About Gateway Foundation

Gateway Foundation, now operating under the name Alpharus Health, is a long-established addiction and mental health treatment provider with a location in Belleville, Illinois. With nearly 60 years of experience, they treat alcohol and drug use disorders, including opioids such as fentanyl and kratom, stimulants, marijuana, benzodiazepines, and hallucinogens, along with co-occurring mental health conditions and gambling problems. Across their network, care ranges from medically supported withdrawal management and 24-hour residential treatment to outpatient programming and confidential virtual sessions. Their approach starts by matching each person to the right level of care and tailoring treatment to the substances involved, the severity of dependence, and any related medical or mental health needs.

During detox, clinical staff monitor patients around the clock, use medication to ease opioid and alcohol withdrawal, and add therapy to help with lingering anxiety, restlessness, and sleep problems. Their medication-assisted recovery program pairs counseling with FDA-approved medications such as buprenorphine (Suboxone) and naltrexone (Vivitrol), and patients already receiving methadone from another provider may be able to continue it through coordinated care. Therapy explores how trauma, behavior patterns, and mental health contribute to substance use, and the broader program also includes DUI services, support groups, specialty tracks, and an alumni network. They accept most major insurance plans and also run a corrections division that provides treatment in jails and other justice settings to help people prepare for life after release.
