Narrative of Services:

Approximately 60% of the children and adolescents I see in private practice have OCD and/or an OC-related disorder.

Including IOP, individual therapy, and group therapy, I have treated upwards of 500 children and adolescents with OCD and/or an OC-related disorder since I have been independently licensed.

Training Description:

Currently I am on medical staff with Seattle Children’s Hospital working in the Mood and Anxiety Program, and I have been working in the Anxiety and OCD IOP for two years. I also provide outpatient care and assessment to children and adolescents with OCD and anxiety.

My training includes graduate training at the University of South Florida under the supervision of two members of the IOCDF Scientific Advisory Committee. I have also co-authored 4 peer-reviewed on PANS/PANDAS, which are published under my former last name (Gerardi), with individuals affiliated with USF, Yale, and NIMH.
