For people in the Hollywood Hills, Quest Wellness Center runs its Joint Commission accredited dual diagnosis program a short way over the pass in North Hollywood, and streams the identical care by secure video to anyone who prefers to stay home. 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.
What decides whether dual diagnosis treatment works is the clinical model, not the setting it is dressed in. A good deal of the co-occurring care marketed around the Hollywood Hills leads with views, private chefs, and resort-grade rooms, none of which does anything on its own for a depression, an anxiety disorder, or an addiction. Quest is built out of the parts that actually carry weight: a board-certified psychiatrist directing medication, evidence-based therapy matched to the diagnosis, and one team running both conditions off a single plan. Because the care is outpatient, the money goes into treatment rather than lodging. The question worth putting to any program in these hills is what it does clinically, not what the property looks like in the photographs.
The clinical work starts with a proper psychiatric assessment, and a plan is only ever as sound as the diagnosis beneath it. Someone arriving with heavy stimulant use and a black mood might have a primary depression, or a depression the drug itself is manufacturing, and the two call for different treatment entirely. A board-certified psychiatrist sorts out which conditions are genuinely present, how they act on each other, and which is driving which, before a single medication or therapy is chosen.
This is the unglamorous work that decides whether treatment succeeds, the assessment underneath everything that follows, and it is exactly what determines whether the plan lands on the real problem or a decoy.
Set out plainly, a dual diagnosis is two conditions running together, a psychiatric one and a substance use disorder, each one feeding the other. The psychiatric half is often a depression or a long-running anxiety, and just as readily trauma’s aftermath, a bipolar pattern, or attention trouble, placed against a drink or a drug. What ties them into a single diagnosis is the loop between them, the condition driving the use and the use worsening the condition. Treating only one lets the other unpick the progress, which is the reason co-occurring disorders are handled together rather than one after another.
Prescribing here stays with a psychiatrist embedded in the treatment team instead of a prescriber off to the side, because in a dual diagnosis a drug chosen without sight of the substance use can quietly work against the recovery. Seeing the whole thing, the psychiatrist can aim a prescription at whatever is stoking the use, a flat mood, an anxiety that will not quit, bipolar swings, unmanaged ADHD, sleep in ruins, and ease it enough for the therapy to take hold. Any drug approved to treat the addiction is written into that plan as well. It is never handed over in place of therapy; it works next to it.
The methods are picked to suit the pairing rather than run off a standard list. Cognitive Behavioral Therapy goes after the thinking that props up the symptoms and the use at once; Dialectical Behavior Therapy grows the ability to withstand a hard feeling without a substance; Motivational Interviewing starts where a person’s readiness really is. Should trauma prove to be the thing at the bottom of it, the plan answers with EMDR and trauma-focused sessions aimed there. Most of the week is focused on themed group work, while individual sessions provide space for more private concerns. ACT, SFBT, psychodynamic therapy, and coordinated TMS care through Breakthrough TMS may be added 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 Hollywood Hills 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 details on intensive outpatient care are available through Quest’s 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.
The past month often shows whether a weekly session is still enough. If mood only steadies while using, appointments keep getting pushed, or someone close has started expressing concern, those patterns can point to the need for more structure. Multi-day outpatient care may be the next step. The intake assessment determines the right level of care, confidentially and at no cost.

The facility is at 10736 Burbank Blvd, North Hollywood, CA 91601, just over the pass from the Hollywood Hills by Cahuenga or the 101, and the Get Directions link below opens the route from where you are. For care across the wider area, see dual diagnosis treatment in Los Angeles. Quest also serves clients seeking dual diagnosis treatment in West Hollywood and dual diagnosis care in Studio City. 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.
Quest Wellness Center serves the Hollywood Hills from 10736 Burbank Blvd, North Hollywood, CA 91601, just over the pass by Cahuenga or the 101, with secure telehealth also available. You can do PHP, IOP, or outpatient care in the room or from home.
No, and around the Hollywood Hills that distinction matters: what treats a dual diagnosis is the clinical model, a psychiatrist, evidence-based therapy, and an integrated team, not the resort amenities much of the local market leads with. Quest puts the spend into treatment.
Because substance use can overlap with or intensify psychiatric symptoms. Stimulant use can resemble anxiety symptoms, while alcohol use can complicate depression. A proper psychiatric assessment helps determine which conditions are actually present before medication or therapy is chosen.
Yes. IOP and outpatient run morning, afternoon, and evening tracks, and telehealth removes the drive over the pass, so treatment fits around work or family.
Yes. A board-certified psychiatrist leads it for Hollywood Hills clients, over the pass or by video, prescribing for the depression, anxiety, bipolar disorder, ADHD, or ruined sleep that drives the use, with therapy alongside.
For Hollywood Hills clients, Quest treats co-occurring depression, anxiety, PTSD and complex trauma, bipolar disorder, and ADHD alongside alcohol or drug use. The mental health and substance use conditions are assessed together and treated within one plan.
What matters is starting, not the amenities. Call (818) 275-9810 or verify your insurance above and the clinical assessment gets scheduled.
