About Us


At MST Services, we're on a mission to transform the lives of troubled youth and their families. Our approach, Multisystemic Therapy®, is scientifically proven. We'll do whatever it takes to reach families in need so that their children can realize their potential.



Unquestionably, the disparity in minority youth coming in contact with the justice system is a problem. Multisystemic Therapy (MST) has been shown to be part of the solution. MST is a family-driven treatment that is culturally responsive and centered in homes and communities. When partnered with law enforcement and the juvenile justice system, it plays a unique bridge-building role in achieving shared outcomes for minority youth, families, schools, and communities at large. For more information on how MST helps combat racial disparity in the juvenile justice system, click here.


Our team of Ph.D. and Master level mental-health specialists train providers to implement Multisystemic Therapy. We deliver ongoing support and consultation to our partners to ensure the highest quality clinical outcomes. In many cases, MST collaborates with Network Partners, which are prominent youth services organizations that are responsible for clinical quality and consistency.
