Her approach is warm, collaborative, and grounded in the latest research in neuroscience and trauma treatment.

She considers it a privilege to walk alongside each client as they rediscover hope, deepen self-understanding, and create meaningful, lasting change.

Whether I’m diagnosing, prescribing, or simply listening, my mission is to make every patient feel seen, heard, and cared for. I strive to turn sessions into moments of trust, learning, and hope."

My goals as your therapist to help you address the factors in life —personal, familial, spiritual, academic etc.— that weigh heavy on you. Also, I'll introduce interventions that empower you to manage and strive the changes you want to make in your daily life. I specialize in working with clients who struggle with depression and anxiety.

I work with teens, young adults, and families navigating ADHD, anxiety, depression, substance use, identity exploration, family conflict, relationship challenges, life transitions, and emotional overwhelm. Whether you're feeling stuck, disconnected, overwhelmed, or uncertain about what comes next, therapy can provide a space to better understand yourself and move toward meaningful change.

My approach is warm, collaborative, and nonjudgmental. I believe therapy works best when clients feel genuinely understood, supported, and accepted for who they are. Together, we build on strengths, develop practical coping skills, and explore the patterns that may be getting in the way of living a more fulfilling life.

I strive to create a safe and supportive environment where clients can be honest, reflective, and fully themselves without fear of judgment. My goal is not only to help clients navigate current challenges but also to foster greater resilience, self-awareness, confidence, and connection.

Welcome, I'm Britney Jackson, a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) dedicated to helping adolescents and adults achieve better mental health through compassionate, evidence-based care. I understand that seeking help can feel overwhelming, and my goal is to provide a safe, supportive, and judgment-free environment where you feel comfortable sharing your story.

I specialize in treating anxiety, depression, ADHD, bipolar disorder, PTSD, trauma-related disorders, mood disorders, stress, insomnia, and other common mental health concerns. Whether you're struggling with persistent worry, low motivation, difficulty focusing, emotional ups and downs, or life transitions, I am committed to helping you find practical solutions that fit your unique needs.

Before becoming a Psychiatric Mental Health Nurse Practitioner, I spent several years as a registered nurse caring for patients in both inpatient medical and behavioral health settings. These experiences strengthened my ability to recognize complex mental health needs while providing compassionate, patient-centered care. Today, I combine psychiatric evaluations, medication management, psychotherapy, and patient education to help individuals achieve lasting emotional wellness.

My philosophy is simple: every person deserves to feel heard, respected, and empowered. Healing begins with trust, collaboration, and a treatment plan tailored to your goals, not a one-size-fits-all approach.

For over 20 years, I’ve had the privilege of helping individuals untangle the weight of trauma, stress, and life’s most difficult experiences. You don’t have to navigate this alone. Whether you’re feeling on edge, disconnected, overwhelmed, or stuck in patterns that no longer serve you, therapy can be a place to finally exhale.

I have expertise in treating anxiety, ocd, adhd, trauma, depression, addiction, recovery, and relationship challenges. I've had a private practice for over 10 years and work with adult clients at all stages of life. I earned my doctorate in Clinical Psychology at California Institute of Integral Studies, with intensive training at the Portia Bell Hume Center, Kaiser, UCSF, VA and the Jung Institute.

I'm a licensed therapist in California with over 18 years of experience, specializing in helping individuals, couples, and young adults with relationship issues, trauma, grief, intimacy, and confidence.
