Increasingly, peer recovery support services (PRSS) are an important—and sometimes central—part of efforts to effectively address illicit substance use and misuse. Altarum believes that peer-based services are vital to the continuum of care for individuals impacted by substance use disorder. Altarum works with organizations and systems as they implement best practices and promising approaches related to PRSS. Altarum supports federal, state, and local governments, as well as national and community-based organizations, to build a system of care that focuses on recovery, active involvement of consumers and their families, and multiple services to best meet individual needs and to strengthen and improve the health of communities.
