Bipolar disorder therapists & psychiatrists in Ventura, CA

I know how heavy life can feel when you’re carrying pain, uncertainty, or self-doubt. But I believe, as a wise old wizard once said, “Happiness can be found even in the darkest of places, if one only remembers to turn on the light.” My role is to help you find that light again. I work with Gen Z and Millennial adults facing anxiety, depression, trauma, bipolar disorder, ADHD, and more. Through integrative, culturally responsive care, I combine evidence-based psychiatry with holistic strategies to help you feel heard, supported, and empowered to create a life that aligns with your true self.

Welcome! I am Dr. Lyssabeth Mattoon, PhD, a clinical psychologist and trauma specialist, skilled at providing individual and family therapy for adolescents, children and adults. My calling in life is to support and empower trauma survivors to harness their inner strength as part of the healing process.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a DNP (Doctor of Nursing Practice) degree from the University of Massachusetts Global. I have experience working with adolescents and adults in multiple settings facing various complex mental health issues, including OCD, depression, anxiety, ADHD and mood disorders.

It is my prayer to build a practice that helps you reach a place where your mental health is truly at the forefront. My hope is that with each appointment—and each day—you feel supported in moving closer to the best version of yourself.

I am a Licensed Marriage and Family Therapist (LMFT) in California with a Master's degree in Clinical Psychology from Antioch University. Over the past 15 years, I have worked with a wide range of clients and have developed a practice treating substance use disorders, personality disorders, mood disorders, and executive functioning challenges. I am also trained in Dialectical Behavior Therapy (DBT) and incorporate evidence-based techniques tailored to each client's unique needs.

Before becoming a therapist, I earned a Juris Doctor and an MBA, experiences that give me a unique perspective on the complex personal, professional, and life challenges many clients face. Whether you are struggling with addiction, anxiety, depression, emotional regulation, relationship difficulties, or feeling stuck, my goal is to provide practical tools, compassionate support, and a collaborative environment where meaningful change can occur.

Many of the struggles that bring us to therapy—anxiety, trauma, relationship challenges, grief, self-doubt, or feeling stuck—have deeper roots than we realize. Sometimes these patterns develop through painful experiences, major life transitions, or family systems that taught us to prioritize others, question ourselves, or adapt in ways that no longer serve us. Therapy offers the opportunity to understand these patterns and create lasting change.

As a Licensed Marriage and Family Therapist and the spouse of a retired Army Veteran, I've spent much of my adult life living in different parts of the country and world, continually building community and connection wherever life led. Those experiences deepened my understanding of resilience, belonging, and the many ways people adapt through change, loss, and transition. I bring that perspective into my work, creating a warm, compassionate, and collaborative space where individuals, couples, and families feel genuinely seen and understood.

Together, we'll work to understand the deeper patterns shaping your life, strengthen your relationships, and help you move toward a more authentic, fulfilling way of living.

My passion is helping individuals find healing, balance, and inner strength. With compassion and care, I support clients as they navigate life’s challenges, building resilience, self-awareness, and emotional well-being along the way.‍I provide evidence-based treatment tailored to each person’s needs, drawing on mindfulness, trauma-informed approaches, and personalized care plans. My goal is to create a safe and supportive space where clients can reconnect with themselves and develop the tools for lasting wellness.
