Psychotherapy Services for All Ages in San Mateo
Our practice is dedicated to empowering individuals, couples, and families to navigate life's challenges through compassionate, evidence-based psychotherapy. With over two decades of experience since obtaining my LCSW license in 1999, I specialize in creating a collaborative therapeutic environment that honors each client's unique journey. My approach integrates cognitive-behavioral, client-centered, and family systems theories, tailored to address issues ranging from trauma and anxiety to family dynamics and life transitions. I hold a Master of Social Work from Boston University and have directed mental health programs while providing clinical supervision, ensuring a deep understanding of both individual and systemic needs.

By combining play therapy for children, emotionally focused techniques for couples, and attachment-based strategies for families, I help clients uncover their inner strengths and foster meaningful growth. My commitment to accessibility includes offering teletherapy sessions and sliding fee options for those with financial constraints.

Sessions incorporate evidence-based techniques to build coping skills and improve academic performance through collaborative care with schools.

We utilize cognitive-behavioral techniques to develop coping strategies and enhance emotional resilience during critical developmental transitions.
Couples Therapy
Emotionally Focused Couples Therapy to strengthen relationships through improved communication and conflict resolution. Based on Gottman's research, our sessions rebuild trust and intimacy while addressing specific challenges like infidelity or life transitions. We help partners reconnect with shared values and develop sustainable relationship patterns through structured therapeutic exercises.
Family Counseling

We help families establish healthy boundaries, improve communication, and navigate transitions like divorce or loss. Sessions focus on enhancing sibling relationships and developing co-parenting strategies while addressing behavioral issues through a systemic lens that considers each member's unique perspective.
