Mary DeJong is the founder of Waymarkers, LLC. She lives in Seattle, Washington’s Rainier Valley in Columbia City, at Hedgewood, a home that for over a decade has hosted community connection through the reclamation and restoration of a neighborhood forest. As a long-time urban naturalist, and practitioner and guide of place-based pilgrimage, DeJong received her Masters in Theology & Culture from The Seattle School of Theology & Psychology and earned her Religion and Ecology certification from Yale’s Divinity School and School of Forestry, overseen by Mary Evelyn Tucker, John Grim, and Brian Swimme. Her academic focus within ecological theology and specialization in Thomas Berry’s Universe Story delves into why place matters and the sacramentality of the more-than-human world.

Influenced by the lives of Celtic saints, Jospeh Campbell’s The Hero’s Journey and the emerging field of ecopyschology, Mary facilitates retreats and pilgrimages in the Pacific Northwest and in Iona, Scotland, that strengthen the unique and mystical interconnection of participants, the sacred, and the natural world. She has studied and practiced within the Celtic spiritual tradition, her own maternal line heritage, for over twenty years, including studying under John Philip Newell through the School of Celtic Consciousness.

Her husband, four children, ten chickens, a duck, a feral kitty, a medicinal and herb garden, and yard—a Certified Wildlife Habitat—keep her busy when her pen does not.
