Staff at Williston-Immanuel United Church

Rev. Reba Delzell


Reba graduated from University of Oregon in 1992 with a BA in Sociology and the Pacific School of Religion in Berkeley in 1998 with her MDiv. She is an Ordained Minister with full standing in the UCC and was ordained in 2001. She has served churches in Vermont, Arizona, and Oregon and hospitals and hospice centers in California and Oregon. She is married with two adult children—the youngest, her daughter, begins college this fall. Rebecca writes, “I am passionate about grace-filled transformations: those life-altering ah-ha moments that leave us forever changed for the better; or the arduous sojourns that finally lead us to sanctuaries of peace and serenity. I seek in my life and my work to create fertile ground that enables individuals to experience their own life transformations.”
