Services
Inpatient Treatment
Our inpatient program provides 24/7 medical supervision for severe mental health crises and addiction withdrawal. Patients receive individualized treatment plans combining psychiatric assessment, medication management, and evidence-based therapies. This structured environment ensures safety while addressing acute symptoms through group therapy, family sessions, and relapse prevention strategies.
Partial Hospitalization
This intensive daytime program offers structured mental health care without overnight stays. Patients attend 9am-3pm sessions focusing on cognitive behavioral therapy, stress management, and medication monitoring. It bridges inpatient care and outpatient treatment, providing crisis stabilization while maintaining home life continuity through five-day weekly programming.
Intensive Outpatient
Flexible outpatient treatment accommodates work and family commitments with morning, afternoon, or evening sessions. Patients engage in trauma-informed therapies, relapse prevention, and skills training three days weekly. The 12-week evening program specifically addresses PTSD, anxiety, and substance use disorders through evidence-based group and individual counseling.
Dual Diagnosis Care
Specialized programs simultaneously address mental health conditions and substance use disorders. Our integrated approach combines psychiatric care with addiction counseling, using medication-assisted treatment and cognitive behavioral therapy. This comprehensive model treats depression, bipolar disorder, and PTSD alongside alcohol or opioid addiction through coordinated inpatient and outpatient services.
First Responder Programs
Tailored mental health support for law enforcement, firefighters, and EMTs experiencing trauma-related disorders. Confidential assessment routes through dedicated intake lines connect first responders with trauma specialists. Treatment incorporates evidence-based therapies like cognitive processing therapy and biofeedback to address job-related stress and PTSD symptoms.
