Co-occurring disorders — also called dual diagnosis — affect millions of people dealing with both a mental health condition and a substance use disorder at the same time.
Dual diagnosis treatment in San Diego pairs mental health care and addiction care in one coordinated program. At San Diego Transformation Center, you get PHP, IOP, OP, and ambulatory (outpatient) detox from one team in one 15,000-square-foot location, so your care stays connected from intake through aftercare.
When mental health symptoms and substance use happen together, each one can feed the other. You need a single plan that treats both at the same time. Our integrated outpatient model coordinates psychiatric care and addiction treatment so you do not have to retell your story across separate providers.
You should not have to stitch together separate providers for conditions that fuel each other. Our one-team, one-location model delivers psychiatric care, addiction treatment, and supportive services in a single coordinated plan.
San Diego Transformation Center is certified by the California Department of Health Care Services (Cert. #370256AP, expires Oct 31, 2027), accredited by The Joint Commission for Behavioral Health Care, and LegitScript approved.
Co-occurring care at San Diego Transformation Center starts with an assessment, then builds one plan for the specific mix of mental health and substance use you are facing.
Mental health conditions we commonly treat include depression, anxiety, bipolar disorder, and PTSD or other trauma-related symptoms. Substance use we commonly address includes alcohol, opioids, stimulants, benzodiazepines, and cannabis. Your assessment confirms which conditions are present and which level of care fits.
Care is delivered at three outpatient levels, and you can step up or step down as your needs change.
| Level of care | Intensity and schedule | Primary focus | Who it is for |
|---|---|---|---|
| PHP (Partial Hospitalization Program) | Structured daytime programming most weekdays | Stabilization, symptom reduction, skill building | You need daily structure without an inpatient stay |
| IOP (Intensive Outpatient Program) | Several days per week | Applying skills to daily life, relapse prevention | You need strong support while managing work or school |
| OP (Outpatient Program) | Weekly individual and group therapy | Ongoing therapy, medication follow-up, relapse prevention | You are stable and want continued accountability |
Partial Hospitalization Program (5-6 hours daily): Intensive integrated treatment for complex or acute co-occurring conditions
Outpatient Program (1-2 sessions/week): Ongoing integrated care for sustained recovery
Ambulatory (outpatient) detox provides outpatient withdrawal support for clinically appropriate cases. You receive clinical monitoring and support while living at home, then move into PHP, IOP, or OP with the same team.
If a higher level of detox is clinically indicated, our team will help you find the appropriate setting and coordinate your return to outpatient care.

Outpatient care is built to fit around your responsibilities. PHP, IOP, and OP let you keep up with work, school, and family while you get consistent dual diagnosis treatment, and you can move between levels as your schedule or symptoms change.
Stability outside the clinic supports recovery inside it. For eligible clients, transitional housing and case management provide a steadier bridge between treatment and independent living.
Untreated symptoms and substance use can reinforce each other, which is why treating one at a time often leaves the other to pull recovery backward. Addressing both in the same plan, with the same team, helps you build coping skills and stability that hold together instead of competing.
You may be a good fit for our dual diagnosis program if you:
We accept most insurance plans and will work to maximize your benefits on your behalf. We can verify your coverage confidentially and walk you through your options by level of care.
Dual diagnosis treatment addresses a mental health condition and a substance use disorder at the same time. Your plan combines psychiatric care, therapy, and recovery skills in one coordinated approach.
It is most often called co-occurring disorders. Both terms describe having a mental health condition and a substance use disorder together.
A dual diagnosis means a person has both a diagnosable mental health condition (such as depression, anxiety, bipolar disorder, or PTSD) and a substance use disorder. An assessment confirms both.
Common approaches include CBT, DBT skills, EMDR for trauma, relapse-prevention work, medication management, and family therapy, coordinated under one plan.
PHP is higher-intensity daytime programming most weekdays, focused on stabilization and skill building. IOP meets several days per week and supports practicing those skills while you manage work or school.
Length depends on your needs and progress. Many people step down through levels of care over several weeks to a few months.
Treating both conditions together is the approach recommended by SAMHSA for co-occurring disorders, and it is associated with more stable, lasting recovery than treating one condition at a time. Results vary by person, and your plan is tailored to your situation.
