Personality disorder treatment at Quest Wellness Center is structured outpatient care for personality disorders, including borderline personality disorder, delivered through partial hospitalization, intensive outpatient, and outpatient programs. Our care is built around Dialectical Behavior Therapy, the gold-standard treatment for BPD, with dual-diagnosis support for co-occurring conditions. Care is available in person or online. We accept most commercial PPO plans with out-of-network benefits.
Personality disorders are mental health conditions defined by long-standing patterns of thinking, feeling, and relating to others that differ markedly from what is expected and cause real distress or difficulty functioning. These patterns usually emerge by late adolescence or early adulthood, feel like an ingrained part of who a person is, and tend to show up most in relationships and in how a person handles emotions and stress. They are recognized medical conditions, not character flaws or a matter of being difficult, and they are treatable. Clinicians group personality disorders into clusters: the odd or eccentric types such as paranoid and schizotypal, the dramatic or emotional types such as borderline and narcissistic, and the anxious or fearful types such as avoidant and obsessive-compulsive personality disorder. Borderline personality disorder is the most commonly treated and the most studied, and it responds especially well to structured therapy. Treatment helps people change long-standing patterns, build skills, and improve their relationships and quality of life.
Borderline personality disorder is the most common reason people seek personality disorder treatment, and it is highly treatable with the right therapy. BPD is marked by intense and unstable emotions, a deep fear of abandonment, unstable relationships that swing between closeness and conflict, an unstable sense of self, impulsivity, chronic feelings of emptiness, and difficulty managing anger. Many people with BPD also experience self-harm and suicidal thoughts, which is part of why timely, specialized treatment matters so much. BPD often develops against a background of trauma, and it frequently occurs alongside depression, anxiety, PTSD, eating concerns, and substance use. For years BPD was considered difficult to treat, but that is no longer true: structured, skills-based therapy, especially DBT, produces meaningful and lasting improvement for most people. If you are having thoughts of harming yourself, you are not alone and help is available right now: call or text 988 to reach the Suicide and Crisis Lifeline, available 24/7, or call 911 in an emergency.
Dialectical Behavior Therapy, or DBT, is the most researched and effective treatment for borderline personality disorder, and it is the foundation of how Quest treats it. DBT was developed by psychologist Marsha Linehan specifically for BPD and chronic self-harm, and it has been shown to reduce suicidal thoughts, self-harm, and impulsive behavior while improving emotional stability and relationships. DBT works by teaching four core skill sets: mindfulness, to stay present and grounded; distress tolerance, to get through crises without making things worse; emotion regulation, to understand and manage intense feelings; and interpersonal effectiveness, to communicate needs and set boundaries while keeping relationships intact. What makes DBT effective is that these are concrete, practiced skills, not just insight, and a structured program is the ideal setting to learn and apply them. At Quest, DBT is delivered through individual therapy and skills groups within the program, so clients practice the skills and get support using them in real life.
While DBT is central, effective personality disorder treatment draws on several evidence-based approaches matched to the person and the specific disorder. Cognitive Behavioral Therapy (CBT) helps identify and change the distorted beliefs and behaviors that drive distress and conflict. Psychodynamic and schema-focused approaches explore the long-standing patterns and their origins, which is valuable across many personality disorders. Trauma-focused therapy, including EMDR, addresses the trauma that often underlies personality disorders, particularly BPD. Group therapy is especially powerful here, because personality disorders show up most in relationships, and group provides a place to practice new ways of relating with feedback and support. For personality disorders other than BPD, such as avoidant or obsessive-compulsive personality disorder, treatment is matched to the specific patterns involved. Most clients receive a combination across individual and group sessions, anchored by DBT skills and matched to their diagnosis.
No medication is FDA-approved to treat personality disorders themselves, but medication can help with co-occurring symptoms, and Quest’s medication management is led by a board-certified psychiatrist. Personality disorders frequently occur alongside depression, anxiety, mood instability, and sleep problems, and treating those conditions can reduce overall distress and make the core therapeutic work more effective. Any medication is used to support, not replace, the skills-based therapy that drives real change in personality disorders, and our prescriber coordinates it with the rest of the treatment plan. For clients who prefer to focus on therapy alone, that is a reasonable path, and medication can be revisited if co-occurring symptoms warrant it. The decision is made together, based on your symptoms, history, and goals.
