Paul will always welcome a bag of Herr’s Honey BBQ potato chips and a cup of coffee from Wawa. He grew up in Oxford, PA, so he considers himself a “local” (although Mike Sigman questions this designation).

In 2003, God changed the course of Paul’s life when Jesus became his personal Lord and Savior. From that time onward, Paul has always wanted to preach, teach and disciple others in the Word of God. He studied at Cairn University (B.S.) and Moody Theological Seminary (M.Div). While in college, Paul met his wife, Jen, who played softball for Ryder University.

David is married to his college sweetheart, Jessica, and they have boy-girl twins named Laina and Owen. They were married in 2006, and have grown to consider Lancaster County their hometown.

Graduating from Lancaster Bible College in 2011, David studied Worship Arts with an emphasis in Guitar as his primary instrument. His course load was shared equally between classes training him in Biblical Theology and Music Theory & Arts. His passion within the Music & Arts ministry is first people and their relationship with God, and second to present opportunities for people to connect with the Holy Spirit through the unique artistic personality that each person has.

In his free time, David loves to be outdoors camping, hiking, and fishing. He also loves to build things and exercise.

Steve Brubaker is the Counseling Pastor at GCC. He was born in Lancaster but as the son of a Navy retiree moved around a lot as a child before returning to Lancaster upon his Dad’s retirement.

Mike Sigman joined the Grace Community Church leadership team in July 2011, when he was appointed Lead Pastor. In this role, he serves as Grace’s primary preacher, while developing strategic vision and leadership in consultation with the Ministry Council. He is also responsible for the expansion of GCC’s local church partnerships and global outreach, and pastoral team development.

The two things Mike really loves about being pastor is spending time with people and preaching God’s Word. His desire is to challenge seekers to become followers of Christ, and to challenge followers of Christ to deepen their relationship with Christ.

His hometown is nearby New Danville, and his home church is Bethel Evangelical Congregational Church in Conestoga, where he began his relationship with Jesus Christ and answered God’s call to ministry. In ministry since 1986, Mike has been a church planter, pastor, denominational overseer for the US and global Evangelical Congregational Church, and seminary president at Evangelical Seminary, Myerstown.

A frequent preacher at area churches and camp meetings, Pastor Mike also served on the boards of Rawlinsville Camp Meeting and Water Street Mission.
