Couples therapists in Ontario, CA

My name is Sebastian Villaseñor, LCSW, and I hold an MSW from Cal State Fresno with ten years of clinical experience. I’ve worked with diverse populations in multiple settings, allowing me to adapt my approach to each client’s needs. I aim to create a supportive, welcoming therapy space where clients feel understood and empowered. Let’s work together toward growth, clarity, and lasting positive change.

I’m grateful to have a career that allows me to be authentically myself and spend my days talking deeply about things that matter. I love working with motivated, bright people who know they have a lot to offer, but feel a bit blocked. I find great joy in helping people unblock to find ease and authenticity in their own lives.

I’m a Licensed Marriage and Family Therapist based in Berkeley, California. I work with adults navigating trauma, anxiety, emotional overwhelm, life transitions, relationship patterns, and the lingering effects of difficult or painful experiences. Many of the people I work with are thoughtful, high-functioning, and insightful, yet still find themselves stuck in patterns that feel hard to shift alone.

My background includes training in EMDR, somatic and attachment-focused therapy, parts work, and ketamine-assisted psychotherapy. I earned my Master’s degree in Counseling Psychology from The Wright Institute. I also bring a mindfulness and body-based perspective to therapy through years of yoga and meditation practice.

My style is warm, collaborative, and depth-oriented while still practical and grounded. I especially enjoy working with complex trauma, highly self-aware clients, neurodivergent clients, and people who want therapy that goes beyond coping skills alone.

My goal is to create a space where you feel comfortable, understood, and supported. I know that seeking help for your mental health can take courage, and I deeply respect each person’s journey. I take time to listen, collaborate, and find a treatment plan that fits your individual needs and lifestyle. I value open communication and believe that healing happens best when we work together as a team.

Carolyn is driven by a vision to create a kinder humanity—one nervous system at a time. She believes therapy provides a space to explore safety in an uncertain world by fostering awareness of the connection between the heart, intuition, and the nervous system. Carolyn understands that while the nervous system doesn’t lie- judgments, perceptions, and assumptions can leave individuals feeling stuck, misunderstood, or exhausted.

I earned a double Masters in Clinical Psychology and Public Administration from the University of San Francisco. I have a B.S in Kinesiology and spent over 5 years working in Exercise Science/Fitness for the YMCA of SF. I am part of the Polyvagal Equine Institute (PVEI) community-spent the last 5yrs training in equine therapy. I have over 20yrs experience teaching dance, yoga & mindfulness.

Outside of work, Carolyn nourishes her own nervous system by walking in nature, swimming, practicing yoga, horseback riding, reading, and spending quality time with her family and her partner. She is also the co-host of a podcast with her longtime best friend, where they explore current events through a clinical and social services comedic lens.
