Dr. Tina Schermer Sellers, PhD, LMFT, CST‑S is a Swedish American therapist, educator, and author whose childhood on her grandparents’ homestead near Puget Sound—within Coast Salish territory—deeply shaped her values of community, resilience, and land stewardship.

Now residing in Sandy, Oregon—on the lands of the Cayuse, Umatilla, Walla Walla, and Clackamas Peoples—she lives with her partner on sacred wooded acreage. There, at Blackberry Retreat Center, she offers retreats and trainings for clinicians on the 4‑D Wheel for Expansive Integration and psychedelic-assisted therapy. As the first in her immigrant family to earn an advanced degree, Tina spent nearly three decades as a professor of marriage and family therapy, medical family therapy, and human sexuality before authoring two influential books: Sex, God & the Conservative Church and Shameless Parenting, both recognized for their impact on healing religious sexual shame and trauma, and empowering relational intimacy.

She is the founder and chief advisor to the Northwest Institute on Intimacy—offering postgraduate clinician training in sex therapy and relational health—and Founder and Executive Director of Inanna Rising, a clinician membership collective dedicated to equitable, just, and patient-centered psychedelic-assisted therapy training and support for activists and clinicians.

Dr. Tina remains committed to social justice, integrity, and weaving cutting edge cultural, spiritual, and sexual healing into a compassionate praxis. You can follow her on Instagram at @DrTinaShameless and @Inanna_Rising_PAT
