Bipolar disorder therapists & psychiatrists in Lake Forest, CA

I, truly, believe there is no "one size fits all" to therapy, so I aim to tailor the therapy experience to match each client's individual and unique needs. I collaboratively work with my clients as their co-pilot to help them navigate difficult emotional terrain, while empowering them, the expert of their own emotional landscape, to take the driver's seat because they are the expert of their own lived experiences.

I have been practicing therapy for over 15 years. I graduated from San Diego State in 2005 and have helped people work through problems ranging from anxiety and depression, to relationship and health problems. I have worked in residential and intensive outpatient programs but for the past 5 years I have been providing therapy through Telehealth. Mostly I have found people to be astounding in their strength and resiliency and have greatly enjoyed being part of their growth process.

I’m a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should feel human—not rushed or impersonal.

I provide a non-judgmental space where you can speak openly and feel understood. My approach integrates thoughtful medication management with psychotherapy when appropriate, always tailored to your individual needs.

Diagnosis can be an important part of understanding your experience, but it’s only one piece of the picture. I look at your mental, physical, and emotional well-being, as well as the life experiences that shape what you’re going through.

I offer collaborative, grounded care to help you move toward a more balanced, integrative, and holistic sense of well-being.

Nice to meet you!

If you’ve been dealing with depression, anxiety, panic, sleep problems, or mood swings, you may feel worn down, stuck, or unsure what to try next. You want relief, but also clear answers, practical options, and someone who takes your concerns seriously. I work with young adults, adults, and seniors who are ready to better understand what’s happening and take steady steps toward feeling more balanced and in control of their mental health.

I work with individuals, couples, and families navigating trauma, grief, anxiety, and relationship challenges. If you're seeking more short-term coping, we can explore the patterns shaping your experiences to support lasting, meaningful change. My approach is trauma-informed and attachment focused - always guided by your goals. Therapy is a warm, collaborative space where we process experiences, strengthen communication, and build more secure, fulfilling relationships.

Vanessa Diaz is a board-certified, licensed provider who offers expert mental health care for anxiety, depression, ADHD, PTSD, bipolar disorder, stressful life events, and many more conditions. Her goal is to help her clients live their best lives using modern, evidence-based solutions.

If trauma is still running your life, OCD has you trapped in cycles you can't break, or depression has left you feeling numb, stuck, and disconnected from the life you used to want—I want you to know: this can change, and you don't have to face it alone.

My path to this work started with my own mental health journey. I know what it feels like to struggle from the inside—and I know how life-changing the right support can be. That's exactly why I bring deep empathy, zero judgment, and evidence-based tools designed to create real, lasting change—not just coping, but building a life that feels like yours again.

I specialize in the treatment of anxiety, depression, ADHD, trauma-related disorders, PTSD, bipolar disorder, and OCD in adolescents and adults. As a Doctor of Nursing Practice and board-certified Psychiatric Mental Health Nurse Practitioner, I bring more than 20 years of nursing experience, including extensive work in critical care and neuro-trauma medicine. My approach combines evidence-based medication management, psychotherapy, and practical lifestyle interventions to help patients achieve meaningful and lasting improvement.
