Connected Care

Chestnut Health Systems provides a wide range of services in Illinois and Missouri. Our caring and experienced staff work together to provide high-quality support to the people and communities we serve. Whether it’s substance use and recovery support, primary health care, or mental health services, we focus on improving lives and making a difference.

We connect care across these main areas:

  • Substance Use Support: Treatment, recovery, and prevention programs for drug and alcohol use.
  • Mental Health Care: Treatment and housing for people living with mental health challenges.
  • Primary Health Services: Medical care and preventative health services for all ages.

By connecting care across these services and collaborating to link individuals with other needed resources, we ensure people receive whole-person, coordinated care to heal, grow, and thrive. This approach supports every aspect of their health, making it easier to achieve long-term recovery and an improved quality of life.
