I believe therapy should be a place where you don't have to keep holding everything together.

Many of the women I work with are thoughtful, capable, and deeply committed to the people they love. They're balancing careers, motherhood, relationships, and countless responsibilities, yet internally feel anxious, overwhelmed, or emotionally exhausted.

I specialize in supporting overwhelmed working moms and high-achieving women navigating anxiety, postpartum mental health, fertility and IVF, burnout, and major life transitions. I also provide culturally responsive therapy for AAPI adults navigating family expectations, identity, and cultural stress.

I hope that you'll feel understood from the very beginning and know you don't have to carry everything on your own.

I believe that most people are either stuck repeating a cycle of generational trauma, or carrying the burden of bravely breaking that cycle. You deserve to break that cycle by discovering and embracing your best self, without fear or shame. But I understand that this is not always easy. I can help you break down the barriers that prevent you from achieving your goals and assist you on a transformative journey to becoming the person you want to be. Therapy is a process of the human spirit requiring courage, creativity, and self-compassion and I welcome you to join me.

I work with teens, adults, and couples. I believe that true wellness comes from integrating all aspects of ourselves—spiritual, social, emotional, intellectual, physical, and creative. As a California-certified sexual assault counselor, fully trained in EMDR and Brainspotting, I provide trauma-informed care with empathy and expertise. I also specialize in psychedelic therapy preparation and integration, guiding clients through their profound journeys with care and intention.

I specialize in supporting adolescents, adults, and families navigating trauma, systemic stress, life transitions, anxiety, depression, and relationship challenges. With 11 years as a Licensed Clinical Social Worker, I’ve worked across diverse communities, including Black, Native American, Veteran, and criminal justice-involved populations. Clients often describe me as grounded, direct, and compassionate, and I bring deep respect for each person’s lived experience into the work we do together.

I am a Licensed Marriage and Family Therapist located in Marin County, California. My education and training have been centered on being trauma-informed and working with individuals, couples, and families.
