About Gateway Foundation Caseyville
Gateway Foundation Caseyville is a Joint Commission-accredited drug and alcohol rehabilitation facility located at 600 W Lincoln Ave in Caseyville, Illinois, serving St. Clair County and the surrounding Metro East region. The center operates under the Gateway Foundation network and provides a structured continuum of addiction treatment services for adults seeking help with substance use disorders.
The facility’s levels of care span from detox through long-term recovery support. Detox services form the entry point for individuals requiring supervised withdrawal management before transitioning to further treatment. From there, patients can step into residential programming, which provides around-the-clock structure, or into outpatient services for those who need flexible scheduling. A recovery home option extends support beyond primary treatment, and virtual/telehealth services are also available for eligible individuals.
Gateway Foundation Caseyville operates under Joint Commission accreditation — a nationally recognized standard that reflects the facility’s commitment to consistent, accountable care delivery. The center also maintains alumni engagement programming as part of its aftercare support structure, providing continuity for individuals who have completed primary treatment. Operating hours run seven days a week, with extended availability on Mondays, Thursdays, and Fridays.
This facility is suited for individuals at various stages of their addiction treatment needs — from those requiring initial detox and withdrawal management to those seeking residential stabilization or ongoing outpatient care. The combination of detox capability, multiple levels of care under one network, Joint Commission accreditation, and an alumni engagement component makes Gateway Foundation Caseyville a full-spectrum option for people in the Caseyville, IL area looking for structured, accountable addiction treatment.
