Located at 151 N. Main Street in Decatur, Illinois (Downtown Decatur). Heritage Behavioral Health Center, Inc., celebrated it's 50-year anniversary in 2006, tracing its origin back to March 1, 1956. Then known as the Mental Health Clinic, accepted its first client on April 10 and has been providing continuous service ever since. In 1967, the Alcoholism Advisory Council for the Decatur Area was established to provide substance abuse services. In 1970, the Mental Health Clinic became the Decatur Mental Health Center and established an inter-locked relationship with the Alcoholism Advisory Council. In 1987, the Alcoholism Advisory Council was merged into Decatur Mental Health Center. DMHC continued its steady growth and became the primary provider of community-based behavioral health care in Macon County.

In 1998, Decatur Mental Health Center became Heritage Behavioral Health Center, Inc. While our name and our services have changed over the course of our 53 year history, we have stayed true to the principles upon which we were founded, building a legacy of high quality services. Heritage provides comprehensive community-based services to treat the most serious behavioral disorders and links them closely with providers of inpatient care; we provide these services to over 4,000 people annually. We also provide a wide variety of innovative outreach, crisis intervention and prevention services in our communities.
