About Grand Lake Mental Health Center Inc
Grand Lake Mental Health Center Inc, located in Kansas, Oklahoma, offers outpatient and intensive outpatient substance abuse treatment for a wide range of individuals — including adolescents, veterans, and adults navigating co-occurring disorders. With CARF accreditation and a structured 12-week IOP, the center serves those building long-term recovery outside of a residential setting.
Grand Lake Mental Health Center Inc is a CARF-accredited substance use treatment facility situated in Kansas, Oklahoma, in Delaware County. The center focuses on outpatient addiction treatment and mental health support, making it a practical option for individuals who are ready to engage in structured recovery programming while maintaining their daily lives and community connections. Led by CEO Josh Cantwell, the organization operates Monday through Friday and accepts a broad range of payment options including Medicaid, Medicare, TRICARE, private insurance, and self-pay.
The center offers two distinct levels of outpatient care: a standard Outpatient Program and an Intensive Outpatient Program (IOP). The IOP runs on a defined 12-week schedule, providing a more concentrated treatment experience suited to individuals who need consistent structure but do not require residential treatment. Both program tracks are designed to support people at various stages of their recovery journey, from those stepping down from a higher level of care to those entering treatment for the first time.
Clinical work at Grand Lake Mental Health Center is grounded in Cognitive Behavioral Therapy (CBT), an approach that helps clients identify and reshape thought patterns that contribute to substance use and emotional distress. The center also addresses trauma and PTSD alongside addiction, recognizing that co-occurring disorders are often central to a person's recovery needs — not peripheral to them. This dual diagnosis capacity means clients do not have to choose between mental health support and substance abuse treatment.
Grand Lake Mental Health Center serves a notably broad population, including adolescents, young adults, seniors, men, women, pregnant women, veterans, court-ordered individuals, and people who are Deaf or hard of hearing. TRICARE acceptance makes the center an accessible option for military families in the region. For anyone in northeastern Oklahoma evaluating outpatient programs that can address both addiction and underlying mental health conditions, Grand Lake Mental Health Center offers a clinically structured, community-accessible path forward.
Outpatient & IOP Addiction Treatment in Kansas, Oklahoma
Grand Lake Mental Health Center Inc provides outpatient substance abuse treatment and a 12-week Intensive Outpatient Program (IOP) for adults, adolescents, and specialized populations in Delaware County, Oklahoma. The IOP's defined 12-week structure gives clients and their families a clear framework for what treatment looks like — an important factor when someone is weighing outpatient care against more intensive residential options.
Both the standard Outpatient Program and the IOP allow clients to remain connected to their homes, jobs, and communities throughout treatment. For many people in longer-term recovery, that community connection is not a compromise — it is part of what makes recovery sustainable. The center's Monday-through-Friday schedule supports consistent engagement without requiring clients to step away from everyday responsibilities entirely.
Co-Occurring Disorders & Dual Diagnosis Support
One of Grand Lake Mental Health Center's defining clinical strengths is its capacity to treat co-occurring disorders — meaning clients dealing with both a substance use condition and a mental health diagnosis like PTSD or trauma receive integrated care under one roof. Treating these conditions separately often leaves gaps; addressing them together is central to how the center approaches recovery.
Cognitive Behavioral Therapy (CBT) serves as the clinical foundation, helping clients build practical skills for managing triggers, emotional distress, and the underlying patterns that fuel substance use. For individuals whose addiction is intertwined with trauma history — a common reality for veterans, survivors of adverse experiences, and others — having trauma-informed, dual diagnosis care available in an outpatient setting is a meaningful distinction.
Who Grand Lake Mental Health Center Serves
Grand Lake Mental Health Center is built to serve a genuinely wide population. The center accepts adolescents, young adults (18–25), seniors, men, women, pregnant women, veterans, court-ordered clients, and individuals who are Deaf or hard of hearing. This breadth is not incidental — it reflects a center designed to meet people where they are, regardless of age, background, or circumstance.
Veterans and military families benefit from TRICARE acceptance, removing a significant financial barrier. Court-ordered clients have access to the same clinical programming as voluntary participants. Payment options span Medicaid, Medicare, private insurance, state insurance, TRICARE, and self-pay, meaning financial situation is less likely to stand between someone and getting started with treatment.
