Gateway Foundation - Caseyville

Integrated Treatment for Substance Use and Mental Health

The program treats substance use disorders alongside co-occurring conditions such as anxiety, depression, PTSD, anger, codependency, and chronic stress. Rather than separating mental health and substance use services, the team uses an integrated approach so clients can work on both areas at the same time. Treatment includes cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), motivational interviewing, mindfulness practices, individual psychotherapy, group therapy, and family or couples sessions.

Medically Supported Detox and MAT

Clients experiencing alcohol or opioid withdrawal receive close monitoring for issues like insomnia, anxiety, appetite changes, or seizure risk. Education is built into the detox process, helping clients understand how withdrawal may unfold and how lingering symptoms can be managed once they step into residential or day treatment. When clinically appropriate, the team can use medications for addiction treatment (MAT) to reduce cravings and stabilize brain chemistry. MAT is paired with therapy to help clients maintain progress as physical symptoms improve.

Age- and Gender-Specific Programming

Caseyville structures its programs by age group along with gender-specific groups. This helps clients talk openly about challenges that differ across life stages, such as college transitions, career or family strain, or health changes later in life. Gender-specific groups offer space to discuss patterns in relationships, trauma, communication, and recovery expectations with peers who share similar experiences. The program also supports clients with trauma histories through therapies designed to build emotional regulation and reduce reactivity in early recovery.

Aftercare, Alumni Community, and Practical Support

Aftercare planning begins before discharge and may include outpatient counseling, 12-step meeting access, or support connecting to recovery homes or sober living environments. Gateway’s alumni program offers continued peer support, educational programming, and opportunities to stay connected with staff and fellow graduates. Case management services assist with practical needs — such as navigating legal requirements for court-ordered treatment or connecting with community resources — to reduce barriers that can disrupt early recovery.

Client Reviews

Overall, reviewers report mostly positive experiences with this program’s care, staff, and environment. A smaller share raise concerns about specific staff interactions, communication, or discharge decisions.

• Treatment Quality & Outcomes (90% positive): Many reviewers say the program gave them structure, tools, and hope to stay substance-free after treatment. A smaller group felt the curriculum or follow-up care didn’t fully match their needs. "Gateway showed me the way to save my life!"
• Staff & Care Experience (90% positive): Clients frequently describe staff as compassionate, encouraging, and genuinely invested in their recovery. Some reviews note inconsistent communication or staff who seemed less prepared to manage complex mental health concerns. "They have the best staff and the people really care about you"
• Facility & Environment (80% positive): Reviewers describe a comfortable setting with structured days and decent food. Some describe the atmosphere as busy or stressful, especially when groups feel large or discharge feels rushed. "Clean facility, great food, knowledgeable staff."
• Support & Community (80% positive): Several reviews highlight strong peer support, helpful groups, and family involvement that make people feel less alone in early recovery. A smaller number wish for more social connection or support once they leave the program. "Couldn't be a better place to support someones recovery journey!"
