TBRI®

Trust Based Relational Intervention (TBRI®) is a well-researched, attachment-based, trauma-informed, family-friendly intervention for complex trauma that we’ve been sharing about for years. All ORPARC family support specialists complete basic training in TBRI®. The evidence is clear: TBRI® works! In fact, TBRI® is even officially considered an evidenced-based model. Please reference our Attachment, Life Story Work and Trauma pages for more resources.

"Our children were harmed in relationship and they will experience healing through nurturing relationships." ~Dr. Karyn Purvis - author in ORPARC's library
