What dual diagnosis is
Mental Health and Substance Use, Treated Together
Dual diagnosis treatment in Orange County means care for a mental health condition and a substance use disorder at the same time, also called co-occurring disorders. At Exist, both are treated in one PHP or IOP plan by the same team. That plan uses Dr. Courtney Tracy's three-part model, which she built from more than a decade of clinical work with co-occurring disorders.
You can expect to not be stigmatized, and to be seen as a human in pain who can be helped.

How We Treat Both in the Same Week
In PHP or IOP, your groups, individual sessions, and somatic care all work on both conditions at once. A medical director for psychiatry can help with medication if you want it.

The Overlap
Your therapist looks at how your mental health and substance use affect each other, and builds one plan for both.

The Body
Somatic care uses yoga, mindfulness, and other therapies for physical pain and emotional ups and downs, and we look at nutrition and pain levels too.

The Mind
Cognitive work looks at the automatic thoughts that pop into your head and how they feed both your mood and your substance use.

The Team
Therapists, a case manager, a somatic practitioner, and medical directors for psychiatry and addiction medicine work together as one team.
From Our Founder
I solved the problem I had when struggling with my mental health, BPD, and addiction: no one knew how to help me.
Dr. Courtney Tracy · Founder and chief clinical officer
Dr. Courtney has spent more than a decade in practice, all of it with co-occurring substance use and mental health. She built Exist so both are treated together, by one team, in one plan.
