Psychologist & Social Worker
I am a dual licensed Clinical Psychologist (#29917) and Licensed Clinical Social Worker (#26862), in the state of California, with over 15 years of clinical experience. I have treated clients with wide-ranging issues from serious persistent mental illness to temporary situational issues that have disrupted their lives. Treatment has been in a variety of settings and at various stages of life, helping them through many life challenges and transitions.

I specialize in Gender-Affirmative Therapy and Suicide Prevention and am a member of the World Professional Association for Transgender Health (WPATH), using the Standards of Care version 7 to individually tailor therapeutic interventions.

my approach
I approach each client based on their individual needs and believe that there is no one-size-fits-all model in health care, especially gender-affirming care. I use psychodynamic, cognitive-behavioral, feminist, relational, humanistic and strengths-based modalities and theoretical frameworks to inform my practice. It is my professional goal that you grow a greater understanding of yourself and feel stronger from our work together, whether you see me for one or many sessions.
