They have tvs in every room and good food. Lots of smoke breaks and they have a good medication management for symptoms. I would highly recommend them to anyone wanting a painless detox

This is a good place to work. We’ve had some turn over, yes, but the staff I have been working with for the last 8 months is very caring and all of us work hard to ensure proper patient care and safety. Most of the patients have a very positive experience here. I am proud of our nurses, and we all respect one another. I have not heard of anyone talking badly about anyone who works here. Every place has their challenges as I have worked at a few addiction treatment centers, and Banyan is one of the best places to work. I am responding to an inaccurate review that was left on here by a scorned nurse who was let go for being confrontational with a patient, and it was so unprofessional and incorrect. We have never had lice or bed bugs and that’s 100% a lie left on here by one nurse. I have referred other nurses and they’ve all been happy to be here.

Other Forms of Payment

Military members, veterans, and eligible dependents have access to specific insurance programs that help them get the care they need. TRICARE and VA insurance can help you access low cost or no cost addiction and mental health treatment. Programs that accept military insurance often have targeted treatment focused on the unique challenges military members, veterans, and their families face.

Financial aid can take many forms. Centers may have grants or scholarships available to clients who meet eligibility requirements. Programs that receive SAMHSA grants may have financial aid available for those who need treatment as well. Grants and scholarships can help you pai for treatment without having to repay.

Medicaid is a state based program that helps lower-income individuals and families pay for healthcare. Medicaid covers addiction treatment so those enrolled can use their coverage to pay for rehab. When a program accepts Medicaid the client often pays very little or nothing out of their own pocket.

Self-pay involves paying for treatment out of your own pocket. You can use savings or credit, get a personal loan, or receive help from family and friends to fund your treatment. If you don't have insurance or your insurance plan doesn't cover a specific program, self-pay can help ensure you still get the care you need.

Private insurance refers to any kind of healthcare coverage that isn't from the state or federal government. This includes individual and family plans offered by an employer or purchased from the Insurance Marketplace. Every plan will have different requirements and out of pocket costs so be sure to get the full details before you start treatment.

Addiction Treatments

Levels of Care

The inpatient rehab or residential rehab at Banyan Castle Rock is a premium environment for taking back the power over your life from drugs and alcohol. You’ll live in a healing and serene atmosphere with a community of others in recovery while you receive treatment every day that guides you toward a life of sustainable sobriety.

You’re probably familiar with 12 step addiction programs like AA and NA to some degree. Banyan Castle Rock takes a personalized approach to addiction treatment so they’ll create your treatment plan around what best suits you. This can include the 12 step philosophy if that method resonates with you. They encourage you to get involved in 12 step meetings outside the rehab during your program too.

Detox is the first step in your path to recovery and healing after addiction but you don’t have to do it alone. At this rehab they have a medically assisted detox program where the specialized medical staff will supervise your withdrawal process. They can use medications and medical interventions to keep you as comfortable as possible and make sure you’re safe throughout the process.

Banyan Castle Rock is on a mission to make addiction treatment accessible to as many people as possible and that includes people who can’t always come to therapy due to transportation issues or child care or other circumstances. In these cases they have telehealth treatment available so you can still get your treatment sessions and continue growing in your recovery.

Clients engaged in a rehab aftercare program have completed active addiction treatment and are receiving services designed to promote their sustained sobriety. Drug rehab aftercare typically encompasses a wide variety of medical, mental health, and social services meant to facilitate clients' reintegration into their home, workplace, and community. Clients typically collaborate with their case manager and/or recovery team to identify and access the services they need, often including peer coaching, career counseling, and care referrals.

Detox can be dangerous if not properly supervised, making 24-hour clinical care in Colorado an essential tool in the recovery process. The constant monitoring by medical professionals helps individuals through critical stages of recovery. Medical professionals and addiction specialists are available 24/7 to provide medications that ease withdrawal symptoms and to treat any other issues that arise.

Substance use disorder is a disease that needs to be treated with clinical care and compassion like any other condition.

For drug addiction or alcohol addiction or if you are facing substance abuse with co occurring mental health conditions, Banyan Castle Rock is a path to recovery.

