About This Facility

About Gateway Foundation Inc

Gateway Foundation Inc is a comprehensive alcohol and drug rehab center serving individuals and families in Caseyville, IL and the surrounding region. Located at 600 West Lincoln Street, this facility specializes in treating substance use disorders and co-occurring mental health conditions for men, women, and individuals with dual diagnoses. Gateway Foundation Inc provides evidence-based treatment in a supportive environment designed to meet each person's unique recovery needs.

Treatment Programs at Gateway Foundation Inc

Gateway Foundation Inc offers multiple levels of residential care to support recovery at different stages. Detoxification services help individuals safely manage withdrawal symptoms under medical supervision, often serving as the first step toward recovery. Residential short-term treatment (30 days or less) provides intensive, structured care for those who need focused intervention and stabilization. For individuals requiring extended support, residential long-term treatment (30 days or more) offers ongoing therapeutic services and skill-building in a residential setting. The facility also specializes in co-occurring disorder treatment, addressing both substance use and mental health conditions simultaneously with integrated care. Gender-specific programming for both men and women ensures that treatment can address sex-specific needs, trauma, and recovery goals in a comfortable, appropriate setting.

Insurance & Payment at Gateway Foundation Inc

Gateway Foundation Inc accepts self-payment options, making treatment accessible to individuals paying out-of-pocket. While navigating payment and insurance can feel overwhelming during a crisis, Gateway Foundation Inc works with individuals to discuss financial options and create a treatment plan that fits their circumstances. If you have insurance coverage, many plans provide benefits for substance abuse treatment and mental health services under the Mental Health Parity Act, which requires equal coverage for behavioral health and medical conditions.

If you or a loved one is ready to take the next step toward recovery, Gateway Foundation Inc is ready to help. Call (618) 345-3970 today to speak with an admissions specialist who can answer your questions about treatment options, verify your insurance, and help you begin your recovery journey. Recovery is possible, and reaching out is a sign of strength—not weakness.
