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 has served churches in Vermont, Arizona, and Oregon and hospitals and hospice organizations in California, Arizona and Oregon. She is married with two adult children and three grand-cats. 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 with God's grace and guidance to sanctuaries of peace and serenity. I seek in my life and my work to create fertile ground that enables individuals to draw closer to the Holy and experience their own life transformations and spiritual awakenings."
