"Starting psychiatric treatment can feel overwhelming, especially if you've struggled finding effective treatment in the past. My goal is to provide thoughtful, individualized care built on thorough evaluation, evidence-based treatment, and a genuine commitment to helping patients achieve meaningful improvement in their mental health and quality of life."

Many patients come to Steffan after feeling frustrated by brief appointments that focus only on symptoms rather than the whole person. Every patient begins with a comprehensive psychiatric evaluation that explores medical history, psychiatric history, current symptoms, life circumstances, and treatment goals. This allows for thoughtful diagnosis and a personalized treatment plan genuinely tailored to you.

With more than 15 years of psychiatric experience across outpatient, inpatient, correctional, geriatric, adult, adolescent, and substance-use treatment settings, Steffan has supported people through nearly every kind of mental health challenge. That breadth means whatever you're carrying, it's likely something he has helped someone navigate before — with patience and without judgment.

Care Built Around the Full Picture

Mental health concerns are rarely one-dimensional. Effective treatment begins with understanding the complete clinical picture, not simply checking boxes or focusing on isolated symptoms. Through comprehensive evaluation and ongoing collaboration, treatment is tailored to your unique needs, goals, and circumstances.

What Sets True Haven Apart

Steffan is a devoted husband and a father of two young boys — and that life outside the office shapes everything he brings into it. Raising a family has deepened his belief in the things that matter most in care: empathy, patience, trust, and genuine human connection. He understands, firsthand, how much it means to feel truly seen and supported by someone who is fully present.

That perspective is one reason he practices differently from many large telehealth platforms and high-volume psychiatric clinics. Care is never rushed or impersonal. Instead, Steffan takes the time to understand each patient's unique experiences, challenges, goals, and circumstances in order to develop an individualized treatment plan.

Steffan's in-depth evaluations and meticulous attention to detail allow him to develop thoughtful, individualized medication management plans. Throughout his career, he has helped many patients achieve meaningful improvement, including individuals who previously struggled to find success with psychiatric treatment. His goal is not simply symptom management, but helping patients build lasting stability, resilience, and quality of life.

Steffan believes that trust is the foundation of effective mental health treatment — and trust is earned through consistency, honesty, and real relationship. He strives to create an environment where patients feel respected, supported, and actively involved in treatment decisions.

Most importantly, Steffan remains invested in each patient's long-term well-being — not simply managing symptoms or refilling prescriptions. He sees the whole person, walks alongside you through the ups and downs of healing, and stays committed to helping you build a life that genuinely feels better. That is the kind of care everyone deserves.

Steffan Weiner gave me hope that I could get well. After suffering an incorrect diagnosis and a raft of medications from another psychiatrist, Steffan listened carefully to me and correctly diagnosed my condition. Then he did DNA testing to see with which medication I would be compatible. He never forced me to make quick changes in my drug schedule. He responded graciously to my emails, always getting back to me within one day. I have my life back.

I have been seeing Steffen for less than a year and could honestly say it's been a positive impact. He is an incredibly articulate, intelligent and professional counselor but more than that he truly listens. I always feel heard, respected and understood in our sessions. I feel fortunate to have found such a skilled mental health practitioner.

Even when I struggle to find the right words, he understands what I'm trying to express. This kind of understanding means a lot. I'd recommend him to anyone looking for thoughtful and compassionate care.

Understanding Your
Mental Health

Clear, compassionate guides to the conditions we treat — written to help you feel informed, understood, and ready to take the next step. This is educational information, not a substitute for personalized care.

True Haven Mental Health is based in Thousand Oaks, California and provides telehealth psychiatric care throughout California. The resources below offer education, crisis support, recovery services, and community connections for individuals and families seeking mental health support. Whether you are looking for information about anxiety, depression, ADHD, bipolar disorder, schizophrenia, dementia, substance use disorders, or recovery support, these organizations provide trusted guidance and assistance.

Anxiety

Anxiety is more than ordinary worry. It is a persistent sense of unease, fear, or dread that can show up as racing thoughts, a pounding heart, trouble sleeping, irritability, or a constant feeling of being "on edge." When those feelings start to interfere with work, relationships, or daily life, it may be a sign of an anxiety disorder — one of the most common and most treatable mental health conditions.

Effective care usually combines an honest understanding of what triggers your anxiety with practical tools to quiet the nervous system, and — when appropriate — medication that takes the edge off so you can function and heal. The goal is never to numb you; it is to help you feel like yourself again. Many people are surprised by how much lighter life feels once anxiety is properly addressed.

