Co-Occurring Conditions
Co-Occurring Disorders & Dual Diagnosis Therapy in Downers Grove, IL
Specialized therapy for substance use disorders alongside anxiety, depression, trauma, or grief. Assessment, relapse prevention, and ongoing recovery coaching from a clinician with expertise in chemical dependency and addictions since 1991.

Integrated care may be right for you if
- You drink or use to manage anxiety, low mood, or memories you’d rather not have
- Past treatment addressed either your mental health or your substance use, but never both
- Sobriety has felt fragile because the underlying pain was never treated
- A relapse followed a loss, a diagnosis, or a stressful life change
- You’re in early recovery and want support that goes deeper than meetings alone
- A family member’s substance use is affecting your own mental health
Why treating both conditions together matters
Unlike most therapists who focus exclusively on either mental health or addiction, I specialize in dual diagnosis therapy, helping clients address the full picture of their emotional and behavioral health. When substance use is treated without addressing the anxiety, trauma, or depression underneath it, relapse becomes far more likely. When mental health is treated while substance use is ignored, progress stalls. Integrated care works because it is honest about how these conditions interact.
As a Licensed Clinical Social Worker and Certified Alcohol and Other Drug Counselor, I can provide assessment, psychotherapy, and substance use counseling within a single, coordinated plan. You will not be bounced between providers or asked to tell your story twice.
What co-occurring disorder treatment includes
Treatment is structured, nonjudgmental, and evidence-based. We move at a pace that protects your recovery while making real progress on the issues driving it.
- Comprehensive biopsychosocial assessment of substance use, mental health, medical history, and support systems
- Motivational Interviewing to resolve ambivalence and strengthen your own reasons for change
- CBT and DBT skills for cravings, emotional regulation, and distress tolerance
- Trauma-informed care that never forces disclosure before you are ready
- Relapse-prevention planning and recovery coaching for the long term
- Family sessions, when helpful, to repair trust and build a healthier home environment
- Coordination with physicians, psychiatrists, and treatment programs with your consent
Who I work with
I see adolescents (13+), adults, and older adults, including first responders, veterans, healthcare workers, and professionals whose careers make privacy and discretion essential. I also work with people whose substance use began during cancer treatment, chronic pain, or caregiving, where medical complexity requires a clinician who understands both sides.

Questions about co-occurring disorders therapy