Colorado offers dual-diagnosis addiction treatment programs that encompass various levels of care to meet your individual needs, including medical detox, outpatient, inpatient, and partial hospitalization programs for individuals with co-occurring mental health and substance use disorders. These dual-diagnosis rehab programs incorporate evidence-based therapies such as cognitive-behavioral therapy (CBT) or dialectical behavior therapy (DBT) to successfully address substance use disorders and co-occurring diagnoses.

Alcoholism is defined as a physical dependence on alcohol. In this state, the body experiences withdrawal symptoms in the absence of alcohol. Over time, a person with alcohol use disorder also must drink greater amounts of alcohol to achieve the same effects. To overcome alcohol use disorder, alcohol rehab in Colorado is usually necessary, a process which includes supervised medical detox. This is followed by intensive rehab, then a maintenance program that may include 12-step support.

Clinical Services

Group therapy in Colorado offers you a platform to share your stories about drug addiction and co occurring mental health conditions. You'll receive encouragement and empathy from peers who understand your journey, fostering a sense of community and belonging.

Men and women in Colorado have access to customized individual therapy sessions for drug and alcohol addiction treatment. These sessions explore your life experiences and patterns of substance abuse. Your therapist helps you recognize harmful behaviors and thoughts that empower you to make positive changes for lasting recovery.

During family therapy sessions, family members in Colorado work with therapists to understand addiction as a disease that has affected the entire family. This approach fosters empathy and reduces blame on any one member. Promoting this collective effort helps to support the recovery process.

The main principle of cognitive behavioral therapy (CBT) in Colorado is that substance use disorders are based on faulty thinking and behavior patterns. The goal of this treatment is to help the individual learn better ways of coping with challenges, which will lead to changes in thinking and behavior.

Creative arts therapy can take place in individual or group sessions. It may include reading poetry, journaling, making videos, or scrapbooking. These expressive activities allow participants to tap into emotions and process challenges in ways other than talking about their problems.

Eye Movement Desensitization and Reprocessing (EMDR) therapy is a structured, evidence based approach to help you process traumatic memories. It uses bilateral stimulation that typically includes eye movement but can also include tapping or auditory tones. This helps reduce your emotional stress and transforms negative thinking and beliefs into positive ones.

Dialectical behavior therapy is skills based and present oriented. You’ll be asked to keep a diary of emotions and related behaviors and practice the skills you’ve been learning between sessions. The focus of skills development is on mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.

During trauma therapy, you explore the impact that a traumatic event has had on your life. Your therapist can help you develop strategies to manage the emotional and physical symptoms while improving emotional regulation. This improves your overall quality of life.

Addiction therapy uses recreation to provide structured activities that replace substance use with positive experiences. For example, swimming, cooking classes, and hiking trips encourage social interaction and improve physical health and emotional stability. This helps you rebuild your life without relying on drugs or alcohol.

Life skills are traits you need to be successful during recovery, such as managing stress and interpersonal relationships. During rehab treatment in Colorado, you and your therapist will identify any skills that need to be developed and work on methods to strengthen them.

Therapists who employ motivational interview techniques seek to draw out the client's ideas about change and allow them to draw their own conclusions about the need for change. This method is often effective for clients who feel unsure about their ability to change or the need for change.