Depression

Depression is not weakness, and it is not something you can simply "snap out of." It is a real medical condition that can drain your energy, flatten your mood, disrupt your sleep and appetite, and make once-enjoyable things feel hollow. Sometimes it looks like sadness; just as often it looks like numbness, exhaustion, or irritability — which is why it so frequently goes unrecognized, especially in people who keep showing up and pushing through.

Treatment is highly effective. A thorough evaluation looks at the whole picture — biology, life circumstances, sleep, and stress — to build a plan tailored to you, which may include medication, lifestyle changes, and connection to therapy. Recovery is not only possible; for most people it is the expected outcome with the right support.

Adult ADHD

ADHD does not disappear in adulthood — it just looks different. Instead of hyperactivity, adults often experience trouble focusing, chronic procrastination, disorganization, forgetfulness, restlessness, impulsivity, and a frustrating sense of underperforming despite real effort and intelligence. Many adults have spent years blaming themselves for struggles that actually have a name and a treatment.

A careful evaluation can bring clarity and, often, relief. Treatment may include medication that improves focus and follow-through, along with practical strategies for organization and routine. The right plan can be genuinely life-changing — helping you work with your brain instead of constantly fighting against it.

Bipolar Disorder

Bipolar disorder involves shifts in mood, energy, and activity that go beyond ordinary ups and downs — from emotional highs (mania or hypomania) to depressive lows. These swings can disrupt relationships, work, and a sense of stability, and they are frequently misdiagnosed as depression alone, which is why a thorough psychiatric evaluation matters so much.

With accurate diagnosis and steady, well-managed treatment, bipolar disorder is very manageable. Care focuses on stabilizing mood, protecting sleep, and building a sustainable long-term plan — so you can pursue your goals and relationships with confidence rather than fear of the next swing.

Trauma & PTSD

Trauma can follow a single overwhelming event or build up over time, and its effects are real: flashbacks, nightmares, hypervigilance, emotional numbness, difficulty trusting, and a nervous system that stays stuck in "high alert." These are not character flaws — they are the mind and body's attempt to protect you after something it could not process.

Healing is possible. Compassionate, trauma-informed care moves at your pace, helps your nervous system feel safe again, and can include medication to ease symptoms while deeper work happens. You deserve to feel grounded and present in your own life.

Medication Management

Psychiatric medication, when it is the right fit, can be a powerful part of feeling better — but it should never be a rushed, one-size-fits-all prescription. Good medication management means a careful evaluation, a clear explanation of options and trade-offs, thoughtful adjustments over time, and a provider who actually listens to how you are responding.

With more than 15 years of prescribing experience, Steffan approaches medication as a collaboration. The aim is the lowest effective approach that helps you feel like yourself — with regular check-ins, honest answers to your questions, and no pressure. You are always a partner in your own care.

Schizophrenia

Schizophrenia is a serious but treatable mental health condition that affects how a person thinks, feels, and perceives the world. It can involve hallucinations, delusions, disorganized thinking, and difficulty with motivation, concentration, or daily functioning. Symptoms often emerge gradually, and the experience can be frightening and isolating — both for the person living with it and for the people who love them.

With accurate diagnosis and consistent, compassionate treatment, many people with schizophrenia lead stable, meaningful lives. Care focuses on managing symptoms, supporting day-to-day functioning, and building a steady long-term plan — always with respect, never judgment. Early, ongoing support makes a real difference, and no one should have to navigate it alone.

Substance Use Disorders

Substance use disorders develop when alcohol or drug use begins to interfere with health, relationships, work, or daily life — often despite genuine and repeated efforts to cut back. They are medical conditions, not moral failings, and they frequently go hand in hand with anxiety, depression, trauma, or other mental health concerns that deserve attention too.

Recovery is possible, and it looks different for everyone. Effective care treats the whole person — addressing both the substance use and any underlying mental health conditions — with honesty, practical support, and no shame. Reaching out is a courageous first step, and meaningful change is within reach with the right help.

Dementia

Dementia is not a single disease but a group of conditions that affect memory, thinking, language, and the ability to carry out everyday tasks. It often begins subtly — misplaced items, repeated questions, trouble with familiar routines — and the changes can be confusing and worrying for families who aren't sure what is normal aging and what may need attention.

A thorough evaluation can bring clarity and a plan. While many forms of dementia are progressive, thoughtful care can help manage symptoms, support quality of life, and ease the journey for both the individual and their caregivers. Families do not have to figure it out alone — guidance, resources, and support are available at every stage.

Personality Disorders

Personality disorders involve long-standing patterns of thinking, feeling, and relating to others that can make relationships, emotions, and daily life feel persistently difficult. People may notice intense emotional reactions, recurring conflict, a shaky sense of self, or a feeling of being stuck in the same painful cycles despite their best efforts. These patterns are deeply rooted, but they are not permanent.

