Trauma and PTSD therapists & psychiatrists in Simi Valley, CA

I'm a therapist offering in-person sessions in the Thousand Oaks area of Southern California, and telehealth to folks throughout California. I decided to become a therapist after many years of working in corporate America, and I have a Master's in Clinical Psychology and LMFT license.

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.

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'm a licensed psychotherapist with 34 years of experience. I do my best to meet you "where you are" and to offer compassionate presence as you progress through your personal process of self-discovery, self-identification, and evolution.

I'm honored to be part of your journey of transformation. I approach sessions in collaboration, as you learn to free yourself from judgment, criticism, and pain; to change negative perceptions that do not serve; and to experience more ease and peace in life.

I’m Dr. Marc Smith, a board-certified psychiatrist with extensive experience in treating a wide range of mental health conditions, including depression, anxiety, PTSD, and other complex challenges. I completed my medical training at Columbia University and my residency at the University of Southern California (USC). At my practice, I provide comprehensive psychiatric medication management and innovative treatment options tailored to those who have not found success with traditional approaches.

Hi! Are you curious about what therapy would be like? Or maybe you’ve gone before and are back for more? One of my first goals is to make sure you feel at ease with the therapeutic process. You don’t have to worry about what to say or where to start. It’s my honor and duty to ask the questions and listen intently. I’m here for you!

All roads lead to Rome! It doesn't matter where we jump in, if you’re ready, we’ll get there. My POV is through a Neurodiverse lens and incorporates Attachment Theory and C-PTSD with the idea that much of our conflict and distress stems from old wounds & unmet needs that can often be traced back to necessary adaptations needed to survive not only our families of origin but also societal norms and expectations. The gig of being human is hard and de-coding this blueprint can provide a path toward understanding, healing and, fulfillment. I utilize a variety of therapeutic modalities including Ketamine Assisted Psychotherapy.
