About Multisystemic Therapy (MST)
Multisystemic Therapy (MST) is an in-home, family-driven, community-based treatment for youth. The overarching goal of MST is to keep youth at home, in school, and engaged in pro-social activities. Through an intensive, yet relatively short-term (3-5 months) approach, MST therapists aim to uncover and assess the functional origins of adolescent behavioral problems across the different systems that impact the youth and family.
MST is delivered to a youth (ages 12-17) and their family by a therapist who is part of a small team of 2-4 therapists plus a supervisor who is fully dedicated to providing the MST model with 24/7 availability. Because MST is delivered in the home and community, each MST team has a service delivery area that can expand up to 90-minutes from the office.
