Marsi specializes in working with children, teens, young adults, and women who are struggling with anxiety, trauma, life transitions, relationship challenges, and the lingering effects of difficult life experiences. She is passionate about helping clients understand not only what they're experiencing, but why—because insight creates the foundation for lasting healing.

Her approach is warm, collaborative, and grounded in the latest research in neuroscience and trauma treatment. Marsi integrates evidence-based therapies including EMDR, attachment-based therapy, Polyvagal Theory, somatic interventions, cognitive and behavioral approaches, and play therapy to help clients regulate their nervous systems, process painful experiences, strengthen relationships, and develop greater resilience.

Whether someone is healing from childhood wounds or abuse, breaking generational patterns, navigating a major life transition, or simply feeling overwhelmed by the demands of everyday life, Marsi believes lasting change is possible. She considers it a privilege to walk alongside each client as they rediscover hope, deepen self-understanding, and create meaningful, lasting change.

I came from Denmark to California for my own therapy and healing. After working for 20+ years as an educator and creating a family, I decided to pursue the road to become a therapist. I've worked with a diverse range of people, families, ages and challenges in humanistic, person centered, emotion focused schools, in psychodynamic community clinic, in substance use recovery center running groups and in a treatment center for clients suffering from eating disorders and co-existing conditions. Working in this field continues to give me an in depth understanding of the human soul and heart that I strive to use to help others heal.

I’m a licensed clinical social worker who specializes in helping children, adolescents, adults, couples, and families navigate anxiety, depression, panic, trauma, PTSD, and other life stressors. With experience in psychiatric crisis care and community outreach, I believe healing starts with feeling safe enough to show up. My goal is to offer real, judgment-free support that meets you where you are and helps you move toward lasting growth.

My goal with therapy is to provide a safe and open space to process and prioritize a growth mindset. I tailor my therapeutic approach to best match the needs of the client and truly believe in promoting acceptance. Some modalities I have experience with and may incorporate into therapy are Acceptance Compassion Therapy, Motivational Interviewing, Solution Focused, Client-Centered, Cognitive Behavioral Therapy, Here-and-now Counseling, Trauma-Informed, and Holistic. I have a passion for working with individuals who are looking to unpack complex emotions and experiences that have shaped their understanding of the world.
