Narrative of Services:

Over half of my practice focuses on treating OCD and related disorders, including body-focused repetitive behaviors (BFRBs), health anxiety, and perfectionism. Over the years I have treated many individuals with OCD and OC-related concerns in individual therapy, primarily working with adults and young adults. My services are fully virtual and include structured treatment plans, psychoeducation, and skills training grounded in Exposure and Response Prevention (ERP), Acceptance and Commitment Therapy (ACT), and CBT. I tailor each approach to the client’s needs and goals, with a focus on long-term progress and psychological flexibility related to intrusive thoughts and compulsive behaviors.

Training Description:

I have extensive clinical experience specializing in treating OCD and related disorders, including harm OCD, contamination, perfectionism, and intrusive thoughts. My training includes specialized workshops, consultation, and independent study in ERP, ACT, and CBT. I have also completed BFRB training through The TLC Foundation for BFRBs. My approach integrates evidence-based therapies, primarily ERP and ACT, to provide individualized, effective care. I remain committed to ongoing professional development to deepen my expertise and stay current with best practices in OCD treatment.

Diversity Statement:

I work with clients from a wide range of backgrounds, including BIPOC, LGBTQIA+, first-generation, and neurodivergent individuals. I focus on creating a safe, respectful space where clients feel comfortable bringing their full selves to therapy. I include conversations about identity, culture, and life experiences as part of the healing process.

I’ve completed coursework, trainings, and supervision focused on working with diverse populations and understanding how culture and identity affect mental health. I aim to offer therapy that respects each person’s background and lived experience, and I’m always learning how to be a more inclusive and supportive therapist.
