Who We Are
Built by our community, for our community.
We created Ancestra from a place of deep care for people, community, and the ways healing can unfold when we are truly seen and supported. We are a BIPOC women-led nonprofit bringing together plant medicine, mental health, community care, education, lived experience, and cultural humility. We believe wisdom lives in many places: in professional training, yes, but also in the body, in our cultures and families, in the land, in our ancestors, and in the relationships that remind us who we are. At the heart of Ancestra is our hope to create spaces where people can feel welcomed, respected, connected, and held in the fullness of who they are.
Mária Osero, LNMF
Founder · Facilitator
Mária's work sits at the intersection of clinical psychology, somatic practice, psychedelic care, and liberation. Shaped by diasporic lineage and years in medical and mental healthcare, she is especially drawn to creating spaces where people who have felt unseen by traditional systems can feel fully human, deeply respected, and capable of trusting their own inner knowing.
Sharon Whitefawn, MA
Facilitator · Holistic Counselor
Sharon brings more than three decades of transformational healing work together with counseling psychology, meditation, trauma-informed movement, spirituality, and expanded states of consciousness. A grandmother, elder, and teacher, she brings a grounded warmth to the work and a deep commitment to balance, presence, community, and reciprocity with the living Earth.
