Narrative of Services:

The majority of my practice (~90%) focuses on OCD and anxiety. I provide therapy (generally 55- or 85-minute weekly sessions), psychodiagnostic assessment, and treatment planning/consultation. Current anxiety and OCD symptoms are primarily addressed with exposure and responsive prevention (ERP) and other empirically-supported practices based in cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and mindfulness.

Having practiced in many different settings (i.e., hospital-based, community mental health, private practice), I have had the opportunity to work with youth and their families from a variety of backgrounds. Working with youth with developmental disabilities has been a particular passion of mine. During my Postdoctoral Fellowship, I trained community mental health clinicians across San Diego in an empirically-supported intervention for youth with ASD and comorbid mental health concerns. I have implemented these techniques in work with youth with ASD and comorbid OCD/anxiety and have provided supervision for others working with these populations as well.

Facilities accessible by clients of all mobility levels (ADA accessible): Yes

Training Description:

I received my Ph.D. in Clinical Psychology from UCLA, where I trained at the UCLA Child and Adolescent OCD Program. I completed my Predoctoral Internship at UCSD/Rady Children’s Hospital (RCHSD) and my Postdoctoral Fellowship at the UCSD School of Medicine, during which time I provided consultation and training for clinicians in the RCHSD Anxiety and OCD Clinic. I have led workshops and lectures about OCD for therapists and psychiatrists at SDSU, RCHSD, and UCSD. I have also served as Clinical Supervisor at Rogers Behavioral Health San Diego and Los Angeles.

During my doctoral training, I conducted research focused on exploring parenting practices in families from diverse populations. In my Masters thesis, I explored differences in parenting practices between Latinx and Caucasian parents and how this impacted youth behavior problems. In my Dissertation, I examined parent-child conflict resolution in youth with or without developmental disability and their parents and related mental health outcomes.
