Advisory Board

David Hill, Pastor
Abundant Grace Church, Brighton

Dave grew up in a small town in rural Pennsylvania. He attended Dartmouth College where he joined the Dartmouth Area Christian Fellowship, a transforming experience where he was filled with the Holy Spirit and guided by strong biblical teaching on what it meant to follow Jesus Christ wholeheartedly. He joined in the vision God gave the church to plant similar churches in college towns around New England. In 1981 Dave married Ingrid, and two weeks later they helped lead a church planting team in Amherst, Massachusetts. They have resided in Boston since 1989, where they hope to keep being a light for Jesus in the city and to see a book of Acts awakening in Boston. Abundant Grace Church is part of a network of churches called Newfrontiers, a global movement of church planting with a goal of spreading the Good News of the Gospel.

Stephen Witmer, Founder of "Small Town Summits" Ministry
Pastor / Author / Adjunct Professor

Like many young pastors, Stephen dreamed of pastoring a big, center-city church, believing that's where God does His most significant work. Instead, he became a pastor at Pepperell Christian Fellowship in Pepperell, MA, with a population under 12,000. His book, "A Big Gospel in Small Places: Why Ministry in Forgotten Communities Matters", was published in 2019. Here he explains his about-face, makes a theological case for small-place ministry, and challenges our un-Biblical definitions of significance and strategy. From this vision emerged the ministry, "Small Town Summits", which provides relevant and strategic resources for pastors and lay-ministers in small places. Stephen is also an adjunct professor of New Testament at Gordon Conwell Theological Seminary in South Hamilton, MA
