Adult Residential Treatment Centers in Southern California

Residential treatment is one of the most all-encompassing forms of care for adults struggling with mental health conditions or substance use. Unlike outpatient therapy, where you go home each night, residential care provides a safe, structured environment where your only focus is healing.

At Aurora Charter Oak, our clients find that when they can step away from the pressures of work, relationships, or financial responsibilities, they can finally devote the time and energy needed to recover. Our residential treatment program is specifically designed to provide that safe, supportive, and dedicated space where healing can happen and forward progress becomes possible.

Choosing treatment at the Aurora Charter Oak Residential Treatment Center (RTC) means entering an environment where support is available 24/7. That might look like a nurse checking on you in the middle of the night when anxiety spikes, or participating in a group session that helps you process emotion in real time. You’ll also find a balance of structure and flexibility, with therapeutic experiences that build coping skills alongside activities that encourage growth, expression, and joy.

The Southern California setting adds another layer of benefit. Our campus, located adjacent to the Aurora Charter Oak Hospital in Covina, provides a quiet, landscaped atmosphere that encourages calmness and reflection. When you enter our RTC program, you’re not just getting medical and psychiatric support; you’re choosing to immerse yourself in a complete system of recovery built to help you stabilize, gain clarity, and prepare for life after treatment.

Our Programs & Services

The Aurora Charter Oak Hospital and Residential Treatment Center offers a continuum of care that meets adults where they are in their recovery journey. For those in crisis or experiencing severe psychiatric symptoms, our inpatient behavioral health services provide 24-hour monitoring and stabilization.

During inpatient treatment at Charter Oak Hospital, you’ll also meet with psychiatrists and other medical professionals who carefully assess your needs and prescribe the appropriate level of care. Therapy is offered in various formats, including individual sessions for private exploration, group therapy to learn and share with others, family therapy to strengthen support systems, and expressive therapies that utilize art, movement, or music as tools for healing.

For adults struggling with substance use, we provide medically supervised detox to ensure safety during withdrawal, followed by residential rehabilitation. Our Residential Treatment Center (RTC) focuses on recovery through structured programming that typically lasts two to four weeks.

While in the RTC, you’ll live in private rooms, participate in recovery groups, and engage in relapse prevention education. If you’re dealing with both addiction and a psychiatric disorder, our dual-diagnosis track ensures that both issues are addressed simultaneously, rather than separately. This integrated approach reduces the risk of relapse and helps you develop strategies that tackle the full scope of your challenges.

When inpatient or residential care is no longer needed, our outpatient programs provide step-down support. The Partial Hospitalization Program (PHP) is the most intensive, offering full-day treatment during the week. The Intensive Outpatient Program (IOP) is more flexible, meeting fewer days per week and allowing you to reintegrate into daily life while still receiving therapy and psychiatric care. Together, these programs create a seamless path from crisis stabilization to long-term recovery support, ensuring you’re not left on your own after discharge.

Who We Serve

Aurora Charter Oak Hospital serves adults (age 18+) who are facing mental health disorders, substance use issues, or both. Many people who seek our services are in crisis, experiencing acute psychiatric symptoms such as severe depression, mania, psychosis, panic attacks, or suicidal thoughts. Others may be struggling with addiction that has taken control of their lives, whether it’s alcohol, opioids, or other substances.

Often, individuals who come to us have tried outpatient therapy or medication management but have found those approaches insufficient on their own. The Aurora Charter Oak Hospital and RTC provide the higher level of care needed when less intensive methods aren’t enough.

We also specialize in treating adults with dual diagnoses, meaning those who have both a mental health condition and a substance use disorder. Research indicates that these conditions often reinforce one another. Untreated mental illness can drive someone to use substances as a form of self-medication, while substance use can worsen psychiatric symptoms or trigger new ones. At Charter Oak, our programs are structured to address these issues together. That way, you don’t have to bounce between facilities or treatment teams; you can receive comprehensive care in one place.

Our admissions are inclusive, welcoming adults from diverse cultural, social, and economic backgrounds. We work to understand each person’s unique situation, whether that involves long-standing trauma, recent life stressors, or chronic health issues. We know that no two recovery journeys are alike, so every treatment plan is tailored to the individual. Families are also encouraged to be involved, since recovery often depends on a strong support network.

If you’re an adult who feels trapped by mental illness or addiction, or if you’ve tried other options and need something more intensive, Aurora Charter Oak is designed for people just like you.

What Sets Us Apart

Aurora Charter Oak Hospital and RTC distinguishes itself through its combination of expertise, environment, and commitment to whole-person care. One of our strongest advantages is our multidisciplinary team approach. Psychiatrists, internists, nurses, therapists, social workers, expressive therapists, and case managers collaborate on every case. This ensures that your treatment isn’t one-dimensional. Instead, it reflects a balance of medical intervention, therapeutic support, and practical guidance for life outside treatment. By working together, our team can adjust your plan as you progress, making sure care remains responsive and effective.

