Core offering

Timberline Knolls Residential Treatment Center provided a full continuum of trauma-informed behavioral healthcare exclusively for women (18+) and adolescent girls (12-17), including residential treatment, partial hospitalization, and intensive outpatient programs. Treatment addressed eating disorders, substance use disorders, trauma and PTSD, mood disorders, and co-occurring conditions, using evidence-based modalities (DBT, CBT, ACT) combined with experiential therapies, and supported by adjunct on-campus schooling and a faith-based care track.

Product overview

Age-appropriate services are provided in gender-specific settings. Adjunct offerings include TK Academy for academic continuity, The Grace Program for faith-based care, Experiential Therapies (art, dance/movement, yoga), and an Alumnae Services program for ongoing post-discharge support.
