Dr. Horstmann, who grew up in Bennington, Vermont, spent fourteen years as the Senior Pastor at Immanuel Congregational Church, United Church of Christ, in Hartford, prior to coming to Round Hill Community Church. Before that, he spent twelve years as the Pastor at First Congregational Church in Hopkinton, New Hampshire. His education includes an S.T.M. and M.Div. from Union Theological Seminary, D.Min. from Andover Newton Theological School, and B.A. from Union College. He currently serves on the boards of Hartford Seminary, where he also has been an adjunct professor, and the South Marshall Interfaith Coalition in Hartford.

He has said that the practice of ministry is always about pointing the way for a local congregation to become fascinated by the promise Jesus made to his disciples that “greater things than I have done shall you do.” He believes that preaching and worship that engage the imagination, the heart, and the mind fuel this fascination.

At the same time, he thinks that as we endeavor to live with faith, hope, and love we should laugh and take ourselves lightly, be kind to one another, pause for prayer when our lives have run off track, and savor the beauty of creation

Of his life work, Dr. Horstmann says, “I love the ministry. I love the opportunity to think and dream and plan and act with people of faith toward a vision of enhancing life locally and globally.”
