LSSI provides a range of treatment options to help individuals with alcohol and/or drug disorders. Our services include medically-assisted detox, some residential rehabilitation, extended aftercare (sober living facility), and outpatient treatment. LSSI's treatment services are licensed by the Illinois Department of Human Services Division of Alcoholism and Substance Abuse (DASA). LSSI works in financial partnership with the federal government, the state of Illinois, and townships to offer services to persons who are economically disadvantaged. Funding is available for all whose incomes meet DASA eligibility requirements, which are based on the federal poverty guidelines.