With understanding and the right treatment, real change is possible. Compassionate, evidence-based care helps build insight, steadier emotions, and healthier relationships over time. The goal is never to label a person, but to help them feel more grounded, more in control, and more connected to the life they want.

How Telehealth Works at True Haven

Telehealth psychiatry is simply care delivered by secure video, from wherever you feel comfortable. Because psychiatric care is built on conversation rather than physical exams, it translates beautifully to a virtual visit — often with less waiting, more flexibility, and the comfort of being in your own space.

Getting started is straightforward: book online, complete a brief intake, and meet with Steffan by secure video. He takes the time to understand your full story and builds a personalized plan from there. Whether you are new to psychiatric care or have felt unheard in the past, the goal is the same — care that meets you where you are.

Partnering With Treatment Centers to Support Long-Term Recovery

True Haven Mental Health provides psychiatric evaluation, medication management, and ongoing psychiatric care for individuals receiving treatment for substance use disorders throughout California. In-person evaluations can be made available for facilities local to the Thousand Oaks and surrounding areas.

Steffan Weiner, PMHNP-BC, brings more than 15 years of psychiatric experience and extensive experience working with patients affected by substance use disorders across detoxification, residential treatment, outpatient treatment, and psychiatric settings. He currently provides psychiatric services within substance use treatment programs and understands the unique challenges treatment facilities face in coordinating psychiatric care, supporting patient outcomes, and maintaining timely, high-quality clinical documentation.

Specialized Substance Use Treatment Experience

Steffan completed his psychiatric nurse practitioner substance abuse training at the Veterans Affairs Substance Abuse Treatment Clinic in Long Beach and has completed advanced training in evidence-based treatment of opioid use disorders, including:

  • Buprenorphine Education: Best Practices and Emerging Evidence in Opioid Use Disorder Treatment
  • Advanced Buprenorphine Education: Interactive Patient Cases
  • Building on Federal Prescribing Guidance for Buprenorphine Treatment

His experience includes psychiatric treatment of individuals struggling with:

Alcohol Use Disorder Opioid Use Disorder Stimulant Use Disorder Cannabis Use Disorder Sedative & Anxiolytic Use Disorder Co-occurring Psychiatric Disorders

Why Treatment Facilities Partner With True Haven

A Valuable Resource for Continuing Care

Many treatment facilities struggle to identify reliable psychiatric practitioners who understand both mental health and substance use recovery. Because of his extensive experience treating co-occurring disorders, Steffan is well-positioned to serve as a continuing-care resource for patients transitioning from detoxification, residential treatment, partial hospitalization programs (PHP), intensive outpatient programs (IOP), and outpatient recovery programs.

Patients who establish ongoing psychiatric care after treatment often experience improved continuity, medication adherence, symptom stabilization, and long-term recovery outcomes.

Facility Partnerships

True Haven welcomes opportunities to collaborate with detoxification centers, residential treatment programs, PHPs, IOPs, sober living environments, and other behavioral health organizations throughout California.

For partnership inquiries and referrals, please reach out directly:

steffan@truehavenmentalhealth.com (805) 616-2160

Many individuals entering substance use treatment also require ongoing psychiatric evaluation and medication management. Delays in psychiatric care can negatively impact engagement, recovery, and treatment outcomes.

True Haven helps facilities by providing:

  • Comprehensive psychiatric evaluations
  • Timely psychiatric follow-up appointments
  • Highly responsive staff communications within 24 hours
  • Medication management for co-occurring psychiatric disorders
  • Coordination with treatment teams when appropriate
  • Thorough, compliant clinical documentation
  • Telehealth services available throughout California
  • Continuity of care following discharge

Substance Abuse Facility
Post-Discharge Psychiatric Care

In addition to providing contracted psychiatric services within treatment programs, True Haven can serve as a trusted outpatient referral resource for patients transitioning out of detoxification, residential treatment, PHP, or IOP levels of care.

Continuity of psychiatric care following discharge is often one of the most important factors in maintaining recovery and preventing relapse. Because Steffan has extensive experience treating both substance use disorders and co-occurring psychiatric conditions, treatment teams can feel confident referring patients to a practitioner who understands the complexities of recovery and the ongoing psychiatric needs that frequently accompany it.

For facilities that prefer to maintain psychiatric services in-house, True Haven can also function solely as an outpatient referral partner, providing ongoing telehealth psychiatric evaluation, medication management, and follow-up care for patients throughout California after they leave treatment.

This creates a seamless transition from structured treatment into long-term psychiatric support, helping patients maintain stability, remain engaged in care, and continue making progress in their recovery journey.
