Paul completed his undergraduate work at CU Boulder, majoring in mathematics and physics. This part of his journey included a transformative year through the Study Abroad Program at the University of Lancaster, England.  His academic and career interests shifted, however, and Paul received his Ph.D from the University of Denver and Iliff School of Theology in the “Religion and Social Change” program.  After some years teaching around the state, Paul was invited to become the Director of the CU Residential Honors Program and teach classes in ethics and nonviolent social change.  His research and writing are focused on nonviolent social movements as well as “community building” in campus residential halls.  Paul was the Faculty in Residence in Smith Hall at CU for the Honors Program and has now returned to his home in the mountains.  In addition to his studies he is working on his photography and a memoir.  You can see Paul on his bicycle on campus or on the trails in Rocky Mountain National Park.

Sam BullingtonSam Bullington, Ph.D.

Sam Bullington is passionate about the transformative power of inspired teaching.  An overarching goal of his pedagogy is to help students make conscious what they’ve been trained to keep unconscious, and watching students come to insights about themselves and their place in the world constitutes the most satisfying aspect of teaching for him. Sam is a social scientist with training in Anthropology, Geography, and Environmental Studies and a Ph.D. in Feminist Studies from University of Minnesota.  He did his academic research in South Africa where he worked with LGBT and AIDS activists. As a transsexual, he has a unique and broad understanding of gender, as well as social categories more generally.

Since the election, Sam has been leading workshops on unlearning racism, toxic masculinity, and decolonizing teaching, as well as engaged spirituality/spiritual activism. Sam founded and directs Phoenix, Colorado’s Transgender Community Choir and has had a lifelong interest in the role of music in social justice movements. When not teaching or leading Phoenix, Sam has a shamanic counseling practice, leads vision quests, and is currently writing a book—part memoir, part gender studies, part spiritual teaching—called Transgender Wisdom: What I’ve Learned about Gender and Life from Living in the Grey Areas.
