Sun Valley residents reach Quest Wellness Center with a quick trip south into North Hollywood, where its Joint Commission accredited team treats dual diagnosis in person, though the same program is on offer over secure statewide video. The program treats a mental health condition and a co-occurring substance use disorder in one plan, across morning, afternoon, and evening tracks through PHP, IOP, and outpatient care.
A dual diagnosis can be treated without ever checking into a hospital, and for most working adults in Sun Valley an outpatient program is both enough and far more livable. Quest handles co-occurring mental health and substance use disorders while a person stays home, keeps working, and holds up their responsibilities. Some of what turns up nearby is hospital-based or inpatient, which means handing over weeks of your life to a facility. Outpatient care delivers real clinical intensity on a schedule you attend and then leave, and for a lot of people that is the difference between getting help now and putting it off because stepping away into a facility felt impossible.
Sun Valley’s workweek shapes the design too. Between the industrial corridors off San Fernando Road and the households that run on early shifts, a program that only offered mid-morning slots would be useless here, which is why the morning, afternoon, and evening track structure matters more in this neighborhood than almost anywhere else Quest serves.
Some Sun Valley cases need one step before outpatient care can start: when the drinking or the drug use has reached the point where stopping abruptly is medically risky, stabilization has to happen first. Quest does not run inpatient detox, and it does not pretend to. Instead the team coordinates that step through Quest 2 Recovery, our own detox program, and takes the person straight into integrated outpatient treatment the moment they are medically stable. For families sorting this out in a crisis, that matters: one phone call reaches a team that can sequence both steps rather than leaving you to arrange a handoff between two unrelated providers.
Underneath it, a dual diagnosis is one situation with two moving parts, a mental health condition and a substance use disorder that keep setting each other off. One part is generally a low mood or an anxiety problem, though it might instead be trauma, bipolar illness, or ADHD; the counterpart is drink or a drug. Because the two drive one another, clearing just one leaves the other to restart it, and that is why they are treated on a single plan by a single team. It is the arrangement that keeps the mental health condition beneath an addiction from being left to fester while the substance use gets all the attention.
Prescribing at Quest is handled by a board-certified psychiatrist who works from the same plan treating the addiction, because a doctor who cannot see the substance use may reach for something that quietly cuts against recovery. Whatever is powering the use, a sunk mood, chronic anxiety, the swings of bipolar disorder, untreated ADHD, or sleep that has come apart, medication can bring it down far enough for the therapy to gain a hold, and where the addiction has an approved medication of its own, it sits in the same plan. It is never a substitute for therapy; it runs beside it.
The methods answer to the diagnosis, not to a fixed template. CBT reworks the mental habits that hold the symptoms and the using side by side; Dialectical Behavior Therapy builds the capacity to sit with a hard feeling without a substance; Motivational Interviewing takes a person from the readiness they actually hold. For a person whose using traces back to trauma, EMDR and trauma-focused sessions take that on directly. Themed groups make up most of the week, while individual sessions provide space for more private concerns. ACT, SFBT, psychodynamic therapy, and coordinated TMS care through Breakthrough TMS may be included when appropriate. Every group at Quest is led by a master’s-level therapist, supervised by licensed clinicians.
Quest runs three outpatient levels, and where a client from Sun Valley starts depends on how much the two conditions are disrupting daily life.
PHP | IOP | OP | |
Weekly load | Several hours, most weekdays | Fewer hours across the week | Lightest, spaced sessions |
Fits | Needing daily structure to stabilize | Holding a job through treatment | Maintaining gains |
Tracks | Daytime | Morning, afternoon, evening | Flexible |
Format | In-person or telehealth | In-person or telehealth | In-person or telehealth |
Partial Hospitalization is the most intensive, for people who need daily structure to steady both conditions. Intensive Outpatient steps down to fewer weekly hours across the three tracks. More information about this level of treatment is available on Quest’s North Hollywood IOP program. Outpatient maintains progress once things settle. The same team carries you across all three, and most clients step down through them as they stabilize.
Whether weekly therapy is still enough often becomes clear by looking at the past month. If mood improves only while using, appointments keep getting pushed aside, or someone you trust has started expressing concern, the current level of care may not be enough. Structured treatment across several days a week may be the better next step. The intake assessment determines the right level of care, confidentially and at no cost.

Nearby location pages also cover dual diagnosis treatment in North Hollywood and dual diagnosis treatment in Toluca Lake. For anyone who would rather stay home, the same program runs by telehealth statewide. If medical stabilization is needed first, it comes before this level of care: Quest does not run inpatient detox, so the team coordinates it with Quest 2 Recovery, our own program, and brings you into integrated care afterward.
