What is Pulpit Supply?

We often get requests from congregations seeking ministers for pulpit supply, as well as requests from ministers wanting to do pulpit supply. Churches, the ministers listed below are available for pulpit supply. Please contact them directly.

Don Grant


Don is Professor of Sociology at the University of Colorado Boulder. There, he directs a program that equips students to innovate solutions to some of society’s most pressing problems. He also directs a program for students pursuing careers in the helping professions that addresses the opportunities for and challenges of providing care. In addition to teaching and conducting research on work, inequality, climate change, and the place of spirituality in secular settings, he is actively involved in the Industrial Areas Foundations, the nation’s largest and longest-standing network of local faith and community-based organizations.

He is interested in creating spaces for the “spiritual but not religious” to produce new forms of faith, community, caregiving, and justice work.  And he hopes to develop experiential education programs that expose and sensitize others to the plight of marginalized groups.  He would welcome talking with congregations about these and related topics.

Mark Lee

Phone: 970-495-0792

Mark is the Director of Christian Formation for Adults at Plymouth UCC in Fort Collins. During the school year, his availability is sketchy; he is more available during the summer when there are not regular Formation events in his home congregation. He serves as the ONA Coordinator for the RMC, so has particular expertise speaking to ONA issues. The rest of the time, he is a dedicated lectionary preacher, who likes that the lectionary makes him grapple with texts he otherwise might avoid. His D.Min from Iliff focused on homiletics, and so he employs a variety of preaching styles. He also raises goats, stories of which often creep into his sermons! How come goats get such a bad rap in the Bible?
