My practice provides in-person and telehealth treatment for adults and adolescents throughout California, with a primary focus on OCD, anxiety disorders, and related concerns. I have treated approximately 85 individuals with OCD and related disorders. I provide evidence-based treatment using Exposure and Response Prevention (ERP), Cognitive Behavioral Therapy (CBT), and Acceptance and Commitment Therapy (ACT). Treatment is individualized, collaborative, and culturally responsive. I work with varied OCD presentations, including harm, contamination, relationship, health, sexual-orientation, “just right,” and scrupulosity-related obsessions and compulsions.

I treat co-occurring anxiety disorders, depression, ADHD, and concerns related to perfectionism and emotional regulation. Treatment is individualized based on each client’s symptoms, needs, and goals. When OCD is the primary concern, exposure and response prevention (ERP) remains central, while cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and other evidence-based strategies are incorporated to address co-occurring symptoms. When appropriate, I also coordinate care with psychiatrists or other healthcare providers.

I am a California-licensed clinical psychologist and have treated individuals with OCD and related anxiety disorders since 2020, beginning during my doctoral internship at Kaiser Permanente. My specialized training and clinical experience include Exposure and Response Prevention (ERP), Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and diagnostic assessment. I have treated varied OCD presentations, including mental compulsions, reassurance seeking, checking, avoidance, contamination concerns, harm-related fears, scrupulosity, health anxiety, relationship-centered obsessions, and “just right” experiences. I regularly pursue continuing education focused on evidence-based OCD assessment and treatment.

My practice serves a culturally diverse population across California, including individuals from varied racial and ethnic backgrounds, faith traditions, socioeconomic circumstances, sexual orientations, gender identities, and family structures. I understand that culture, identity, family expectations, religion, stigma, and access to specialized care can influence how OCD symptoms are experienced and expressed. I strive to provide an affirming, culturally responsive environment and adapt treatment to each person’s identities, values, and lived experiences. Limited sliding-scale and pro bono services are available to help increase access to specialized care.

My doctoral education, clinical internship, postdoctoral training, and continuing education have included training in multicultural competency, cultural humility, implicit bias, identity development, and culturally responsive assessment and treatment. During my internship at Kaiser Permanente and throughout my subsequent clinical work in the Los Angeles area, I have worked with individuals from widely varied racial, ethnic, cultural, religious, socioeconomic, and LGBTQ+ communities. I approach cultural competency as an ongoing process that includes self-reflection, continued learning, and adapting evidence-based treatment to each patient’s cultural context, values, identities, and lived experiences.
