Addiction therapists & psychiatrists in Huntington Beach, CA

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!
