as Pastor of St. Stephen Reformed Church in New Holland, PA

While at Crossroads he began his doctoral studies at Reformed Theological Seminary (Orlando). His dissertation led him to the subject of shepherding as it related to the work of the elder in preventing member inactivity. His advisor was Dr. Steve Childers. He received his Doctor of Ministry degree in 1998. He began to lead “Shepherd Our Sheep” (SOS) workshops and seminars to aid church leaders understand the importance of shepherding their congregations.

In 1999 he was invited to join the faculty of Westminster Theological Seminary where he is Professor of Practical Theology, Coordinator of the Department of Practical Theology, Director of the Mentored Ministry Program, and Director of the Master of Divinity degree program.

In addition to his work at Westminster Seminary he also serves as Pastor of St. Stephen Reformed Church in New Holland, PA which is making a transition from the UCC  to the PCA.

He married Barbara, his high school sweetheart, on July 26, 1975. They have three children: Sara, Rebecca, and Nathan. The Witmers have seven grandchildren: Mikayla, Abigail, Kathryn, Emma, Lily, Benjamin, and James.

Tim has played tuba in several professional musical ensembles and has performed with the Westminster Brass since 1976.

He was motivated to write The Shepherd Leader as he became aware of increasing numbers of congregations who were like sheep without a shepherd. His objective is to see all church leaders embrace their calling to shepherd the flock.