One star is too generous for the harm I experienced at Banyan Treatment Center in Castle Rock. My experience at this facility was deeply distressing and caused lasting emotional harm. The most serious issue was a violation of my privacy and confidentiality. The billing department contacted my parents demanding a $4,500 payment and disclosed that I was an inpatient resident in treatment. This occurred without my consent and directly undermined my intention to keep my treatment private. At the time, my family believed I was away on a church retreat. This was not due to shame, but because my decision to seek treatment was meant to be a hopeful surprise upon completion—especially after our family suffered unimaginable loss. My older brother passed away from brain cancer on January 13, 2026, at only 43 years old. Shortly after, my grandmother fell, broke her hip, rapidly declined, and also passed away. This was our first Christmas without our loved ones. I intentionally canceled travel plans, including airfare purchased by my parents, so I could begin treatment and later share that progress as something positive. That choice was taken from me. The disclosure felt like a profound betrayal of trust. When I raised this HIPAA concern with administrative staff, it was dismissed. I was told I had “signed a form,” despite clearly explaining that my family did not know I was in treatment. The lack of accountability and compassion in response to such a serious issue was devastating. I was also alarmed to see staff printing daily census reports that included patient photos, full names, and dates of birth. Seeing highly sensitive personal information handled so casually raised serious concerns about the facility’s approach to privacy, ethics, and patient protection. Beyond privacy issues, I experienced significant neglect regarding my personal property. My laptop was returned to me broken beyond repair, and personal belongings—including sentimental gifts such as new shoes symbolizing a fresh start and a hat—were taken by my roommate. When I reported this, I felt dismissed and unsupported. No one took responsibility for the damage to my laptop, which was especially harmful because my case manager and I were actively relying on it to submit critical FMLA and Colorado FAMLI paperwork to protect my job and income during treatment. Even more troubling, the broken laptop was quietly placed back with my locked belongings for me to discover later. Several staff members spoke to residents in a condescending and demeaning manner. One staff member in particular, Laura (BHT), consistently treated patients as though we were delinquents or children rather than individuals seeking recovery. This environment was not therapeutic—it was disempowering. The admissions team also informed us that gym access would be provided four days per week. This was misrepresented, and I missed my first opportunity because my shoes had been stolen and I no longer had the required footwear. Treatment environments should be safe, respectful, trauma-informed, and confidential. Instead, I left Banyan feeling more traumatized than helped. I truly believe I lost far more than I gained from this experience. Anyone considering this facility for themselves or a loved one deserves to be fully aware of these risks.

Oh where do I start with this place! I would give it zero stars if I could from the heavy processed food, to a nurse giving a patient 700 mg of the incorrect dosage of medication sending them to the hospital because they overdosed the patient. I hope that patient sues Banyan and files a Dora complaint against that nurse! To the numerous times other nurses gave patients’ the wrong medications and the patients’ catching the error before they took it! I could also see other patients’ information including their full names, DOB, etc….HIPAA violation. To the shower not even being cleaned between new patients’ arriving to the room. There were pubic hairs in our shower (gross) not ours and no water pressure. To the wasteful time of unproductive group. Also to mention patients’ arguing, physically fighting, and sexual encounters. Wouldn’t be surprised if there were some babies conceived during my time there. I could go on but the state/Government needs to investigate this place immediately! This place is ment for substance abuse not mental. This facility should not even be opened and should be shut down, but it definitely should not be dual diagnosis. Do not go here for mental or at all! Banyan I will file my complaints with city and state. No need to respond with your 1-800 number!

First off, I want to give a shout-out to the chefs and kitchen staff. Great food, which helped make the overall horrific experience there slightly more tolerable. There were times where I felt the place would be shut down at any moment due to the never ending chaos of patients yelling and screaming or having to be sent off to the hospital due to botched detox protocols. My personal experience with detox there has actually caused me long term health problems due to the fact the providers didn’t inform me that one of my medications needed to be tapered off for many months — not three weeks! I’m now dealing with a very serious protracted withdrawal disorder that has disrupted every aspect of my life since leaving there. Just throwing endless amounts of Valium and muscle relaxants at someone until they leave is medically irresponsible. I’m actually considering to sue this facility due to the pharmaceutical injuries I might have to deal with for the rest of my life. If you’re considering going here, I’ll make this simple by saying the following: research other facilities! Here are some additional reasons why you should consider somewhere else to spend your time and money: 1) you will be strip searched and dehumanized as soon as you arrive 2) you will then have to wear scrubs until they get around to vaporizing your personal belongings with a Zap Bug Oven to prevent even more bed bugs from contaminating the place 3) groups are poorly structured and a waste of time 4) there are tvs in every room, which can be distracting if you have a roommate who watches tv all day and all night 5) the clinical director is good at listening, but it’s quite apparent he doesn’t actually care about clients and operates with a superficial front Not cool. Not cool at all. “Love them while they’re here, but forget about them when they leave.” That’s their motto.