The physical environment also plays a significant role in our top-tier care. Our facility is located on a ten-acre landscaped campus in Covina, California. The setting is calm, quiet, and far away from the chaos of everyday life. Our patients often note that the campus feels more like a retreat than a hospital or institution, which makes it easier for them to focus on their healing.

Private rooms in the RTC also provide comfort and dignity, while shared therapeutic spaces foster a sense of community and peer support. The entire campus design reflects our philosophy: recovery should be about more than just symptom reduction; it should also create opportunities for peace, reflection, growth, and change.

Another defining feature is our integrated dual diagnosis care. Many facilities still separate mental health treatment from addiction services, but at Charter Oak, we see the two as deeply connected. Our dual diagnosis programs enable patients to address both aspects of their struggle simultaneously, leading to a more lasting recovery.

We also offer medication-assisted treatment integrating medical solutions with therapeutic care. Beyond the treatment itself, we invest heavily in aftercare and discharge planning. From day one, we prepare you for what comes next by connecting you to outpatient services, aftercare groups, and community resources, ensuring that the progress made here continues long after you leave.

Insurance & Payment Options

We understand that navigating insurance and payments can be stressful, and we want finances to be the last thing holding you back from getting the care you need. As a result, Aurora Charter Oak Hospital accepts a wide range of insurance plans, including many PPO providers, as well as Medi-Cal and Medicare for certain programs.

The Charter Oak Residential Treatment Center (RTC) operates slightly differently. The RTC accepts most PPO insurance plans in our region, as well as some HMO plans, including Kaiser. However, we do not accept Medi-Cal or Medicare. In these cases, private pay is available, and our financial team can provide clear estimates to help you make an informed decision. Because recovery is too important to delay, we also offer payment plans that allow you to spread costs over time.

Before admission, our counselors will verify your coverage and explain how co-pays, deductibles, or out-of-network benefits apply. If your insurance is out of network or if you don’t currently have coverage, our team can help you explore alternatives or connect you with facilities covered under your plan.

Our goal is to minimize financial uncertainty so you can focus entirely on healing. With flexible options, experienced guidance, and a commitment to affordability, we make high-quality mental health and substance use treatment accessible to people from all walks of life.

Admissions Process

Beginning treatment at Aurora Charter Oak is straightforward and supportive. The process starts with a free, confidential assessment that can be scheduled at any time of day or night.

When you call our admissions line, a trained staff member will ask questions about your current symptoms, medical history, substance use, and any immediate safety concerns. This information helps us determine the most appropriate level of care for your situation.

If you are in need of inpatient stabilization or medical detox, we’ll arrange for admission as quickly as possible. If outpatient care is more suitable, we’ll explain your options and help you get started. Once admitted, you’ll undergo a more detailed evaluation by psychiatrists and other medical professionals. This evaluation serves as the foundation for your personalized treatment plan.

During inpatient or residential treatment, you’ll participate in therapy, receive medication management if needed, and have access to expressive, art, and recreational therapies. Family members are often included in treatment planning, since their involvement can be critical to long-term recovery. In outpatient programs, the process is similar, but you’ll attend scheduled sessions during the day or evening while continuing to live at home.

Discharge planning begins early, sometimes within the first few days of admission. We know recovery doesn’t end when you leave our facility, and our case managers work with you to identify follow-up care, whether that’s outpatient therapy, support groups, sober living, or ongoing medication management.

Many RTC graduates also participate in free aftercare groups for up to a year, which provides an immense layer of continuity and support. Throughout the process, our staff remains committed to ensuring you feel supported and informed. From your first phone call to your final day in treatment, you’ll know exactly what to expect and how we’ll help you along the way.

Patient Experience

Patients at Aurora Charter Oak often describe their experience as transformative. From the moment you arrive, our staff will make it clear that you’re more than just a diagnosis; you’re a person with a story, a family, and a fantastic future. That perspective shapes everything we do.

Our team also strives to create an environment of dignity and compassion, so you feel safe sharing the struggles that brought you here. In therapy sessions, you’ll find space to explore painful experiences and learn healthier ways of coping. In group settings, you’ll connect with others who are facing similar challenges, gaining encouragement and insight from shared experiences.

Life in treatment isn’t only about clinical interventions. Our expressive therapies give you outlets for creativity and self-expression that words alone sometimes can’t capture. Recreational activities and outdoor time on our landscaped campus help reduce stress and build resilience. Private rooms in our RTC provide space for rest and reflection, while common areas encourage connection and community. Every aspect of the patient experience is designed to balance healing, learning, and recovery.

Many of our patients leave with more than just symptom relief. They report feeling hopeful again, regaining confidence, and repairing strained relationships with loved ones. Families often notice improvements in communication and understanding, thanks to family therapy sessions that help rebuild trust.

Aftercare

Support doesn’t end at discharge. With aftercare groups, ongoing outpatient options, and relapse prevention planning, you’ll have resources to maintain progress. Recovery is a lifelong journey, but our goal is to give you the tools, confidence, and community to continue walking that path long after you leave our campus.

At Aurora Charter Oak, the patient experience is about more than treatment; it’s about rediscovering who you are and building a future you can look forward to.
