The Reverend Dr. Kenneth Baily

Senior Pastor

Called to NHCC in the spring of 2002. He grew up in Pennsylvania and Maine, attended college at Vassar, divinity school at Yale, and completed his master’s in public administration at Harvard.

In May of 2006 he was awarded his Doctor of Ministry by Hartford Seminary; his dissertation focuses on types of congregational leadership. Early part-time work as a carpenter and lobsterman has influenced the way that he has served churches in Maine (Yarmouth), Massachusetts (South Hadley), and Connecticut (West Hartford).

Earlier, he served as a legislative aide, speechwriter, and lobbyist in Maine. Baily’s post-graduate work has focused on counseling, healing, and in particular on conflict resolution. He was awarded the Mersick Prize for excellence in preaching by Yale University.

He has traveled (and especially eaten!) on several continents and holds particular commitments to mission, stewardship, Bible study, and youth activities.