Personality disorders rarely occur alone, so Quest treats them alongside the conditions that so often accompany them. Depression, anxiety, PTSD and trauma, eating concerns, and substance use are all common, and BPD in particular frequently co-occurs with several of these at once. Many people use alcohol or other substances to manage the intense emotions a personality disorder brings, which creates a cycle that worsens both. As a dual-diagnosis provider, Quest treats personality disorders and any co-occurring mental health or substance use condition in one coordinated plan rather than addressing them separately. Treating the personality disorder while leaving the depression, trauma, or substance use untouched is a common reason progress stalls, which is why integrated care is central to how Quest works.

Quest’s personality disorder treatment is built for adults whose symptoms are disrupting relationships, work, or emotional stability but who do not need round-the-clock hospitalization. You can keep up with daily responsibilities while attending a structured program, and you return home at the end of each treatment day. People typically start here when intense emotions and unstable relationships keep causing crises, when self-harm or impulsive behavior is a concern, when weekly therapy has not been enough to change long-standing patterns, or when a personality disorder is tangled up with depression, trauma, or substance use. The right level, from PHP down to outpatient, is set during an assessment so the support matches how much symptoms are affecting you. If symptoms are severe enough that staying safe is the immediate concern, our team helps arrange the right level of care and connects you with crisis support.
Dialectical Behavior Therapy (DBT) is the most researched and effective treatment for BPD. Developed specifically for it, DBT reduces self-harm and suicidal thoughts and improves emotional stability. Quest delivers DBT through structured outpatient care with individual therapy and skills groups.
Personality disorders are grouped into three clusters: odd or eccentric (such as paranoid and schizotypal), dramatic or emotional (such as borderline and narcissistic), and anxious or fearful (such as avoidant and obsessive-compulsive personality disorder). Borderline personality disorder is the most commonly treated.
Yes. BPD was once considered difficult to treat, but structured, skills-based therapy, especially DBT, produces meaningful and lasting improvement for most people. Quest treats BPD through DBT-based outpatient care with dual-diagnosis support.
DBT, Dialectical Behavior Therapy, teaches four skill sets: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. These concrete skills help manage intense emotions, reduce self-harm, and improve relationships. Quest delivers DBT through individual therapy and skills groups within the program.
No medication is FDA-approved for personality disorders themselves, but medication can help with co-occurring depression, anxiety, or mood instability. Quest’s psychiatrist manages this when appropriate, always alongside the skills-based therapy that drives change.
Yes. Quest is a dual-diagnosis provider and treats personality disorders alongside substance use, depression, anxiety, and trauma in one coordinated plan, which is what gives progress a durable foundation.
There is no fixed timeline, because changing long-standing patterns takes consistent practice. Structured outpatient care steps down through PHP, IOP, and OP as symptoms stabilize and skills take hold. Length is set by clinical recommendation, not a calendar.
Quest provides personality disorder treatment in person at our facility and through secure telehealth across California, so you can attend on site or from home. Call (818) 275-9810 to get started.

Quest treats personality disorders through a structured outpatient continuum, matching the intensity of care to how much symptoms are affecting daily life. Partial Hospitalization (PHP) is the most intensive level, with several hours of treatment on most weekdays, suited to people who need daily structure and skills practice to stabilize.
Intensive Outpatient (IOP) steps down with fewer weekly hours while keeping strong clinical support and ongoing DBT skills work. Outpatient (OP) is the lightest level, for maintaining progress and continuing to apply skills over the longer term. This structure is what makes personality disorder treatment work: changing long-standing patterns takes consistent practice, accountability, and support, far more than a single weekly session provides, and the program setting is where DBT skills are learned and reinforced. Most clients step down through the levels as they stabilize, and every level is available in person or through secure telehealth.
