About Us

Who We Are

The JEAP Initiative is a partnership between Chestnut Health Systems' Lighthouse Institute, Oregon Social Learning Center, and Sponsors, Inc., and is supported by the National Institute on Drug Abuse (R24DA051950).

Chestnut Health Systems was founded in 1973 and offers a comprehensive scope of behavioral health and human services. Chestnut’s research division, Lighthouse Institute, was established in 1986 with the mission to improve the quality of services through research, training, and publishing. It is one of few research groups in the country that primarily focuses on developing more effective approaches for recovery management, treating substance use as a chronic disorder, diversion from the legal/child welfare system, and implementation science. Lighthouse Institute's multidisciplinary staff conduct applied research, program evaluation, training, consultation, and implementation.

The Oregon Social Learning Center (OSLC) was founded in 1977 by a group of clinical psychologists whose work focused on the social development, learning, and prevention and treatment of behavior and emotional problems in the lives of children and adolescents. That focus has evolved and expanded into a mission to strengthen families, children, and communities through collaborative prevention and intervention research. Located in Eugene, Oregon, our multidisciplinary research center is dedicated to increasing the scientific understanding of social and psychological processes related to healthy development and family functioning.  

Founded in 1973, Sponsors is the foremost reentry organization in Oregon and has been particularly beneficial for justice-involved individuals in recovery. The organization seeks to improve outcomes for high risk groups, including supporting recovery, reducing homelessness and recidivism, increasing public safety, and enhancing the overall well-being of our community. In addition to transitional housing and wraparound services, Sponsors also offers long-term housing, mentoring/peer support, employment support, cognitive behavioral programs, and more. Sponsors regularly receives national recognition as a model for the use of evidence-based practices in reentry.

Community Boards

Our work is guided by three national Community Boards. Our Community Boards determine the research priorities for recovery support services, determine the selection of early career investigators for our Fellowship and Trainee programs, decide which pilot studies are funded, and participate in sharing research findings with the broader community.

  • Young Adult Community Board

    This board is made up of young adults (age 16-25) who are in recovery from substance use. 

  • Justice-Involved Community Board

    This board is made up of adults who are in recovery and who have former or current involvement with the juvenile or adult justice system.

  • Provider and Payor Community Board

    This board is made up of staff from organizations that provide or pay for recovery support services.
