Crownview Psychiatric Institute's supportive local setting

When a severe mental health disorder disrupts your ability to participate in the basic activities of daily life, you may need to spend time away from your typical daily environment and the factors that exacerbate the symptoms of your disorder. Our residential treatment program gives you the time and space you need to get the individualized, targeted care that can help you work toward a full, fulfilling, and independent life.

Time spent in immersive residential treatment – where your only goal is to learn, heal, and grow – can make all the difference. We specialize in supporting patients with challenging disorders, patients who have not experienced success in other programs, and patients who need the expert guidance of skilled treatment professionals who specialize in complex mental health disorders.
