As evidence-based practice is becoming integrated into children's mental health services as a means of improving outcomes for children and youth with severe behavioral and emotional problems, therapeutic foster care (TFC; a specialized treatment approach for such youth) is one of few community-based programs considered to be evidence-based. "Together Facing the Challenge" (TFTC) which was tested in a randomized trial of TFC has been identified as an evidence-based model. We describe the experiences reported by one of the agencies that participated in our study and how they have incorporated TFTC into their on-going practice. We highlight key implementation strategies, challenges faced, and lessons learned as the agency moved forward towards full implementation of TFTC. © 2013 Springer Science+Business Media New York.
