Dual Diagnosis Treatment in Arizona
When a mental health condition and a substance use disorder are both present, one team treats both under a single plan — instead of sending you elsewhere for half the problem.
Now serving Wisconsin — a new Legacy residential facility is opening in Mukwonago.

The Facts of Dual Diagnosis
Two conditions, one person — and they have to be treated together.
Dual diagnosis means a mental health condition and a substance use disorder are present at the same time. Traditional care splits them: a rehab treats the substance use, a separate provider treats the psychiatric condition, and neither sees the whole picture. Each one drives the other, so treating them in sequence tends to produce a revolving door rather than recovery.

Do You Need Treatment?
Dual diagnosis is usually why treatment didn't hold last time.
If someone has completed treatment before and relapsed quickly, an untreated psychiatric condition is one of the most common reasons. If these patterns sound familiar in you or someone you love, it’s worth a confidential conversation, at no cost and with no obligation.
01
Treatment that keeps not sticking
Multiple programs, real effort, and a return to use within weeks or months each time. When the pattern repeats, the problem is usually what went untreated — not a lack of commitment.
02
Using to manage symptoms
Drinking or using to quiet anxiety, lift depression, blunt trauma memories, or force sleep. The substance works briefly, then makes the underlying condition worse, which increases the need for it.
03
Symptoms that persist after stopping
Weeks into abstinence, the depression, panic, mood swings, or intrusive memories are still there. That is a strong signal there is a psychiatric condition of its own, not just aftereffects of use.
04
Being turned away or handed off
Programs that decline to admit someone until their psychiatric symptoms are stable, or psychiatric providers who won’t treat until the substance use stops. That gap is where people fall through. Note that Legacy does not offer detox services; when detox is appropriate, it must be completed elsewhere before residential care begins.
Some individuals may require medical detoxification or stabilization before beginning residential treatment. Our admissions team can help determine the appropriate level of care and coordinate with an outside provider when necessary.
Treating Dual Diagnosis
One team, one plan, both conditions.
Legacy Recovery Center provides residential dual diagnosis treatment in a comfortable, private home in Arizona, for clients who have completed detox independently or through a licensed detox provider. Our mental-health-first model was built for exactly this population: care begins with a full psychiatric evaluation by our physician owners, so the treatment plan is based on what is actually driving the substance use rather than assumptions. Medication management, individual therapy, group work, trauma-focused care, and family therapy are delivered by the same small clinical team, which means the psychiatrist treating the depression and the therapist treating the addiction are talking to each other daily. Common pairings we treat include depression, anxiety, bipolar disorder, PTSD, and personality disorders alongside alcohol, opioid, stimulant, or polysubstance use. Discharge planning coordinates continued psychiatric care, not just recovery support.

Care plans are developed for each person

THERAPIES & TREATMENT MODALITIES
Therapies selected for your individual needs.
No single modality suits everyone, so treatment plans here draw on several. Which ones you work with depends on your history, your diagnosis, and what actually helps.
Core evidence-based
Cognitive behavioral therapy (CBT)
Identify and change the thought patterns and behaviors that keep symptoms going.
Emotion regulation
Dialectical behavior therapy (DBT)
Mindfulness, distress tolerance, and emotion regulation — skills for the hardest moments.
Trauma-focused
EMDR
Structured processing of traumatic memories that so often sit underneath addiction.
Mind-body integration
Somatic experiencing
Body-centered work addressing stress and trauma held in the nervous system.
Change-focused
Motivational interviewing
A collaborative approach that strengthens your own reasons and readiness to change.
Trauma resolution
Accelerated resolution therapy (ART)
Eye movements and visualization that may help reduce the distress attached to difficult memories.
Holistic integration
Parts-based interventions (IFS)
Working with the parts of you in conflict, toward internal steadiness.
Nervous-system regulation
Safe and Sound Protocol
An auditory intervention that may support nervous-system regulation alongside therapy.
Community healing
Group therapy
Process, psychoeducation, and skills groups — recovery alongside people who understand.
CONDITIONS WE TREAT
What we're equipped to treat — and what we're not.
Legacy treats adults in a residential setting across two levels of care — Primary Mental Health RTC and Substance Abuse RTC — including any combination of the conditions below. Honesty is part of care: if we’re not the right fit, we’ll tell you, and help you find who is.
We do not offer medical detox. When detox is needed, we refer you to a trusted partner first — then you transition to Legacy for residential treatment.
THE LEGACY DIFFERENCE
Doctors who answer to you — not investors.
Legacy is owned and led by the two psychiatrists who founded it. That changes how decisions get made, from your treatment plan to how long you stay.
01
Physician-owned and led
Founded and run by Dr. Roland Segal, MD and Dr. Ehab Abdallah, MD — board-certified psychiatrists involved in care every week.
02
Mental health treated first
Every stay starts with a psychiatric evaluation, so the conditions driving substance use are treated — not just the symptoms.
03
A home, not a hospital
Private residences in quiet neighborhoods — real bedrooms, shared meals, and space to breathe.
04
Personalized treatment plans
Your plan is built around your history and goals, and adjusted weekly as you progress.
05
In-network insurance
In-network with Cigna and Aetna, with benefits usually verified the same day you call.
06
24/7 admissions
You’ll reach our admissions team directly — any hour, any day. For a medical emergency, call 911 or go to the nearest emergency department.
The First Step Is to Seek Help
You don't have to do this alone.
Treating one condition and leaving the other alone is the most common reason recovery doesn’t hold. Substance use and psychiatric illness feed each other, and the people caught between them are often bounced between providers who each treat half the problem.
Care in a residential setting is designed to support recovery. You’ll work with licensed clinicians and receive psychiatric care from our owners, Dr. Roland Segal and Dr. Ehab Abdallah. You’ll step away from the environment tied to your drinking, and be surrounded by others facing the same challenge.

FAQ
Frequently asked questions about dual diagnosis treatment
Have questions about treatment, insurance, or what to expect? We’ve answered the most common ones here. If you don’t see yours, our team is always available.
It means a mental health condition and a substance use disorder are present at the same time — for example depression alongside alcohol use disorder, or PTSD alongside opioid dependence. Both are primary conditions and both need treatment.
Both, together. Sequencing them is what fails most people: treating the substance use alone leaves the driver in place, and treating the psychiatric condition alone leaves the behavior in place. One team holds both halves of the plan.
No. Legacy does not offer detox services. If detox is appropriate, it must be completed elsewhere under medical supervision first; we coordinate with licensed detox providers and welcome you into residential care once it’s complete.
Depression, anxiety disorders, bipolar disorder, PTSD and complex trauma, and personality disorders are the most common. Psychiatric evaluation at admission determines what is actually present rather than assuming.
Most adults stay between 30 and 90 days. Length of stay is individualized and built around your clinical needs and progress, with 24-hour structured residential support throughout. Co-occurring conditions often need somewhat longer to stabilize.
