Doug Graber Neufeld, Director

Doug joined ACC as Director in August, 2017, after spending 2 years as Livelihoods advisor for Mennonite Central Committee in Kenya.  Doug worked with rural farmers, and with urban informal settlements, on water and agricultural issues, and saw firsthand the impact of climate change in East Africa.  Doug is Professor of Biology at EMU, helps to direct the Environmental Sustainability program, teaches water and pollution related courses at EMU, and works with rural agricultural communities of Appalachia on water issues.  He earned his Ph.D. from the University of Texas, Austin and held postdoctoral fellowships at  the University of Arizona and the University of Otago, New Zealand.  In addition to 2 years in Kenya, he served two years with Mennonite Central Committee in Cambodia working with Royal University of Agriculture and the Royal University of Phnom Penh.  In his free time, he likes to explore the local mountains with his sons and wife, and work in his garden.

Joseph is a writer and musician with a life-long passion for environmental work. A 2020 graduate from EMU, Joseph devoted significant energy during his time there to studying the environment through both independent and curricular learning, incorporating a semester at the Oregon Extension and a cross-cultural program in India into his education.  Joseph started his time at ACC as a Climate Futures Fellow, conducting research on the ethical implications of environmental expressions in U.S. Mennonite hymnody. He has since transitioned into the Program Assistant position, and is excited to further his work with them.

Doug Kaufman, Director of Pastoral Ecology

Doug Kaufman smiles at the camera in front of greenery; his short hair and beard are white and he wears rectangle glasses.

Doug is a pastor and environmental activist who began as the Director of Pastoral Ecology at ACC in February 2018. In this role he organizes and leads pastoral and leadership retreats on climate change, helping congregations reduce their carbon footprint and engage society more broadly in climate action. He continues as a pastor of Benton Mennonite Church, Goshen, IN, a Green Patchwork congregation with Mennonite Creation Care Network. Doug first became passionate about creation care when he discovered that the Elkhart River, where they often baptize, sometimes is compromised with too much manure. Since 2005, he has led a Hoosier Riverwatch group there. The congregation, whose vision includes “pursuing God’s peace at the river,” has also led river cleanups, installed solar panels, includes recycling, and has a green group. Doug recently completed a Th.M. in theology and ecology at the University of Toronto and has a M.Div. from Anabaptist Mennonite Biblical Seminary, Elkhart, IN. He is also trained as an Indiana Master Naturalist. He previously served as a conference minister with the Indiana-Michigan Mennonite Conference.
