Trauma and PTSD therapists & psychiatrists in Fullerton, CA

Sometimes a thoughtful conversation with the right person can make all the difference. As an experienced therapist, husband, and father, I bring both professional training and real-life wisdom to help people navigate life’s challenges. Over many years of both life and clinical work, I’ve had the privilege of helping people move through difficult seasons, gain clarity, and reconnect with their strengths. Whether this is your first time seeking therapy or you’re returning after time away, it’s normal to feel uncertain. Our first conversation is simply a starting point. I often work with people facing life transitions, relationship challenges, or feeling stuck, seeking clarity and a practical path forward. Together, we’ll slow things down, understand what’s happening, and identify steps that help move you forward. If you are going through a difficult season, you don't have to navigate it alone.

Hey there—I'm Mika, a Licensed Marriage and Family Therapist (LMFT) who's here for real talk and real support for adults and teens right here in Southern California. I've spent years helping people work through tough life events like trauma, addictions, ADHD, burnout from high-pressure jobs, anxiety, depression, and rocky relationships. What I love most is seeing folks step into their strength and build the life they want—I'm here to walk that path with you, no judgment, just genuine care.

Trauma-Informed. I specialize in treating adults with unresolved childhood traumas / C-PTSD. I deeply understand how early life experiences shape present-day struggles—I specialize in helping people heal from those roots, not just manage surface-level symptoms.

I am trained in powerful, evidence-based and experiential modalities like EMDR, IFS-informed parts work, Emotionally Focused Therapy, the Safe and Sound Protocol, and Ketamine-Assisted Psychotherapy. Not one-size-fits-all—I tailor treatment to each individual’s nervous system, attachment patterns, and inner world.

Most importantly, I show up as a therapist: I provide a warm, safe, and non-judgmental space where clients can be fully seen, heard, and validated. I understand that reaching out for help can feel overwhelming, and I meet clients with compassion, patience, and respect for their pace.

I am committed to helping clients work through inner emotional conflicts so they can move toward a more stable, fulfilling, and connected life—not just symptom relief, but real, lasting transformation.

I am a licensed clinical psychologist based in Ventura County, California. Since 2019, I’ve worked with older adolescents and adults across the state through Telehealth, as well as in person in my Westlake Village office. My clinical specialties include trauma and PTSD, anxiety, stress, and life transitions.

A bit about me personally: I’m an avid animal lover and proud dog mama to a boxer named Kevin!

If you are looking to become a better, happier, and healthier person and would like to gain a deeper understanding and love for yourself and others, I can help you. Psychotherapy can improve the quality of your life and/or manage more serious issues such as depression, anxiety, and grief. The process focuses on comfortably connecting with you in a confidential and empathetic, therapeutic setting.

Feeling worried all the time? Feeling down or depressed? Dealing with negative thinking that wont go away? Having difficulties in your relationships? Struggling to maintain a balance between responsibilities and everyday challenges?

Let me help you! I will guide you to effectively manage anxiety, depression or elevated stress that may arise when dealing with past or present relationship issues, family conflict, divorce, separation, parenting difficulties, trauma, illness, loss, transitions or other life stressors.

I'm here for you! Don't tackle this alone; open yourself to professional help.

I'm not just your therapist — I'm a mama who has been in the trenches too. After navigating my own postpartum experience and the heartbreak of pregnancy loss, I found my purpose: walking alongside mothers and families during some of life's most tender and transforming moments. Raising my amazing autistic son has also deepened my understanding of what it means to parent with love, resilience, and a whole lot of grace.

I believe healing happens when you feel truly seen — not judged, not rushed, just held. My approach is rooted in authenticity and compassion, creating a space where your full story is welcome. Whether you are struggling with postpartum depression, anxiety, grief, or the emotional weight of a special needs diagnosis, you do not have to carry it alone.

This work is personal to me. And that's exactly why I show up the way I do.
